Fish consumption among pregnant women in London, Ontario: associations with socio-demographic and health and lifestyle factors

BACKGROUND: Intake of fish and omega-3 fatty acids is inversely related to adverse health outcomes; however, these relationships may be confounded by socio-economic status and health behaviours. This study's purpose was to describe the socio-demographic, health and lifestyle correlates of fish consumption among pregnant women. METHODS: Pregnant women (n=2394) completed a telephone interview between 10-22 weeks' gestation (London, Ontario, 2002-5) containing questions on socio-demographic, health and lifestyle variables; dietary intake was measured using a 106-item validated food-frequency questionnaire. Unadjusted and adjusted risk ratios were obtained using a modified Poisson regression model. RESULTS: Infrequent fish consumption, <1/week, was reported by 32% of women. After adjusting for age and education, infrequent fish consumption was associated with education 相似文献   

Are childhood socio-economic circumstances related to coronary heart disease risk? Findings from a population-based study of older men

BACKGROUND: The independent influence of childhood social circumstances on health in later life remains uncertain. We examined the extent to which childhood socio-economic circumstances are related to the risk of coronary heart disease (CHD) in older British men, taking account of adult social class and behavioural risk factors. METHODS: A socio-economically representative sample of 5552 British men (52-74 years) with retrospective assessment of childhood socio-economic circumstances (father's occupation and childhood household amenities) who were followed up for CHD (fatal and non-fatal) for 12 years. RESULTS: Men whose childhood social class was manual had an increased hazard ratio (HR) 1.34 (95% CI 1.11-1.63)-this effect was diminished when adjusted for adult social class and adult behavioural risk factors (cigarette smoking, alcohol, physical activity and body weight) (HR 1.19; 95% CI 0.97-1.46). Men whose family did not own a car in their childhood were at increased CHD risk even after adjustments for adult social class and behaviours (HR 1.35, 95% CI 1.04-1.75). Men with combined exposure to both childhood and adult manual social class had the highest risk of CHD (HR 1.51; 95% CI 1.19-1.91); this was substantially reduced by adjustment for adult behavioural risk factors (adjusted HR 1.28; 95% CI 0.99-1.65). CONCLUSIONS: Less affluent socio-economic conditions in childhood may have a modest persisting influence on risk of CHD in later life.     

Recent history of the news coverage of violence against women in Spain, 1997-2001

OBJECTIVES: To explore press coverage of violence against women between 1997 and 2001, and to analyze the temporal development of murders due to this cause in Spain and the social context in which these media events take place. METHODS: Quantitative content analyses were performed of 865 news items on violence against women in the Spanish newspapers El País, ABC and El Mundo (1997-2001). Absolute and relative frequencies, and relative risk (RR), 95% confidence intervals (95% CI), were calculated. Crude mortality rates were calculated for violence against women (1998-2003) based on the Register of the Federation of Separated and Divorced Women. RESULTS: Press coverage of violence against women increased, coinciding with dramatic events and political responses to the problem. In this context, mortality from this cause remained constant. News about incidents (65%) were more frequent than news about interventions (35%). In news items in which sex was identified (35% of the total), women (n = 151) and men (n = 150) shared the role of principle information source. Men from law institutions (RR = 1.77; 95% CI, 1.44-2.17) and women from health institutions (RR = 0.39; 95% CI, 0.14-1.08) and associations (RR = 0.33; 95% CI, 0.13-0.81) were more likely to be the main source of information than their counterparts. Men had a higher probability than women of being the main source of information in news about punishment (RR = 1.42; 95% CI, 1.12-1.81). CONCLUSIONS: In a context in which mortality from violence against women remains constant, news about this subject has increased, coinciding with dramatic events and political responses. The main sources of information are politicians of both sexes, men from law institutions, and women from health institutions and associations. Men are the main source of information in news about punishment.     

The joint impact of family history of myocardial infarction and other risk factors on 12-year coronary heart disease mortality.

