Prevalence of psychological distress, anxiety and depression in rural communities in Australia

OBJECTIVE: To describe the prevalence of psychological distress, depression and anxiety in three Australian rural settings and to identify the levels of risk by gender and age. DESIGN AND SETTING: Three cross-sectional surveys in the Greater Green Triangle area covering the south-east of South Australia (Limestone Coast), and south-west (Corangamite Shire) and north-west (Wimmera) of Victoria. PARTICIPANTS: A total of 1563 people, aged 25-74 years, randomly selected from the electoral roll. MAIN OUTCOME MEASURES: Psychological distress assessed by the Kessler 10, and anxiety and depression assessed by the Hospital Anxiety and Depression Scale. RESULTS: The prevalence of psychological distress was 31% for both men and women with two-thirds reporting moderate and one-third high levels of psychological distress. The prevalence of depression and anxiety was approximately 10%. The highest rate of psychological distress, anxiety and depression occurred in the 45-54 years age group. There were no consistent gender or area differences in the prevalence of psychological distress, depression or anxiety. CONCLUSIONS: A third of the rural population reported psychological distress, with the highest prevalence observed in middle-aged men and women. Thus, health professionals should attend not only to physical health, but also to mental health status in this age group. It is also important to target prevention strategies at the 20% who reported moderate levels of psychological distress in order to prevent the development of more serious conditions.     

Prevalence of chronic head, neck and low back pain and associated factors in women residing in the Autonomous Region of Madrid (Spain)

Objective

To compare the prevalence of chronic headache (CH), chronic neck pain (CNP) and chronic low back pain (CLBP) in the autonomous region of Madrid by analyzing gender differences and to determine the factors associated with each pain location in women in 2007.

Methods

We analyzed data obtained from adults aged 16 years or older (n = 12,190) who participated in the 2007 Madrid Regional Health Survey. This survey includes data from personal interviews conducted in a representative population residing in family dwellings in Madrid. The presence CH, CNP, and CLBP was analyzed. Sociodemographic features, self-perceived health status, lifestyle habits, psychological distress, drug consumption, use of healthcare services, the search for alternative solutions, and comorbid diseases were analyzed by using logistic regression models.

Results

The prevalence of CH, CNP and CLBP was significantly higher (P<0.001) in women (7.3%, 8.4%, 14.1%, respectively) than in men (2.2%, 3.2%, 7.8%, respectively). In women, CH, CNP and CBLP were significantly associated with having ≥3 chronic diseases (OR 7.1, 8.5, 5.8, respectively), and with the use of analgesics and drugs for inflammation (OR: 3.5, 1.95, 2.5, respectively). In the bivariate analysis, the factors associated with pain in distinct body locations differed between men and women.

Conclusions

This study found that CH, CNP and CLBP are a major public health problem in women in central Spain. Women have a higher overall prevalence of chronic pain than men. Chronic pain was associated with a higher use of analgesics and healthcare services.     

Psychological distress and chronic obstructive pulmonary disease in the Renfrew and Paisley (MIDSPAN) study

BACKGROUND: This study examined whether psychological distress might be a predictor of chronic obstructive pulmonary disease (COPD). METHOD: The relation between psychological distress at baseline, measured by the general health questionnaire (GHQ), and chronic bronchitis three years later, as measured by the Medical Research Council (MRC) bronchitis questionnaire and forced expiratory flow in one second (FEV(1)), was examined in 1682 men and 2203 women from the Renfrew and Paisley (MIDSPAN) study. The analyses were run on men and women separately and adjustments were made for age, socioeconomic position, and lung function at baseline (FEV(1)). People with chronic diseases at baseline were then excluded to give a "healthy" baseline cohort. The effect of psychological distress on individual components of the MRC bronchitis questionnaire and FEV(1) was also assessed. RESULTS: In multivariate analyses of the whole cohort baseline psychological distress in women was associated with reduced FEV(1) at follow up (OR 1.31 95% CI 1.0 to 1.73) after adjustment. In women, in the healthy cohort, psychological distress was associated with chronic bronchitis (OR 2.00, 95% CI 1.16 to 3.46), symptoms of bronchial infection (OR 2.14, 95% CI 1.44 to 3.19), symptoms of breathlessness (OR 3.02, 95% CI 1.99 to 4.59), and reduced FEV(1) (OR 1.62, 95% CI 1.13 to 2.32). In men psychological distress predicted symptoms of bronchial infection (OR 2.09, 95% CI 1.28 to 3.42). CONCLUSION: This study supports research suggesting that psychological distress is associated with COPD and shows that psychological distress predicts COPD in women. The robustness of the association and the exact mechanism requires further investigation.     

