Association of occupational stress and social support with health-related behaviors among chinese offshore oil workers

To explore the relationship of occupational stress and social support with health-related behaviors of smoking, alcohol usage and physical inactivity, a cross-sectional survey was conducted among 561 offshore oil installation workers of a Chinese state-owned oil company. They were investigated with a self-administered questionnaire about socio-demographic characteristics, occupational stress, social support and health-related behaviors. Logistic regression analysis was used to study the association between occupational stress, social support and health-related behaviors and adjusted for age, educational level, marital status, duration of offshore work and job title. Of 561 workers, 218 (38.9%) were current smokers, 124 (22.1%) current drinkers, and 354 (63.1%) physically inactive in their leisure time. Further multivariate logistic regression analysis indicated that: (1) Current smoking was significantly negatively related with perceived stress from "Safety" (OR=0.74; 95% CI=0.58-0.94) and lack of supervisors' instrumental support (OR=0.34; 95% CI=0.18-0.65); (2) Current drinking was significantly positively related to perceived stress from "Interface between job and family/social life" (OR=1.32; 95% CI=1.02-1.70) and "Organizational structure" (OR=1.35; 95% CI=1.06-1.74), but was significantly negatively related to poor emotional support from friends (OR=0.54; 95% CI=0.62-0.96); (3) Physical inactivity after work was significantly positively associated with perceived stress from "Safety" (OR=1.44; 95% CI=1.16-1.79) and lack of instrumental support from both supervisors (OR=1.74; 95% CI=1.16-2.65) and friends (OR=1.68; 95% CI=1.06-2.42). The findings suggest that psychosocial factors of occupational stress and social support at offshore oil work might affect workers' health-related behaviors in different ways.     

Colorectal Cancer Screening Among Primary Care Patients: Does Risk Affect Screening Behavior?

Lifestyle factors including smoking, obesity, and diabetes can increase colorectal cancer (CRC) risk. Controversy exists regarding screening rates in individuals at increased CRC risk. To examine the effect of risk on CRC screening in primary care, cross-sectional data collected during January 2006–July 2007 from 720 participants in 24 New Jersey primary care practices were analyzed. Participants were stratified by risk: high (personal/family history of CRC, history of polyps, inflammatory bowel disease), increased (obesity, Type II diabetes, current/former smokers), and average. Outcomes were up-to-date with CRC screening, receiving a physician recommendation for screening, and recommendation adherence. Chi-square and generalized linear modeling were used to determine the effect of independent variables on risk group and risk group on outcomes. Thirty-seven percent of participants were high-risk, 46% increased-risk, and 17% average-risk. Age, race, insurance, education, and health status were related to risk. High-risk participants had increased odds of being up-to-date with screening (OR 3.14 95% CI 1.85–5.32) and adhering to physician recommendation (OR 7.18 95% CI 3.58–14.4) compared to average-risk. Increased-risk participants had 32% decreased odds of screening (OR 0.68, 95% CI 0.42–1.08). Low screening rates among increased-risk individuals highlight the need for screening interventions targeting these patients.     

The Simultaneous Presence of Health Risk Behaviors in Freshman College Students in Brazil

The objective of this study was to assess the prevalence and factors associated with simultaneous health risk behaviors in freshmen college students enrolled in a Brazilian university. We interviewed 738 students (59.2% men) with average age of 20.1 years (CI 95%: 19.8–20.5). The risk behaviors assessed were smoking habit, alcohol use, unhealthy diet and physical inactivity. Independent variables were sex, age, employment, marital status, maternal education, study shift and socioeconomic level. It was found that 8.7% were smokers, 45.9% showed alcohol abuse, 59.4% had inadequate diet and 18.5% were physically inactive. Of the students, 20.2% showed no risk behavior, 39.1% one behavior, 29.0% two risk behaviors and 11.7% three and/or four risk behaviors. Males (OR: 2.04, CI 95%: 1.13–3.67) and night shift students (OR: 1.83, CI 95%: 1.01–3.33) were more likely to have three and/or four risk behaviors. Health promotion interventions focusing simultaneous behavior changes should be employed at the university.     