We investigated the impact of family history of myocardial infarction on 12-year coronary heart disease mortality. Men and women with a family history had an increased risk for coronary heart disease death, irrespective of other risk factors (RR = 1.58; 95% CI = 1.17-2.13 and RR = 2.12; 95% CI = 1.11-4.05, respectively). Women with a family history seemed to be more susceptible to the detrimental effects of smoking; not to the effects of other risk factors. We found no effect modification by family history in men.     

Inequalities in mental health in the working population.

Objectives: To analyze inequalities in mental health in the working population by gender and professional qualifications and to identify psychosocial risk factors and employment conditions related to the mental health of this population. Methods: We performed a cross-sectional study using data from the Barcelona Health Survey 2000. The working population aged 16-64 years (2322 men and 1836 women) was included. Mental health was measured with the General Health Questionnaire (GHQ-12). Adjusted odds ratios (aOR) and their 95% confidence intervals (CI) were calculated by means of multivariate logistic regression models separated by job qualifications and gender. Results: The prevalence of poor mental health ranged from 8% among men working in non-manual occupations to 19% in women working in manual jobs. Women were more likely to report poor mental health status than men, although sex differences were greater among manual workers (aOR = 2.26; 95%CI, 1.68-3.05 for women compared to men in the same group). Differences according to qualifications were found among women only (aOR = 1.58 [95%CI, 1.22-2.05] for women working in manual jobs compared to those working in non-manual jobs), while no differences were found among men according to qualifications. Psychosocial risk factors were associated with mental health: demand was associated in all groups, autonomy only in non-manual occupations, and social support only in the most highly qualified working women. Employment conditions such as working a split shift (working day with a long lunch break) or having a temporary contract were associated with mental health in manual occupations only. Conclusions: Mental health among the working population is related to professional qualifications and gender. Women are at greater risk than men, especially those working in manual occupations. Psychosocial occupational factors are related to mental health status, showing different patterns depending on gender and professional qualifications.     

Consistency between most important reasons for using contraception and current method used: the influence of health care providers

OBJECTIVE: To identify factors related to consistency between women's "most important" reason for using contraception and their current contraceptive method. METHODS: A sample of 433 women completed a written questionnaire on demographics, contraceptive use history and the "most important" reason for using contraception. Women were grouped by whether their current contraceptive method "agreed" or "disagreed" with their "most important" reason for contracepting. Multivariable regression was used to identify factors associated with consistency between stated "most important" reason and current method used ("agreed"). RESULTS: Current contraceptive method was inconsistent with the "most important" reason for using a method in 25% of women. Demographic characteristics and knowledge of contraceptive effectiveness did not differ between the "agreed" and "disagreed" groups. Women using a method consistent with their reason were more likely to have discussed contraception with a health care provider (RR=1.59, 95% CI 1.13-2.25) even after adjusting for source of contraceptive method or source of contraceptive information (RR=1.57, 95% CI 1.10-2.23). CONCLUSION: Contact with a health care provider was the only factor associated with consistency between birth control method and reasons for initiating contraception. This association appears to be independent of knowledge about contraceptive effectiveness.     

Ergogenic supplements and health risk behaviors

OBJECTIVE: Our goals were to determine the prevalence of ergogenic supplement use in a young healthy population and to examine the extent to which supplement use is associated with specific health risk behaviors. STUDY DESIGN: We performed a cross-sectional survey. POPULATION: Individuals entering military service for enlisted training were included. OUTCOMES MEASURED: We recorded previous use of any nutritional ergogenic supplements and self-reported health risk behaviors. RESULTS: Of 550 eligible participants, 499 completed the survey (91% response rate). Individuals who used ergogenic supplements were more likely to drink alcohol (adjusted odds ratio [AOR]=1.8; 95% confidence interval [CI], 1.1-3.1), more likely to drink heavily (AOR=2.4; 95% CI, 1.5-3.9), more likely to ride in a vehicle with someone who had been drinking (AOR=2.2; 95% CI, 1.3-3.6), more likely to drive after drinking (AOR=2.4; 95% CI, 1.3-4.4), and more likely to have been in a physical fight (AOR=1.9; 95% CI, 1.0-3.5), compared with those who had not used supplements. Men were more likely to use supplements than women (P <.001). There were no differences in patterns of supplement use according to age or body mass index. CONCLUSIONS: Our study indicates an association between individuals who use ergogenic nutritional supplements and specific health risk behaviors. This represents an important opportunity for preventive counseling.     