Associations between short- and long-term unemployment and frequent mental distress among a national sample of men and women

Unemployment has been associated with poor psychologic well-being. Using data from the 2001 Behavioral Risk Factor Surveillance System, we examined relationships between unemployment and frequent mental distress (FMD), defined as 14 or more mentally unhealthy days during the previous 30 days, among 98,267 men and women aged 25-64 years. The age-standardized prevalence of FMD was 6.6% (standard error, 0.14) among employed adults, 14.0% (2.00) among adults unemployed >1 year, and 15.5% (1.18) among those unemployed <1 year. After adjustment, the relative odds of FMD were 2.09 (95% confidence interval [CI] = 1.75-2.50) for adults unemployed <1 year and 1.88 (95% CI = 1.31-2.71) for adults unemployed >1 year compared with employed adults. Similar patterns were observed across gender, race/ethnicity, education, income, and area unemployment groups. Unemployed persons are a population in need of public health intervention to reduce the burden of mental distress. Public health officials should work with government officials to incorporate the health consequences of unemployment into economic policymaking.     

Food accessibility and perceptions of shopping difficulty among elderly people living alone in Japan

Objectives

This aim of this study was to describe the association between shopping difficulty and food accessibility for elderly people living alone in Japan.

Design

A cross-sectoral, multilevel survey was designed to measure shopping difficulty from a food accessibility perspective. The questionnaire was distributed by mail.

Setting

The sample was drawn from seven towns and cities across Japan.

Participants

A geographic information system was used to select the sample: it identified the proximity of elderly people living alone to a supermarket. In total, 2,028 elderly people (725 men and 1,303 women) responded to the questionnaire.

Measurements

The binary dependent variables were shopping is easy/shopping is difficult. A logistic regression analysis adjusting for age and area of residence and using stepwise variable analyses was performed.

Results

The response rate was 58.6%. Overall, 14.6% of elderly men and 21.7% of elderly women consider shopping difficult. The stepwise logistic analysis showed that the food accessibility factors strongly related to shopping difficulty are infrequent car use (women: OR = 6.97), walking difficulties (men: OR = 2.81, women: OR = 3.48), poor eyesight (men: OR = 2.26, women: OR = 1.75), not cooking lunch by oneself (men: OR = 1.63, women: OR = 1.72), not having anyone to help with food shopping (women: OR = 1.45) and living over 1 km away from a supermarket (men: OR = 2.30, women: OR = 2.97).

Conclusion

The study concludes that elderly people’s assessment of shopping difficulty is related to their food accessibility. Important food accessibility aspects include car or motorbike ownership, walking continuously for 1 km, poor eyesight, and having cooking skills and having someone to help with shopping. These physical activity restrictions have a greater influence on shopping difficulty than do either income or proximity to a supermarket.