Lifestyle-Related Determinants of Hookah and Cigarette Smoking in Iranian Adults

To identify lifestyle-related determinants of hookah and cigarette smoking in Iranian adults, a total of 12,514 men and women aged ≥19 years in three counties in central Iran (Isfahan, Najafabad, Arak) were selected in multistage random sampling. Data on socio-demographic characteristics and lifestyle were collected in interviewer-administered questionnaires, as part of the baseline survey of the Isfahan Healthy Heart Program. Unhealthy lifestyle-related factors independently associated with cigarette and hookah smoking, were identified in sex-specific multivariate logistic regression analyses. High stress levels (OR: 1.55; 95% CI: 1.35–1.78 for men; OR: 1.63; 95% CI: 1.17–2.27 for women), family member smoking (OR: 1.61; 95% CI: 1.27–4.92 for men; OR: 2.49; 95% CI: 2.20–2.95 for women), and short/long sleep duration (OR: 1.18; 95% CI: 1.01–1.39 for men; OR: 1.52; 95% CI: 1.10–2.35 for women) were associated with cigarette smoking in both men and women. Poor diet was also related to cigarette smoking in men (OR: 1.55; 95% CI: 1.62–1.89). Family member smoking was associated with hookah smoking in both men (OR: 1.16; 95% CI: 1.05–3.12) and women (OR: 1.56; 95% CI: 1.02–4.92), and in addition high stress levels (OR: 2.87; 95% CI: 1.14–5.83) and short/long sleep duration (OR: 1.07; 95% CI: 1.02–2.41) were associated with hookah smoking in women. Unhealthy lifestyle-related factors co-occur with cigarette and hookah smoking in Iranian adults, likely increasing the risk for chronic health problems. Sex differences in the determinants of hookah and cigarette smoking may need to be taken into account in planning tobacco control strategies.     

Socioeconomic determinants of children's environmental tobacco smoke exposure and family's home smoking policy

Background: Few studies have analysed the impact of differentsocioeconomic indicators on the prevalence of children's environmentaltobacco smoke (ETS) exposure at several indoor environmentsand on family's home smoking policy. Methods: Dataon 12 422 pre-school children (48% female) from two cross-sectionalsurveys conducted during 2004–06 in Germany were analysed.Exposure assessment was based on parental report. Independenteffects of socioeconomic indicators were determined by mutuallyadjustment in logistic regression analyses. Results: Lowparental education, unemployment, low household equivalent income,non-German nationality, single-parent family and family sizewere independently associated with children's ETS exposure athome and in cars. The strongest associations were observed forlow parental education [at home: adjusted odds ratio (OR) 3.94;95% confidence interval (CI) 3.46–4.49; in cars: 5.00;3.84–6.50]. Indicators of material living conditions (relativepoverty: 0.48; 0.39–0.57, parental unemployment: 0.55;0.46–0.65), as well as single-parent family, non-Germannationality and family size, but not parental education, wereindependently associated with ETS exposure at hospitality venues.Smoking households with low parental education, unemployment,poverty, single-parent family and non-German nationality wereless likely to have the rule of exclusively smoking on the balconyor terrace. Low parental education and unemployment were negativelyassociated with no smoking in presence of the child in householdswith smoking inside the flat. Conclusion: Severaldimensions of socioeconomic position have to be considered inexplanations of social inequalities in children's ETS exposureand family's home smoking policy as well as in development oftargeted interventions.     