Self-assessed health and mortality: could psychosocial factors explain the association?

BACKGROUND: The single-item question of self-assessed health has consistently been reported to be associated with mortality, even after controlling for a wide range of health measurements and known risk factors for mortality. It has been suggested that this association is due to psychosocial factors which are both related to self-assessed health and to mortality. We tested this hypothesis. METHODS: The study was carried out in a subsample (n = 5667) of the GLOBE-population, a prospective cohort study conducted in the southeastern part of the Netherlands. Data on self-assessed health, sociodemographic variables, various aspects of health status, behavioural risk factors, and a number of psychosocial factors (social support, psychosocial stressors, personality traits, and coping styles) were collected by postal survey and structured interview in 1991, and mortality data were collected between 1991 and 1998. Cox proportional hazards analyses were used to calculate the association between self-assessed health and mortality, before and after controlling for the psychosocial variables. RESULTS: After controlling for sociodemographic variables, various aspects of health status, and behavioural risk factors, self-assessed health is still strongly associated with mortality in our dataset (Relative Risk [RR] of dying for 'poor' versus 'very good' self-assessed health = 3.98; 95% CI: 1.65-9.61). After controlling for the same set of confounders, many of the psychosocial variables are statistically significantly associated with a 'less-than-good' self-assessed health, particularly instrumental social support, long-lasting difficulties, neuroticism, and locus of control. However, only 'disclosure of emotions'-coping style has a statistically significant relationship with mortality. Adding the psychosocial variables to a model already containing self-assessed health does not attenuate the association between self-assessed health and mortality. CONCLUSIONS: We did not find indications that the association between self-assessed health and mortality is due to the psychosocial factors included in this analysis. It seems likely that the unexplained mortality effects of self-assessed health are due to the fact that self-assessed health is a very inclusive measure of health reflecting health aspects relevant to survival which are not covered by other health indicators.     

Pregnancy Intendedness,Maternal Psychosocial Factors and Preterm Birth

Objectives: This study examined associations between reported pregnancy intendedness and several maternal psychosocial factors in relation to preterm birth (<37 weeks' completed gestation). Methods: Women were recruited into a prospective cohort study between the 24th and 29th weeks of pregnancy in central North Carolina from 1996 to 2000. Prior to delivery, participants responded to questions about pregnancy intendedness, life events impacts, depressive symptoms, and coping style. Results: Women who reported not intending their pregnancy had increased odds of reporting low, medium and high levels of perceived stress during pregnancy (OR = 1.4 [95% CI: 1.1, 1.9], OR = 2.2 [95% CI: 1.7, 2.8], and OR = 3.4 [95% CI: 2.6, 4.5], respectively, relative to very low), medium and high levels of depressive symptoms (OR = 2.2 [95% CI: 1.8, 2.9] and OR = 3.1 [95% CI: 2.4, 3.9], respectively), and medium and high levels of several coping styles. Reporting not intending the pregnancy was not associated with increased risk of preterm birth (Risk Ratio [RR] = 1.0, 95% CI: 0.8, 1.1), but reporting the highest quartile of perceived stress (RR = 1.6, 95% CI: 1.1, 2.3) and the highest tertile of distancing coping style (compared with lowest quartile) was associated with preterm birth (RR = 1.4, 95% CI: 1.1, 1.9). Interactions between pregnancy intendedness and the psychosocial variables perceived stress, depression or coping style did not modify the psychosocial variable's associations with preterm birth. Conclusions: Pregnancy intendedness remains an important concept in the reproductive health literature integrally tied to indicators of maternal mental health, but not necessarily to pregnancy outcomes.     