     

Psychological distress among Kurdish immigrants in Sweden

AIMS: To analyse whether there is an association between sex and poor self-reported health (SRH) and psychological distress in Kurdish immigrants. METHODS: This cross-sectional study is based on a sample consisting of immigrants, aged 27- 60 years, with self-reported Kurdish ethnicity (n=111, men; n=86, women) in Sweden originating from Iran and Turkey. It is based on data collected in 1996 from the first Swedish National Survey on the living conditions of immigrant groups conducted by Statistics Sweden. The prevalences of reporting poor health, sleeping difficulties, general fatigue and anxiety were estimated by sex. The association between sex and SRH and psychological distress was analysed by an unconditional logistic regression model estimating odds ratios (OR) with 95% confidence intervals. The final model was adjusted for age, marital status, education, housing and employment. Immigrant-specific migration-related variables were used to explore possible reasons for the sex differences. RESULTS: Kurdish men and women had a high prevalence of poor SRH and psychological distress. Age-adjusted odds ratios for anxiety were higher in Kurdish women. Sex differences in anxiety remained even when marital status, education, housing and employment were taken into account. CONCLUSIONS: Kurdish men and women report a high prevalence of poor SRH and indicators of psychological distress. Women had a higher risk for anxiety than men. Negative experiences of pre-migration as well as post-migration experiences, such as economic difficulties, preoccupation with the political situation in the home country, perceived discrimination, and feelings of poor control over one's life, were associated with the outcomes.     

Men, women and friends — are there differences in relation to mental well-being?

This is a study on associations between the number of close friends and mental well-being in a nationwide sample of the Finnish general population (n = 1603). Mental well-being was assessed by means of the 12-item General Health Questionnaire. A total of 3% of the sample had no close friends and another 3% had only one. Over half of the sample (52%) reported having five or more friends. The overall prevalence of mental distress was 15% in men and 21% in women. According to multivariate analyses the risk of mental distress was increased in men among those with no friends (odds ratio [OR]: 2.70) and among those who had one (OR: 4.32) or two to four friends (OR: 1.75), as compared with those who had more friends. In women, having only one friend (OR: 2.30), insufficient family support (OR: 1.63) and insufficient support from relatives (OR: 1.77) associated with the risk of mental distress. These results suggest that mental well-being might be promoted if mentally distressed men seeking professional help were supported in building up and maintaining social networks and mentally distressed women were supported in harmonizing their family life. This revised version was published online in June 2006 with corrections to the Cover Date.     

Gender and mental health aspects of living with HIV disease and its longer-term outcomes for UK heterosexual patients

Gender is important in the experience of illness generally and HIV specifically. In this study the authors compare 183 HIV positive women with 76 HIV positive heterosexual men attending United Kingdom HIV clinics on clinical, treatment, and mental health factors. Participants completed a questionnaire on mental health and HIV-related factors. Laboratory measures of HIV viral load and CD4 cell count were obtained at baseline and 6-18 months later. After adjusting for age, employment, and treatment status, men were significantly less likely than women to suffer from high psychological [adjusted odds ratio (OR) = 0.38, 95% confidence interval (CI): 0.17, 0.86] and global symptom distress (adjusted OR = 0.42, 95% CI: 0.19, 0.92). However, men were more likely than women to report having suicidal thoughts (adjusted OR = 1.85, 95% CI: 0.95, 3.58). Relational, sexual behavior, and quality of life factors were similar for men and women. Adherence levels did not differ by gender but were sub-optimal in 56% of patients. Men had significantly lower CD4 counts than women at baseline, but not at follow-up. No differences were observed in the proportions with viral suppression. The groups had generally similar HIV experiences with high psychological distress. Adherence monitoring and gender appropriate psychological support are needed for these groups.     

Psychological distress after employment transitions: the role of subjective financial position as a mediator