Contribution of adolescent and early adult personality to the inverse association between education and cardiovascular risk behaviours: prospective population-based cohort study

BACKGROUND: The role of early personality in socioeconomic inequalities in health is not well understood. We investigated the extent to which type A components in adolescence and early adulthood contributed to the inverse association between education and behavioural cardiovascular disease risk factors in adulthood. METHODS: Prospective cohort study with a population-based random sample of 477 men and 648 women, aged 12-21 years at baseline. Baseline data included information on pathogenic and protective components of type A behaviours (impatience, aggression, hard-driving, and engagement-involvement) and parental education. The 9-year follow-up data included information on the participant's educational level and health behaviours (smoking, alcohol consumption, physical inactivity, butter use). RESULTS: After adjustment for parental education, high levels of impatience and low levels of hard-driving in adolescence and early adulthood predicted low educational level in adulthood (Ps < 0.01 for men, Ps < 0.001 for women). Adulthood education was inversely associated with smoking in women and men (odds ratios [OR] = 8.5 and 7.9, 95% CI: 3.4-18.4 and 3.1-23.9, respectively), and with physical inactivity in women (OR = 5.4, 95% CI: 2.6-11.4). In men, components of type A behaviour explained 28.5% of the inverse association between education and smoking, even after controlling for parental education. In women, the corresponding proportions were 20.5% and 17.7% for smoking and physical inactivity, respectively. CONCLUSIONS: The inverse associations of adulthood education with smoking in men and women and physical inactivity in women may be partly rooted in personality-related factors present earlier in life. Our evidence suggests that personality should be studied as a potential contributor to socioeconomic differences in health behaviours.     

Education, income, occupation, and the 34-year incidence (1965-99) of Type 2 diabetes in the Alameda County Study

BACKGROUND: Lower socioeconomic position (SEP) is related to higher prevalence of Type 2 diabetes, yet little is known about the relationship of SEP with incident diabetes. METHODS: The association between SEP, measured by self-reported education, income, and occupation, and Type 2 diabetes incidence was examined in a community sample of 6147 diabetes-free adults from Alameda County, CA. Cox proportional hazards models estimated the effect of baseline (1965) and time-dependent (value changes over time) measures of SEP on incident diabetes over a 34-year study period (1965-99). Demographic confounders (age, gender, race, and marital status) and potential components of the causal pathway (physical inactivity, smoking, alcohol consumption, body composition, hypertension, depression, and health care access) were included as fixed or time-dependent covariates. RESULTS: Education, income, and occupation were associated with increased diabetes risk in unadjusted models. In baseline models adjusted for demographics, respondents with <12 years of education had 50% excess risk compared with those with more education [hazard ratio (HR) = 1.5, 95% confidence interval (95% CI) 1.11-2.04], but income and occupation were no longer significantly associated with increased risk. Further adjustment minimized the significance of all associations. Time-dependent effects were consistently elevated for low education and male blue-collar occupation, but non-significant after full adjustment (HR = 1.1, 95% CI 0.79-1.47 and HR = 1.3, 95% CI 0.91-1.89, respectively). CONCLUSIONS: Socioeconomic disadvantage, especially with low educational attainment, is a significant predictor of incident Type 2 diabetes, although associations were largely eliminated after covariate adjustment. Obesity and overweight appear to mediate these associations.     

The association between amount of cigarettes smoked and overweight, central obesity among Chinese adults in Nanjing, China

OBJECTIVES: To examine the association between overweight, central obesity and cigarette smoking (total amount of cigarettes smoked [TACS] and status). DESIGN: Population-based cross-sectional study. Setting: Administrative villages and neighborhoods (n=45) randomly selected from three urban districts and two rural counties in Nanjing City, China. SUBJECTS AND METHODS: A representative sample (n=13,463) of permanent local male residents aged 35 years or older; 66.5% were urban residents. The response rate was 90.1%. Overweight (BMI>=24) and central obesity (waist circumference>=85 in men) were defined according to the new Chinese standard. The association between smoking (amount and status) and obesity was examined using logistic and linear regression analysis. RESULTS: The overall prevalence of overweight was 36.1% (29.7% with 24<=BMI<28 and 6.4% with BMI>=28). After adjusted for age, residence, education, occupation, family income, alcohol drinking, dietary intake, occupational and leisure-time physical activity, the prevalence was significantly lower among current smokers (33.0%) than in non-smokers (39.9%) and ex-smokers (39.2%), respectively (p<0.05). The amount of cigarette smoked was reversely associated with BMI (compared to non-smokers, ORs and 95%CIs for smokers with low-, medium- and high-TACS were 0.88 [0.79, 0.98], 0.77 [0.69, 0.86], and 0.77 [0.69, 0.86], respectively). The prevalence of central obesity was 35.9%. Compared to nonsmokers, only male ex-smokers were at increased risk of central obesity (OR=1.38, 95%CI=1.10, 1.74), while there was no significant association with current- smokers (OR=1.02 [0.92, 1.12]). The amount of cigarette smoked was not significantly associated with central obesity. CONCLUSIONS: Cigarette smoking was negatively associated with body weight indicated by BMI but not with central obesity indexed by waist circumference in Chinese men. Cessation of smoking may increase the risk of gaining overall body weight and developing central obesity. Cigarette smoking prevention and cessation should be a public health priority in China.     