Household risk factors for malaria among children in the Ethiopian highlands

Malaria transmission varies from village to village and even from family to family in the same village. The current study was conducted in northern Ethiopia to identify risk factors responsible for such variations in a hypoendemic highland malaria setting: 2114 children aged < 10 years living in 6 villages situated close to small dams at altitudes from 1775 to 2175 m were monitored. Monthly malaria incidence was determined 4 times over a 1-year period during 1997. Incidence results were then analysed by 14 individual and household factors using Poisson multivariate regression. Among 14 factors analysed, use of irrigated land (rate ratio[RR] = 2.68, 95% CI 1.64-4.38), earth roof (RR = 2.15, 95% CI 1.31-3.52), animals sleeping in the house (RR = 1.92, 95% CI 1.29-2.85), windows (RR = 1.84, 95% CI 1.30-2.63), open eaves (RR = 1.85, 95% CI 1.19-2.88), no separate kitchen (RR = 1.57, 95% CI 1.10-2.23), and 1 sleeping room (RR = 1.52, 95% CI 1.05-2.20), were significantly associated with malaria. The proportion of infection among children exposed to one or no risk factor was 2.1%, increasing with the number of risk factors and reaching 29.4% with 5 or more. Further studies are needed to confirm the importance of particular risk factors, possibly leading to simple health education and control measures that could become part of routine control programmes, implemented with inter-sectoral collaboration.     

Rates and relative risk of hospital admission among women in violent intimate partner relationships

OBJECTIVES: This study assessed the history of hospitalization among women involved in violent intimate relationships. METHODS: In this 1-year retrospective cohort study, female residents of King County, Washington, who were aged 18 to 44 years and who had filed for a protection order were compared with nonabused women in the same age group. Outcome measures included overall and diagnosis-specific hospital admission rates and relative risk of hospitalization associated with abuse. RESULTS: Women known to be exposed to a violent intimate relationship were significantly more likely to be hospitalized with any diagnosis (age-specific relative risks [RRs] ranging from 1.2 to 2.1), psychiatric diagnoses (RR = 3.6, 95% confidence interval [CI] = 2.8, 4.6), injury and poisoning diagnoses (RR = 1.8, 95% CI = 1.2, 2.8), digestive system diseases (RR = 1.9, 95% CI = 1.3, 2.9), and diagnoses of assault (RR = 4.9, 95% CI = 1.1, 22.1) or attempted suicide (RR = 3.7, 95% CI = 1.6, 9.2) in the year before filing a protection order. CONCLUSIONS: This study showed an increased relative risk of both overall and diagnosis-specific hospitalizations among abused women. Intimate partner violence has a significant impact on women's health and use of health care.     

Physical and mental health effects of intimate partner violence for men and women

BACKGROUND: Few population-based studies have assessed the physical and mental health consequences of both psychological and physical intimate partner violence (IPV) among women or men victims. This study estimated IPV prevalence by type (physical, sexual, and psychological) and associated physical and mental health consequences among women and men. METHODS: The study analyzed data from the National Violence Against Women Survey (NVAWS) of women and men aged 18 to 65. This random-digit-dial telephone survey included questions about violent victimization and health status indicators. RESULTS: A total of 28.9% of 6790 women and 22.9% of 7122 men had experienced physical, sexual, or psychological IPV during their lifetime. Women were significantly more likely than men to experience physical or sexual IPV (relative risk [RR]=2.2, 95% confidence interval [CI]=2.1, 2.4) and abuse of power and control (RR=1.1, 95% CI=1.0, 1.2), but less likely than men to report verbal abuse alone (RR=0.8, 95% CI=0.7, 0.9). For both men and women, physical IPV victimization was associated with increased risk of current poor health; depressive symptoms; substance use; and developing a chronic disease, chronic mental illness, and injury. In general, abuse of power and control was more strongly associated with these health outcomes than was verbal abuse. When physical and psychological IPV scores were both included in logistic regression models, higher psychological IPV scores were more strongly associated with these health outcomes than were physical IPV scores. CONCLUSIONS: Both physical and psychological IPV are associated with significant physical and mental health consequences for both male and female victims.     