OBJECTIVE: To explore the extent to which the mental health effects of transitions into unemployment, or other forms of non-employment, and vice versa, are mediated by financial changes. METHODS: Longitudinal analysis of the British Household Panel Survey from 1991 to 2000. There were 89,264 person-years of observation from 14,686 individuals aged > or =16 years. Main outcome measure was psychological distress measured by the 12-item General Health Questionnaire. RESULTS: Transitions to unemployment were associated with increased risk of psychological distress for men (adjusted odds ratio (OR) 3.15 (95% confidence interval (CI) 2.50 to 3.98)) and for women (OR 2.60 (95% CI 1.97 to 3.43)). Women who left work to look after the family were also more likely to experience psychological distress (OR 1.72 (95% CI 1.45 to 2.05)). A reduced risk of psychological distress was seen for transitions from unemployment to paid employment for men (OR 0.52 (95% CI 0.41 to 0.68)) and for women (OR 0.68 (95% CI 0.69 to 1.40)). Financial difficulty partially mediated these relationships: men who became unemployed and were worse off financially were more likely to experience psychological distress (OR 4.19 (95% CI 3.20 to 5.50)) than men who were not (OR 1.48 (95% CI 0.95 to 2.33)). Conversely, the beneficial health effect for people who left unemployment and became employed was confined to those who were better off financially (OR 0.34 (0.25 to 0.48) for men). CONCLUSIONS: Changes in employment status have both direct and indirect effects, through changes in financial circumstances, on subsequent psychological distress. The results support the view that the direction of causation runs from employment transitions to financial difficulties and psychological distress.     

Psychological distress as a risk factor for coronary heart disease in the Whitehall II Study

BACKGROUND: Psychiatric disorder and psychological distress are increasingly recognized as risk factors for coronary heart disease (CHD). Elucidation of the mechanisms of these associations has implications for prevention. This study aims to confirm the association between psychological distress and CHD and examine if it could be explained by other factors such as health behaviours, social isolation and low control at work. METHODS: A prospective occupational cohort study of London-based civil service employees (Whitehall II Study) with baseline data collected from 1985-1988 with a 5-year follow-up. The participants were male and female middle-aged civil servants working in 20 Government Departments; 73% of eligible employees attended baseline screening. Psychological distress measured by the General Health Questionnaire (GHQ) at baseline was used to predict incidence of self-reported CHD and possible and probable electrocardiographic (ECG) abnormalities during follow-up. RESULTS: In men, baseline psychological distress was associated with an increased incidence of overall self-reported CHD (odds ratios [OR] = 1.83, 95% CI : 1.5-2.3) and ECG abnormalities (OR = 1.51, 95% CI : 1.1-2.1), after adjustment for age, employment grade and length of follow-up. In women, baseline psychological distress was also associated with an increased incidence of CHD (OR = 1.60, 95% CI : 1.2-2.1), but not with ECG abnormalities. Adjustment for health behaviours, marital status, social networks and work characteristics reduced the risks for incident CHD by 12% in men and by 10% in women; for ECG abnormalities these adjustments increased the risk in men by 16% and had little effect in women. CONCLUSIONS: The experience of psychological distress confers increased risk of CHD in men that is not explained by health behaviours, social isolation or work characteristics. The increased risk of CHD associated with psychological distress is not consistently demonstrated in women.     

Factors Associated With Psychological Distress in a Community-Dwelling Japanese Population: The Ohsaki Cohort 2006 Study

Background

In Asia, there has been no population-based epidemiological study using the K6, a 6-item instrument that assesses nonspecific psychological distress.

Methods

Using cross-sectional data from 2006, we studied 43 716 (20 168 men and 23 548 women) community-dwelling people aged 40 years or older living in Japan. We examined the association between psychological distress and demographic, medical, lifestyle, and social factors by using the K6, with psychological distress defined as 13 or more points out of a total of 24 points.

Results

The following variables were significantly associated with psychological distress among the population: female sex, young and old age, a history of serious disease (hypertension, diabetes mellitus, stroke, myocardial infarction, or cancer), current smoking, former alcohol drinking, low body mass index, shorter daily walking time, lack of social support (4 of 5 components), and lack of participation in community activities (4 of 5 components). Among men aged 40 to 64 years, only “lack of social support for consultation when in trouble” and a history of diabetes mellitus remained significant on multivariate analysis. Among men aged 65 years or older, age was not significantly associated with psychological distress, and the significant association with current smoking disappeared on multivariate analysis. Among women aged 40 to 64 years, a history of stroke was not associated with psychological distress. Among women aged 65 years or older, the significant association with current smoking disappeared on multivariate analysis.