Is Inflammation a Causal Chain between Low Socioeconomic Status and Type 2 Diabetes? Results from the KORA Survey 2000

Low socioeconomic status (SES) is associated with type 2 diabetes. Inflammatory markers like C-reactive protein (CRP) are predictive of diabetes. It is unclear, whether inflammation may be a mechanism linking low SES to type 2 diabetes. In the population-based KORA Survey 2000, 766 men and 710 women aged 55 to 74 years were randomly selected in the Augsburg region (Southern Germany). An index for SES was defined using education, occupation, and income. In women but not in men, increased CRP concentrations were found with lower SES (p<0.01). This significant trend was no longer observed after adjusting for BMI and waist circumference (p=0.23). Low SES was significantly associated with the age-adjusted odds of having type 2 diabetes both in men (OR; 95%CI: 1.35; 1.14–1.60) and in women (2.01; 1.37–2.96). The risk of having diabetes associated with low SES was only slightly changed after adjusting for CRP, which was itself significantly related to diabetes. In multivariate analyses, adjusting for age, obesity, physical activity, smoking, alcohol intake, and CRP, low SES yielded only a borderline statistical significance in women (p=0.07), whereas no significant association with diabetes remained in men (p=0.14). After CRP was dropped from the full model, there was no change in the OR obtained for low SES (men: 1.30; 0.92–1.83; women: 1.54; 0.97–2.45). Low SES was not related to prediabetes (IFG, IGT), whereas CRP was significantly associated with diabetes precursors. In conclusion, inflammation appears not to play a major role linking low SES and type 2 diabetes in the elderly population.     

A comparison of the association between socioeconomic position and cardiovascular disease risk factors in three age cohorts of Australian women: findings from the Australian Longitudinal Study on Women's Health

OBJECTIVES: To assess the associations between three measurements of socioeconomic position (SEP) -- education, occupation and ability to cope on available income -- and cardiovascular risk factors in three age cohorts of Australian women. METHODS: Cross-sectional analysis of three cohorts of Australian women aged 18-23, 45-50 and 70-75 years. RESULTS: In general, for all exposures and in all three cohorts, the odds of each adverse risk factor (smoking, obesity and physical inactivity) were lower in the most advantaged compared with the least advantaged. Within each of the three cohorts, the effects of each measurement of SEP on the outcomes were similar. There were, however, some notable between-cohort differences. The most marked differences were those with smoking. For women aged 70-75 (older), those with the highest educational attainment were more likely to have ever smoked than those with the lowest level of attainment. However, for the other two cohorts, this association was reversed, with a stronger association between low levels of education and ever smoking among those aged 18-23 (younger) than those aged 45-50 (mid-age). Similarly, for older women, those in the most skilled occupational classes were most likely to have ever smoked, with opposite findings for mid-age women. Education was also differently associated with physical inactivity across the three cohorts. Older women who were most educated were least likely to be physically inactive, whereas among the younger and mid-age cohorts there was little or no effect of education on physical inactivity. CONCLUSION: These findings demonstrate the dynamic nature of the association between SEP and some health outcomes. Our findings do not appear to confirm previous suggestions that prestige-based measurements of SEP are more strongly associated with health-related behaviours than measurements that reflect material and psychosocial resources.     