The impact of including husbands in antenatal health education services on maternal health practices in urban Nepal: results from a randomized controlled trial

Observational studies suggest that including men in reproductive health interventions can enhance positive health outcomes. A randomized controlled trial was designed to test the impact of involving male partners in antenatal health education on maternal health care utilization and birth preparedness in urban Nepal. In total, 442 women seeking antenatal services during second trimester of pregnancy were randomized into three groups: women who received education with their husbands, women who received education alone and women who received no education. The education intervention consisted of two 35-min health education sessions. Women were followed until after delivery. Women who received education with husbands were more likely to attend a post-partum visit than women who received education alone [RR = 1.25, 95% CI = (1.01, 1.54)] or no education [RR = 1.29, 95% CI = (1.04, 1.60)]. Women who received education with their husbands were also nearly twice as likely as control group women to report making >3 birth preparations [RR = 1.99, 95% CI = (1.10, 3.59)]. Study groups were similar with respect to attending the recommended number of antenatal care checkups, delivering in a health institution or having a skilled provider at birth. These data provide evidence that educating pregnant women and their male partners yields a greater net impact on maternal health behaviors compared with educating women alone.     

Hospital use and health status of women during the 5 years following the birth of a premature, low-birthweight infant.

OBJECTIVE: This study examined the health status and hospital use of women after the birth of a premature, low-birthweight infant. METHODS: The subjects were women with infants who participated in a multisite, randomized trial of an early intervention program. The outcomes examined were (1) a maternal health rating of poor or fair (i.e., poorer health) 5 years following delivery and (2) hospital use for a non-pregnancy-related condition. RESULTS: By the fifth year after delivery, 29.7% of the women had been hospitalized for a non-pregnancy-related condition. Women who reported poorer health status (adjusted relative risk [RR] = 2.39; 95% confidence interval [CI] = 1.86, 3.07) or who had asthma (RR = 2.24; CI = 1.31, 3.80) were at greatest risk. After 5 years, 16.9% of the women said they were in poorer health. The number of intervening years in poorer health (1 year, RR = 3.17; CI = 2.04, 4.94; > 1 year, RR = 8.42; CI = 2.20, 12.88), more than 1 year of poverty (RR = 3.28; CI = 1.90, 5.66), obesity (RR = 3.30; CI = 1.44, 7.55), and more than 1 year of employment (RR = 0.55; CI = 0.36, 0.86) were all significantly associated with poorer health. CONCLUSIONS: The continued, substantial morbidity and hospital use of women with a premature, low-birthweight infant has not previously been reported. This observation needs to be verified.     

Self-rated health and its relation to all-cause and cardiovascular mortality in southern Germany. Results from the MONICA Augsburg cohort study 1984-1995