Conclusions

A number of factors were significantly associated with psychological distress, as assessed by the K6. These factors differed between men and women, and also between middle-aged and elderly people.Key words: cross-sectional, K6, population-based, psychological distress     

Gender and Mental Health Aspects of Living with HIV Disease and Its Longer-Term Outcomes for UK Heterosexual Patients

Gender is important in the experience of illness generally and HIV specifically. In this study the authors compare 183 HIV positive women with 76 HIV positive heterosexual men attending United Kingdom HIV clinics on clinical, treatment, and mental health factors. Participants completed a questionnaire on mental health and HIV-related factors. Laboratory measures of HIV viral load and CD4 cell count were obtained at baseline and 6–18 months later. After adjusting for age, employment, and treatment status, men were significantly less likely than women to suffer from high psychological [adjusted odds ratio (OR) = 0.38, 95% confidence interval (CI): 0.17, 0.86] and global symptom distress (adjusted OR = 0.42, 95% CI: 0.19, 0.92). However, men were more likely than women to report having suicidal thoughts (adjusted OR = 1.85, 95% CI: 0.95, 3.58). Relational, sexual behavior, and quality of life factors were similar for men and women. Adherence levels did not differ by gender but were sub-optimal in 56% of patients.

Association between diabetes and depression: Sex and age differences

OBJECTIVE: To examine the association between diabetes and the prevalence of depression in different sex and age groups by analysing the cross-sectional data from the National Population Health Survey, conducted in Canada in 1996-1997. STUDY DESIGN: A total of 53072 people aged 20-64 years were included in the analysis. Depression was defined as depression scale 5, based on the Composite International Diagnostic Interview Short-Form (CIDI-SF). Respondents who answered the following question affirmatively were considered to have diabetes: 'do you have diabetes diagnosed by a health professional?'. METHODS: A multiple logistic regression model was used to adjust for potential confounding effects, and a bootstrap procedure was used to take sampling weights and design effects into account. RESULTS: The prevalence of diabetes was much higher in people aged 40-64 years than in people aged 20-39 years (men: 4.7% vs. 0.5%; women: 3.5% vs. 0.8%, respectively). In contrast, people aged 20-39 years had a slightly higher prevalence of depression than those aged 40-64 years (men: 3.1% vs. 2.9%; women: 6.6% vs. 5.4%, respectively). Diabetes was significantly associated with depression in women aged 20-39 years (odds ratio [OR]=2.52, 95% confidence interval [CI]=1.19, 5.32), but not in women aged 40-64 years (OR=1.62, and 95% CI=0.65, 4.06). The association was not significant in both age groups in men, but it tended to be stronger in the younger age group. CONCLUSIONS: The data suggest that diabetes is significantly associated with depression, particularly in young adults.     

Feeling the blues of infertility in a South Asian context: psychological well-being and associated factors among Sri Lankan women with primary infertility

Primary infertility may have a considerable impact on the psychological well-being of women. In the present study, the authors investigated the psychological well-being and its correlates among Sri Lankan women with primary infertility. A total of 177 women with primary infertility were compared with 177 fertile women matched for age and duration of marriage to identify differences in the psychological well-being between the two groups. They were recruited from a prevalence survey conducted in the district of Colombo, Sri Lanka from August 2005 to February 2006. The General Health Questionnaire-30 (GHQ-30) and Mental Health sub-components of the Short Form-36 (SF-36) were used to measure psychological well-being. In addition, infertile women with and without psychological distress were compared to identify the social, marital, treatment, and demographic factors independently associated with psychological distress. A significantly higher proportion of women with primary infertility (66.1%; 95% CI 58.6-73.0%) had psychological distress as compared to fertile women (18.6 %; 95% CI 13.2-25.2%; P < 0.001). After adjustment for confounding factors, infertile women who were psychologically distressed were significantly less educated (OR = 55.3; 95% CI 15.2-201.0), had poor marital communication (OR = 3.5; 95% CI 1.3-9.8), had a higher priority for having children (OR = 4.2; 95% CI 1.3-13.8), and had been previously (OR = 39.1; 95% CI 8.3-185.4) or currently (OR = 11.0; 95% CI 3.0-40.6) investigated/treated for infertility when compared with infertile women without distress. Women with primary infertility reported more distress as compared to fertile women. Psychological distress among infertile women was associated with poorer education, being previously/currently investigated/treated, placing higher importance on having children, and having poor marital communication. The need for psychological intervention targeting infertile women in clinics and community settings is highlighted.     