Occupation and chronic bronchitis among Chinese women

OBJECTIVE: To examine the association between occupation and chronic bronchitis among a cross section of Chinese women who participated in the Shanghai Women's Health Study. METHODS: Cases were 4873 women who self-reported a physician-diagnosed bronchitis during adulthood. Controls were 9746 women randomly selected from Shanghai Women's Health Study participants and matched with the cases by year of birth and age at diagnosis. Lifetime occupational histories were obtained. Logistic regressions were used to evaluate the association between chronic bronchitis and occupation, adjusting for smoking, education, family income, and concurrent asthma. RESULTS: We observed excess prevalence of bronchitis for textile occupation (odds ratio, OR = 1.09; 95% CI = 1.00-1.18) and industry (OR = 1.11; 95% CI = 1.03-1.19), welders (OR = 1.40; 95% CI = 1.01-1.92), packing and baling workers (OR = 1.39; 95% CI = 1.15-1.68), and warehousing industry (OR = 1.58; 95% CI = 1.08-2.30) We also identified several new associations that may warrant further exploration and confirmation, including employment in some metal fabrication industries, postal and telecommunication industry, and a few white-collar occupations and industries. CONCLUSIONS: Our study indicates that the risk of chronic bronchitis among women may be increased in some occupations and industries.     

Sex differences in the associations of socioeconomic status with undiagnosed diabetes mellitus and impaired glucose tolerance in the elderly population: the KORA Survey 2000

BACKGROUND: Sex differences in the associations of socioeconomic status (SES) with prevalence of undiagnosed diabetes mellitus, impaired glucose tolerance (IGT) and known risk factors of type 2 diabetes mellitus were investigated in an elderly population. METHODS: Oral glucose tolerance tests were carried out in 1354 randomly selected subjects (697 men, 657 women) aged 55-74 years in the population-based KORA Survey 2000, Augsburg, Germany. Odds ratios (ORs) and 95% confidence intervals (CIs) for undiagnosed diabetes or IGT by education, occupation and income were estimated using logistic regression controlling for age, waist circumference, blood pressure, triglycerides, physical activity, smoking and alcohol intake. RESULTS: All three SES variables were significantly inversely related to body mass index, waist circumference and low physical activity in women (P < 0.05). In men, these associations were weaker or absent. Using the lowest category as reference, occupational status was significantly associated with undiagnosed diabetes in women (adjusted OR 0.5; 95% CI 0.3-0.8) after controlling for risk factors in multivariate regression. The OR was also reduced with higher income in women (adjusted OR, diabetes: 0.7; 95% CI 0.5-1.03). Among men, no significant relations of the SES indicators with unknown diabetes were observed. However, the odds of having IGT was lower with higher occupational status in men (adjusted OR 0.7; 95% CI 0.5-0.9). CONCLUSIONS: Undiagnosed type 2 diabetes was related to low SES defined by occupation or income in women only. In men, low occupational status was independently associated with higher IGT risk. Educational level was not related to glucose disorders in both sexes in the elderly population.     

Prevalence and Socio-Demographic Determinants of Overweight and Obesity in a Nigerian Population

Objective

This survey explored prevalence of overweight and obesity and their associations with socio-demographic variables in a Nigerian population.

Methods

This cross-sectional survey involved 1521 adults in Nnewi. Age, sex, educational and occupational status, and BMI were recorded.