PURPOSE: Studies worldwide show that self-rated health (SRH) is a robust predictor of mortality among the elderly. Only few studies have focussed on a middle-aged population and no such study has been reported from Germany. This study examined the association between SRH and mortality in a middle-aged, population based cohort from Germany, using data from the MONICA (Monitoring Trends and Determinants in Cardiovascular Diseases) Augsburg project. METHODS: The cohort comprises 1521 men and 1498 women aged 35-64; they were followed over 11 years from 1984-1995. Participants provided extensive data on medical conditions and cardiovascular risk factors through interviews and examinations. SRH was assessed globally and in comparison to those of the same age. We estimated relative hazards for mortality from all-causes and cardiovascular disease according to self-ratings of health. RESULTS: Among males the adjusted hazards rate ratio (HRR) of mortality from all-causes was 1.5 (95% CI 1.1-2.2) for combined fair/poor perceived health compared with good/excellent health. Women with fair/poor ratings had no increased risk of dying (HRR = 1.1, 95% CI 0.7-1.9). Men who perceived worse health than persons of the same age showed an adjusted HRR of 1.7 (95% CI 1.0-2.9) as compared to those perceiving better health; in women the adjusted HRR was 1.9 (95% CI 1.0-3.7). The adjusted hazards for dying from cardiovascular diseases in men were 1.3 (95% CI 0.8-2.1) for those perceiving fair/poor and 1.7 (95% CI 0.7-3.7) for those perceiving worse health. CONCLUSIONS: Self-rated health was a predictor of mortality in a middle-aged German population and contains information that is not entirely reflected in underlying medical conditions and risk factors. Self-assessments of health in comparison to individuals of the same age were stronger and more consistently associated with mortality. Global self-ratings of health and self-ratings in comparison to those of the same age may measure slightly different dimensions and the effect of self-rated health may differ among men and women.     

Survey error in measuring socio-economic risk factors of health status: a comparison of a survey and a census

BACKGROUND: Individuals of lower socio-economic status (SES) are less likely to participate in health surveys than individuals of a higher SES. It is, however, not known whether this difference in participation is associated with health status. This study sets out to assess whether a population health survey gives biased estimates of socio-economic inequalities in self-reported health. METHODS: We compared two independent cross-national data collections, a national health interview survey (n = 10,164) and a census (n = 8,491,528), both carried out in Belgium in 2001 and posing the same health question. We computed the prevalence ratios of poor subjective health among socio-economic groups. To estimate the bias, a relative odds ratio (ROR) was computed as the ratio of the survey prevalence ratio to the census prevalence ratio. RESULTS: Less-educated individuals had a lower risk of poor health status in the survey [Prevalence ratio = 1.66, 95% confidence interval (CI): 1.48-1.86] than in the census (Prevalence ratio = 2.23) leading to an underestimation of the risk associated with low education (ROR = 0.74, 95% CI 0.66-0.83). Compared with better-off groups, those who were not working or who were less educated were generally less likely to participate in the survey when they had a poor health status. CONCLUSIONS: Overall, the health survey underestimated the effects of low SES on poor health status, due to selection bias. We conclude that strategies to improve participation among disadvantaged socio-economic groups should be identified.     

Unfairness and health: evidence from the Whitehall II Study

OBJECTIVE: To examine the effects of unfairness on incident coronary events and health functioning. DESIGN: Prospective cohort study. Unfairness, sociodemographics, established coronary risk factors (high serum cholesterol, hypertension, obesity, exercise, smoking and alcohol consumption) and other psychosocial work characteristics (job strain, effort-reward imbalance and organisational justice) were measured at baseline. Associations between unfairness and incident coronary events and health functioning were determined over an average follow-up of 10.9 years. PARTICIPANTS: 5726 men and 2572 women from 20 civil service departments in London (the Whitehall II Study). MAIN OUTCOME MEASURES: Incident fatal coronary heart disease, non-fatal myocardial infarction and angina (528 events) and health functioning. RESULTS: Low employment grade is strongly associated with unfairness. Participants reporting higher levels of unfairness are more likely to experience an incident coronary event (HR 1.55, 95% CI 1.11 to 2.17), after adjustment for age, gender, employment grade, established coronary risk factors and other work-related psychosocial characteristics. Unfairness is also associated with poor physical (OR 1.46, 95% CI 1.20 to 1.77) and mental (OR 1.54, 95% CI 1.19 to 1.99) functioning at follow-up, controlling for all other factors and health functioning at baseline. CONCLUSIONS: Unfairness is an independent predictor of increased coronary events and impaired health functioning. Further research is needed to disentangle the effects of unfairness from other psychosocial constructs and to investigate the societal, relational and biological mechanisms that may underlie its associations with health and heart disease.     