Determinants of daily smoking in Estonia, Latvia, Lithuania, and Finland in 1994-2002

AIMS: To investigate time trends in the smoking prevalence and the sociodemographic and psychosocial background of smoking in the Baltic countries in comparison with Finland during 1994-2002. METHODS: Differences in daily smoking according to age, education, urbanization, and psychological distress in the Baltic countries and Finland were studied using postal surveys in 1994, 1996, 1998, 2000, and 2002 among adults (20-64 years old) in Estonia (n = 6,271), Latvia (n = 6,106), Lithuania (n = 9,824), and Finland (n = 15,764). RESULTS: In 1994, 1996, 1998, 2000, and 2002 the prevalence of smoking in Estonia, Latvia, Lithuania, and Finland was 47%, 54%, 46%, and 29% among men, and 21%, 19%, 11%, and 19% among women, respectively. Smoking increased among Lithuanian women from 6% in 1994 to 13% in 2002, but decreased among Estonian men and women. Smoking was generally more common among younger individuals, the less educated, and people with distress in all four countries. The odds ratios for smoking for those with low education compared with those with high education were 2.18 (1.69-2.81), 3.32 (2.55-4.31), 2.20 (1.79-2.70) and 2.80 (2.40-3.27) in men, and 1.90 (1.42-2.52). 3.09 (2.28-4.18), 0.86 (0.59-1.26), and 3.00 (2.53-3.55) in women, in Estonia, Latvia, Lithuania, and Finland, respectively. There were indications of increasing educational differences in Latvian men. Smoking was less common among rural women in all countries except Estonia. CONCLUSIONS: Estonia, Latvia, and Finland show characteristics of the "mature" phase of a smoking epidemic, and smoking may not increase in these countries. In Lithuanian women smoking may increase. Smoking may be increasingly unequally distributed in the future in all the studied countries.     

Secular trends in smoking according to educational level between 1986 and 1996: The MONICA study. Catalonia

Objective: To describe trends from 1986-1996 in the prevalence of cigarette smoking between ages 25 to 64 in the MONICA-Catalonia study, according to educational level, and to validate these trends biochemically.Methods: Three cross-sectional surveys in independent random samples of the general population of central Catalonia area carried out in 1986-88, 1990-92 and 1994-96 following the World Health Organization's MONICA protocol. Serum thiocyanate was determined by the Bowler method.Results: A total of 2,571, 2,934 and 3,485 men and women were examined with response rates of 74, 67 and 72% in each survey respectively. The age-adjusted cigarette smoking prevalence decreased in men by 5.1% (95% CI: 1.5 to 8.7) and increased in women by +8.5% (95% CI: +5.6 to +11.4). The prevalence was 46.5% in men and 23.9% in women in 1994-96. The greatest decrease was in men aged 55-64 (9.9%) and the greatest increase was in women aged 35-44 (+14.8%). These trends were confirmed by serum thiocyanate levels, which decreased from 78.9 to 73.9 μmol/l (p = 0.07) in men and increased from 43.7 to 49.8 μmol/l (p < 0.01) in women during the study period. Cigarette smoking increased in less educated women (+10%) and decreased in university women (6%), while cigarette smoking in men decreased irrespective of educational level. Serum thiocyanate levels confirmed the relationship with educational level.Conclusions: The prevalence of cigarette smoking decreased in men between 1986 and 1996 but remained high in 1996. Women showed a pattern of progressive adoption of smoking, especially those with lower educational level.     