Results

Prevalence of overweight was higher in males (32.3%; 95% CI, 29.5%–35.2%) than in females (29.8%; 95% CI, 26.8%–33.0%); the reverse was the case for prevalence of obesity (19.6%; 95% CI, 17.3%–22.2% in males and 36.0%; 95% CI, 32.8%–39.4% in females). Higher odds ratios (ORs) for overweight and obesity were observed in participants aged 41–60 years (OR 2.03; 95% CI, 1.57–2.61 for overweight and OR 4.29; 95% CI, 3.25–5.67 for obesity) and those >60 years (OR 1.72; 95% CI, 1.21–2.43 for overweight and OR 4.21; 95% CI, 2.86–6.19 for obesity) compared to those aged 18–40 years. Female sex was associated with higher ORs for overweight (OR 1.20; 95% CI, 0.96–1.51) and obesity (OR 2.21; 95% CI, 1.73–2.83). Participants with secondary education had marginally higher ORs for overweight (OR 1.15; 95% CI, 0.88–1.51) and obesity (OR 1.17; 95% CI, 0.86–1.59) than those with tertiary education, and so were those with primary education for obesity (OR 1.19; 95% CI, 0.74–1.89) but higher OR for overweight (OR 1.44; 95% CI, 0.98–2.13). Unskilled participants had about the same OR for overweight and obesity as professionals, and while skilled participants had about the same OR for overweight as professionals, their OR for obesity (OR 1.27; 95% CI, 0.67–2.43) was fairly higher than that for professionals.

Conclusions

Prevalence of overweight is higher in males than in females, but the reverse is the case for prevalence of obesity. Older age and female sex are associated with increased risk of overweight and obesity, while working at a skilled occupation is associated with obesity, and tertiary educational attainment is associated with overweight.Key words: determinants, obesity, overweight, prevalence, developing country     

Smoking status and health-related quality of life: as findings from the 2001 Behavioral Risk Factor Surveillance System data

PURPOSE: To examine the relationship between smoking status and health-related quality of life (HRQOL). DESIGN: Our study used a cross-sectional analysis with self-reported data from the 2001 Behavioral Risk Factor Surveillance System (BRFSS). SETTING: United States. SUBJECTS: Subjects were a representative sample of noninstitutionalized adults aged 18 years and older. After excluding respondents who reported being pregnant and for whom smoking status could not be determined, we included 209,031 respondents. MEASURES: Multiple logistic regressions were performed to examine the associations of smoking status with the four HRQOL items, controlling for demographic and health-related characteristics. RESULTS: Current smokers had a higher likelihood of reporting poor general health status compared with nonsmokers and ex-smokers. Compared with nonsmokers, current smokers had a higher likelihood of reporting > or = 14 days of poor physical health (odds ratio [OR] = 1.64, 95% confidence interval [CI] = 1.51-1.77), poor mental health (OR = 1.99, 95% Cl = 1.84-2.16), and activity limitations (OR = 1.80, 95% Cl = 1.63-2.00). Similarly, compared with ex-smokers, current smokers had a higher likelihood of reporting > or = 14 days of poor physical health (OR = 1.30, 95% CI = 1.19-1.42), poor mental health (OR = 1.65, 95% CI = 1.50-1.81), and activity limitations (OR = 1.48, 95% CI = 1.32-1.65). Age, income, and presence of comorbidities also significantly explained variation in HRQOL. CONCLUSIONS: Our study reaffirms the significant association between smoking and HRQOL in a large nationally representative sample. Poor health associated with smoking persists as a major public health problem, and effective preventive and smoking cessation efforts should be undertaken.     

Schul- und Berufsausbildung, beruflicher Status und isch?mische Herzkrankheiten: eine prospektive Studie mit Daten einer gesetzlichen Krankenversicherung in Deutschland

Summary.¶Education and training, occupational position, and ischemic heart disease: a prospective study with data from a statutory German health insurance¶ Objectives: To study associations between education, occupational position, and incidence of ischemic heart disease (ICD-9 410-414).¶ Methods: A cohort of 151471 male and female members of a German statutory health insurance company aged between 25 and 65 years was investigated. The cohort comprised all members between 1987 and 1996. Information on ischemic heart disease was derived from clinical diagnosis. Education, training, and occupational position according to the British Registrar General defined the indicators of social status.¶ Results: After adjustment for age and length of observation period, education and training as well as occupational position were associated with the incidence of ischemic heart disease in both men and women. Whereas a gradient was observed in men regarding education and training (odds ratios (OR): 3.41-6.02) men with lower occupational position had higher risk estimates as compared to the highest occupational status group (OR: 1.73-3.05). Among women a gradient was observed concerning education and training (OR: 1.75-3.78). With regard to occupational status position female members of the highest group showed the lowest risk as compared to the lower status groups (OR: 1.58-2.19).¶ Conclusions: Social inequality in ischemic heart disease morbidity was observed among male and female members of a German statutory health insurance. Findings are of importance for health policy and call for preventive action.     