Psychosocial work environment and incidence of severe depressive symptoms: prospective findings from a 5-year follow-up of the Danish work environment cohort study

The authors analyzed the impact of psychosocial work characteristics on the incidence of severe depressive symptoms among 4,133 (49% women) employees from a representative sample of the Danish workforce between 1995 and 2000. Psychosocial work characteristics at baseline included quantitative demands, influence at work, possibilities for development, social support from supervisors and coworkers, and job insecurity. Severe depressive symptoms were measured with the five-item Mental Health Inventory of the 36-item Short-Form Health Survey, with a cutoff point of 52. Women with low influence at work (relative risk (RR) = 2.17, 95% confidence interval (CI): 1.23, 3.82) and low supervisor support (RR = 2.03, 95% CI: 1.20, 3.43) were at increased risk for severe depressive symptoms after exclusion of cases at baseline and adjustment for sociodemographic factors, baseline depression score, and health behaviors. Further adjustments for socioeconomic position did not change the result substantially. Additional analyses showed that a one-standard deviation increase on the influence scale resulted in a 27% decreased risk of severe depressive symptoms. Among men, job insecurity predicted severe depressive symptoms (RR = 2.04, 95% CI: 1.02, 4.07). The findings indicate that the work environment influences the risk of developing severe depressive symptoms and that different factors play a role for men and women.     

Repeated hospitalizations and self-rated health among the elderly: a multivariate failure time analysis

The purpose of this study was to determine to what extent a single measure, self-rated health (SRH), independently predicts long-term hospitalizations due to all causes and to cardiovascular diseases by using both the standard Cox proportional hazards model and a more robust events model. The study cohort consisted of 2,812 elderly subjects residing in New Haven, Connecticut, who were followed from 1982 to 1996 as part of the Established Populations for Epidemiologic Study of the Elderly. After adjustment for baseline risk factors, using the Cox model, a favorable SRH was associated with a significantly lowered risk for a first hospitalization for all causes (risk ratio (RR) = 0.850, 95% confidence interval (CI): 0.774, 0.934) and congestive heart failure (RR = 0.599, 95% CI: 0.426, 0.841) but not for myocardial infarction (RR = 0.882, 95% CI: 0.565, 1.379). With the adjusted robust events model, a positive SRH was associated with a decreased risk in both a first (RR = 0.813, 95% CI: 0.744, 0.889) and a second (RR = 0.870, 95% CI: 0.782, 0.968) hospitalization for any cause. These results indicate that a single measurement of SRH predicts long-term patterns of hospitalization, especially for heart failure, among older adults.     

Risk factors for basal cell carcinoma of the skin in men: results from the health professionals follow-up study.

The authors examined the relation of constitutional factors and sun exposure to risk of basal cell carcinoma of the skin (BCC) in a prospective cohort of 44,591 predominantly Caucasian US male health professionals, 40-75 years of age and free of cancer at enrollment in 1986. During 8 years of follow-up, 3,273 cases of self-reported BCC were documented. The following variables were each associated with an elevated risk of BCC: having red hair; green, hazel, or blue eyes; a tendency to sunburn; and north European ancestry. The lifetime number of blistering sunburns was also positively associated with BCC risk (p trend < 0.0001). Compared with men who as teenagers had been outside less than once a week, men who had been outside weekly (relative risk (RR) = 1.30; 95% confidence interval (CI): 1.14, 1.47) and daily (RR = 1.42; 95% CI: 1.24, 1.63) had an elevated risk of BCC. Living in a region of residence with high solar radiation as an adult was also associated with an increased risk of BCC (RR = 1.48; 95% CI: 1.36, 1.60), whereas living in such a region only in childhood did not increase BCC risk. These results confirm the role of constitutional factors and suggest that adult sun exposure increases BCC risk.