Psychological Distress in Hospitalized Patients with Chronic Obstructive Pulmonary Disease

OBJECTIVES: To investigate the prevalence of psychological distress in hospitalized patients with chronic obstructive pulmonary disease (COPD), and to examine possible associations between psychological distress and several sociodemographic variables. METHODS: The Hopkins Symptom Checklist was used to gather data from 92 hospitalized COPD patients. These data were compared with 3,319 respondents aged 45 or over drawn from the 1998 Norwegian Statistics Health Survey. The latter were divided into four groups: respondents with COPD, respondents with other respiratory diseases, respondents with mixed chronic diseases, and a healthy group. RESULTS: The prevalence of psychological distress was found to be 58.7% in the hospitalized COPD patients and 42.9% in the community-based COPD sample. After controlling for sociodemographic variables and current smoking, the results showed a higher risk of psychological distress among hospitalized COPD patients (OR = 23.69; 95% CI: 13.37-41.98) and the community-based COPD sample (OR = 18.16; 95% CI: 8.31-39.68), and with sub-samples with other respiratory diseases (OR = 5.87; 95% CI: 3.82-9.02), and mixed chronic diseases (OR = 3.51; 95% CI: 2.39-5.18). CONCLUSIONS: COPD is associated with a high prevalence of psychological distress in both hospital and community settings. Furthermore, it appears that age, gender, education, marital status, and current smoking status do not substantially mediate the association between the severity of psychological distress and COPD status. The results provide additional evidence of the importance of screening for psychological distress symptoms in both hospitalized and community-based patients with COPD.     

Trends in leisure time and work-related physical activity in the Spanish working population, 1987-2006

Objective

To analyze time trends in the prevalence of leisure time (LTPA) and work-related (WRPA) physical activity between 1987 and 2006 in the Spanish working population.

Methods

We analyzed data taken from the Spanish National Health Surveys for 1987 (n = 29,647), 1993 (n = 20,707), 1995-1997 (n = 12,800), 2001 (n = 21,058), 2003 (n = 21,650), and 2006 (n = 29,478). The main variables were LTPA and WRPA in working adults aged 18-64 years old. We analyzed sociodemographic characteristics, self-perceived health status, lifestyle habits and associated comorbidities using multivariate logistic regression models.

Results

The prevalences of LTPA and WRPA were lower in women than in men (p < 0.05). The practice of LTPA (OR: 1.54, 95%CI: 1.32-1.80 for women; OR = 1.15, 95%CI: 1.02-1.31 for men) and WRPA (OR = 1.73, 95%CI: 1.38-2.19 for women; OR = 1.55, 95%CI: 1.44-1.91 for men) significantly increased from 1987 to 2006. In both genders, the variables associated with a higher likelihood of practicing LTPA were greater age, higher educational level and being an ex- or non-smoker, while negative predictors included being married, worse self-perceived health, and obesity. Factors that increased the probability of reporting WRPA were being married, worse self-rated health status, and sleeping > 8 h per day. The only factor that reduced the probability of reporting WRPA was being an ex- or non-smoker.

Conclusions

We found an increase in LTPA and WRPA in the last 20 years in the Spanish working population. Several factors were associated with a higher or lower likelihood of practicing LTPA or WRPA in this population.     