Body weight dissatisfaction by socioeconomic status among obese, preobese and normal weight women and men: results of the cross-sectional KORA Augsburg S4 population survey

ABSTRACT: BACKGROUND: Body weight dissatisfaction is an important factor in preventing weight gain and promoting weight loss or maintenance. This study focuses on differences in the rates of body weight dissatisfaction among obese, preobese and normal weight women and men by socioeconomic status within a general adult population in Germany. METHODS: Data were analyzed from 4186 adults aged 25 to 74 who participated in a cross-sectional, representative population-based health survey (KORA S4, 1999-2001, Augsburg region/Germany). Body mass was measured anthropometrically and indexed following international standards. Among the 2123 women participating in the survey, 40.3% had a normal weight, 34.9% were preobese, and 24.8% were obese (compared to 25.9%, 51.4% and 22.6% among men, respectively). Body weight dissatisfaction, educational level, household income and occupational status were assessed by computer-aided personal interviewing. An index for socioeconomic status was calculated and categorized into quintiles. Multiple logistic regressions were performed to test for differences in the odds of body weight dissatisfaction across socioeconomic strata in normal weight, preobese and obese groups. Body mass index, age, family status, place of residence and health behaviors were adjusted for. RESULTS: Overall, being dissatisfied with one's body weight was more prevalent in women (48.3%) than in men (33.2%). In the normal weight group, no significant differences in the odds of being dissatisfied were found across socioeconomic groups among women or men. Among preobese men, compared to the lowest socioeconomic stratum, increased odds of being dissatisfied with one's body weight were associated with the highest socioeconomic index group (OR=2.3, 95% CI: 1.4-3.8), middle and high educational level (OR=1.6, 95% CI: 1.1-2.3, and OR=1.9, 95% CI: 1.3-3.7), high income (OR=1.8, 95% CI: 1.2-2.7), and middle and high occupational status (both OR=1.8, 95% CI: 1.2-2.6). Among preobese women, the odds of being dissatisfied were only significantly elevated in those with a middle educational level (OR=1.6, 95% CI: 1.1-2.3). Among obese men, elevated odds were found in the highest socioeconomic index group (OR=3.7, 95% CI: 1.8-7.5) and in those with a high educational level (OR=2.3, 95% CI: 1.3-4.1), high income (OR=2.6, 95% CI: 1.4-4.7), and middle and high occupational status (both OR=2.2, 95% CI: 1.3-3.6). The odds of dissatisfaction among obese women were not associated with socioeconomic status as a whole, but were associated with a high educational level, albeit with a comparatively large confidence interval (OR=3.6, 95% CI: 1.0-12.8). CONCLUSIONS: In Germany, body weight dissatisfaction is more prevalent among obese and preobese men in high socioeconomic status groups, a pattern not found in women. The exception to this is a greater prevalence of dissatisfaction among obese and preobese women with a high educational level (albeit inconsistently). Moreover, there is a social gradient in body weight dissatisfaction, especially in obese men, which may partly explain why obesity is more prevalent in men with low socioeconomic status. It also suggests that they are a target group for obesity care in which body weight satisfaction is an important topic.     

Over-indebtedness as a marker of socioeconomic status and its association with obesity: a cross-sectional study

Background  

The recent credit crunch will have implications for private households. Low socioeconomic status is associated to various diseases. While income, education and occupational status is frequently used in definitions of socioeconomic status, over-indebtedness of private households is usually not considered. Over-indebtedness is currently increasing in high-income countries. However, its association with health – particularly with obesity – remains unknown. Therefore, the aim of this study was to assess an association between over-indebtedness and overweight or obesity.     