不孕不育特征与夫妻双方高血压患病风险的关联研究

目的 了解不孕不育夫妇高血压患病现况,探讨不孕不育特征与两性高血压患病风险的关联。方法 本研究依托不孕不育队列开展。不孕不育特征包括是否患不孕不育、不孕不育类型、原因及年限。采用多因素logistic回归模型,分性别分析不孕不育特征与高血压的关联。结果 1 312对不孕不育夫妇中,不孕症女性和不育症男性高血压患病率均显著高于同性别对照组（女:18.6% vs. 13.2%;男:21.5% vs. 14.3%）。女性不孕（OR＝1.64,95％CI:1.13～2.38）、双方共同原因不孕症（OR＝2.15,95％CI:1.11～4.15）、继发性不孕（OR＝1.58,95％CI:1.17～2.13）和不孕年限≥3年（OR＝1.96,95％CI:1.29～2.97）会显著增加女方高血压患病风险;男性不育（OR＝1.79,95％CI:1.29～2.48）、双方共同原因不育症（OR＝1.69,95％CI:1.12～2.56）、继发性不育（OR＝1.52,95％CI:1.00～2.39）和不育年限≥3年（OR＝1.97,95％CI:1.23～3.14）会显著增加男方高血压患病风险。结论 确诊不孕不育、继发性不孕不育、双方共同原因不孕不育及长不孕不育年限是不孕不育夫妇患高血压的风险因素。     

General obesity and central adiposity in a representative sample of Tehranian adults: prevalence and determinants

AIMS: To determine the prevalence and associations of general and central obesity in adults residing in district 13 of Tehran and to examine the associations of obesity with certain factors. DESIGN: Population-based cross sectional study. SETTING: Tehran, the capital of Iran. SUBJECTS: A total of 9984 subjects (4164 men and 5820 women) aged 20-70 years. METHODS: Demographic data were collected and anthropometric indices including weight, height, and waist and hip circumference were measured, according to standard protocols. Dietary intake was assessed by means of two 24-hour dietary recall forms. To determine the prevalence and association of general and central obesity, the suggested cut-off for Tehranian people, adjusted for their age group, was used. A body mass index (BMI) of > or =24 for men and > or =25 for women was used to determine the characteristic of obesity. Central obesity was determined as a waist-hip ratio (WHR) of > 0.86 for men and WHR > or = 0.78 for women. To determine the associations between general and central obesity and other factors, logistic regression was used. RESULTS: The means of BMI, waist circumference (WC), and WHR were 25.8 +/- 4.1 kg/m2, 88.3 +/- 11.4 cm, and 0.91 +/- 0.07 in men and 27.3 +/- 5.4 kg/m2, 87.5 +/- 12.9 cm, and 0.83 +/- 0.08 in women, respectively. Obesity and central obesity were higher in women than in men; 67% vs. 29% for obesity and 93% vs. 74.1% for central obesity, respectively. Illiteracy (OR = 1.65; 95% CI = 1.13-2.41 in men; OR = 1.87, 95% CI = 1.59-2.21 in women), marriage (OR = 3.84, 95% CI = 3.63-4.29 in men; OR = 3.20, 95% CI = 3.63-4.19 in women), and very low physical activity (OR = 1.35, 95% CI = 1.09-1.53 in men; OR = 1.39, 95% CI = 1.10-1.76 in women) were factors associated with obesity. The risk of being centrally obese for men in the fourth quartile of legumes intake was lower than men in other quartiles (p < 0.05). Women in the first quartile of dairy consumption had the highest risk of being generally and centrally obese (OR = 2.16, 95% CI = 1.72-2.48 for general obesity and OR = 3.01, 95% CI = 2.36-3.67 for central obesity). The risk of obesity for women in the fourth quartile of energy and saturated fatty acid consumption was higher than for those in the first quartile (OR = 2.69, 95% CI = 2.39-3.11 for energy and OR = 1.36, 95% CI= 1.10-1.64 for saturated fatty acids). The risk of being centrally obese was higher for women in the first quartile of protein intake compared with women in the fourth quartile (OR = 1.71, 95% CI = 1.02-2.32). CONCLUSIONS: The results from this national population-based study in Iran show high prevalence of obesity in Tehranian adults. The strong associations between obesity and certain life style factors confirm the necessity of multifactorial intervention.