Socioeconomic status and multiple myeloma among US blacks and whites

OBJECTIVES: This study examined the relation between socioeconomic status (SES) and risk of multiple myeloma among Blacks and Whites in the United States. METHODS: This population-based case-control study included 573 cases (206 Blacks and 367 Whites) with new diagnoses of multiple myeloma identified between August 1, 1986, and April 30, 1989, and 2131 controls (967 Blacks and 1164 Whites) from 3 US geographic areas. Information on occupation, income, and education was obtained by personal interview. RESULTS: Inverse gradients in risk were associated with occupation-based SES, income, and education. Risks were significantly elevated for subjects in the lowest categories of occupation-based SES (odds ratio [OR] = 1.71, 95% confidence interval [CI] = 1.16, 2.53), education (OR = 1.36, 95% CI = 1.06, 1.75), and income (OR = 1.43, 95% CI = 1.05, 1.93). Occupation-based low SES accounted for 37% of multiple myeloma in Blacks and 17% in Whites, as well as 49% of the excess incidence in Blacks. Low education and low income accounted for 17% and 28% of the excess incidence in Blacks, respectively. CONCLUSIONS: Our results indicate that the measured SES-related factors account for a substantial amount of the Black-White differential in multiple myeloma incidence.     

High Prevalence of Smoking Among Urban-Dwelling Canadian Men Who Have Sex with Men

A small but consistent literature from the United States suggests increased risk for smoking among lesbians and men who have sex with men (MSM). Few studies have investigated smoking among MSM in other countries where different social norms and restrictions on smoking in public apply. We measured smoking behaviours in a convenience sample of urban-dwelling young Canadian MSM (median age 28 years). We compared the prevalence of smoking among MSM with that among other men in British Columbia (BC) using National Population Health Survey data to compute an age-adjusted standardized prevalence ratio (SPR). Independent predictors of smoking among MSM were identified using adjusted odds ratios (OR) with 95% confidence intervals (CI). Smoking during the previous year was reported by twice as many MSM (54.5% of 354) as other men in BC (25.9%) (SPR = 1.94, 95% CI 1.48–2.59), with largest differentials observed among men under 25 years of age. In multivariable analyses, smoking among MSM was significantly associated with younger age (OR 0.94, CI 0.88–1.00 per year), greater number of depressive symptoms (OR 1.12, CI 1.06–1.19 per symptom) and Canadian Aboriginal ethnicity (OR 2.64, CI 1.05–6.60). In summary, MSM in our study were twice as likely to smoke as other men in BC; the greatest differences were observed among the youngest men. The design of effective prevention and cessation programs for MSM will require identification of the age-dependent determinants of smoking initiation, persistence, and attempts to quit.

Injection drug use and HIV/AIDS in China: Review of current situation, prevention and policy implications

There is growing evidence of the public health and community harms associated with crack cocaine smoking, particularly the risk of blood-borne transmission through non-parenteral routes. In response, community advocates and policy makers in Vancouver, Canada are calling for an exemption from Health Canada to pilot a medically supervised safer smoking facility (SSF) for non-injection drug users (NIDU). Current reluctance on the part of health authorities is likely due to the lack of existing evidence surrounding the extent of related harm and potential uptake of such a facility among NIDUs in this setting. In November 2004, a feasibility study was conducted among 437 crack cocaine smokers. Univariate analyses were conducted to determine associations with willingness to use a SSF and logistic regression was used to adjust for potentially confounding variables (p < 0.05). Variables found to be independently associated with willingness to use a SSF included recent injection drug use (OR = 1.72, 95% CI: 1.09–2.70), having equipment confiscated or broken by police (OR = 1.96, 95% CI: 1.24–2.85), crack bingeing (OR = 2.16, 95% CI: 1.39–3.12), smoking crack in public places (OR = 2.48, 95% CI: 1.65–3.27), borrowing crack pipes (OR = 2.50, 95% CI: 1.86–3.40), and burns/ inhaled brillo due to rushing smoke in public places (OR = 4.37, 95% CI: 2.71–8.64). The results suggest a strong potential for a SSF to reduce the health related harms and address concerns of public order and open drug use among crack cocaine smokers should a facility be implemented in this setting.
