ABSTRACT We investigated whether exposure to negative aspects of close relationships was associated with subsequent increase in body mass index (BMI) and waist circumference.
Data came from a prospective cohort study (Whitehall II) of 9425 civil servants aged 35 to 55 years at baseline (phase 1: 1985-1988). We assessed negative aspects of close relationships with the Close Persons Questionnaire (range 0-12) at phases 1 and 2 (1989-1990). We measured BMI and waist circumference at phases 3 (1991-1994) and 5 (1997-1999). Covariates at phase 1 included gender, age, marital status, ethnicity, BMI, employment grade, smoking, physical activity, fruit and vegetable consumption, and common mental disorder.
After adjustment for sociodemographic characteristics and health behaviors, participants with higher exposure to negative aspects of close relationships had a higher likelihood of a 10% or greater increase in BMI and waist circumference (odds ratios per 1-unit increase 1.08 [95% confidence interval (CI) =1.02, 1.14; P = .007] and 1.09 [CI = 1.04, 1.14; P ≤ .001], respectively) as well as a transition from the overweight (25 ≤ BMI  < 30) to the obese (BMI  ≥ 0) category.
Adverse social relationships may contribute to weight gain.

    ABSTRACT: This study tests the inclusion of social support as a distinct exogenous variable in the Biobehavioral Family Model (BBFM). The BBFM is a biopsychosocial approach to health that proposes that biobehavioral reactivity (anxiety and depression) mediates the relationship between family emotional climate and disease activity. Data for this study included married, English-speaking adult participants (n = 1321; 55% female; M age = 45.2 years) from the National Comorbidity Survey Replication, a nationally representative epidemiological study of the frequency of mental disorders in the U.S. Participants reported their demographics, marital functioning, social support from friends and relatives, anxiety and depression (biobehavioral reactivity), number of chronic health conditions, and number of prescription medications. Confirmatory factor analyses supported the items used in the measures of negative marital interactions, social support, and biobehavioral reactivity, as well as the use of negative marital interactions, friends’ social support, and relatives’ social support as distinct factors in the model. Structural equation modeling indicated a good fit of the data to the hypothesized model (χ2 = 846.04, p = .000, SRMR = .039, CFI = .924, TLI = .914, RMSEA = .043). Negative marital interactions predicted biobehavioral reactivity (β = .38, p<.001), as did relatives’ social support, inversely (β = -.16, p<.001). Biobehavioral reactivity predicted disease activity (β = .40, p<.001) and was demonstrated a significant mediator through tests of indirect effects. Findings are consistent with previous tests of the BBFM with adult samples, and suggest the important addition of family social support as a predicting factor in the model.

    ABSTRACT: The extent to which social relationships influence cognitive aging is unclear. In this study, we investigated the association of midlife quality of close relationships with subsequent cognitive decline. Participants in the Whitehall II Study (n = 5,873; ages 45-69 years at first cognitive assessment) underwent executive function and memory tests 3 times over a period of 10 years (1997-1999 to 2007-2009). Midlife negative and positive aspects of close relationships were assessed twice using the Close Persons Questionnaire during the 8 years preceding cognitive assessment. Negative aspects of close relationships, but not positive aspects, were associated with accelerated cognitive aging. Participants in the top third of reported negative aspects of close relationships experienced a faster 10-year change in executive function (-0.04 standard deviation, 95% confidence interval: -0.08, -0.01) than those in the bottom third, which was comparable with 1 extra year of cognitive decline for participants aged 60 years after adjustment for sociodemographic and health status. Longitudinal analysis found no evidence of reverse causality. This study highlights the importance of differentiating aspects of social relationships to evaluate their unique associations with cognitive aging.

    ABSTRACT: Chronic psychosocial stress has been proposed as a risk factor for the development of the metabolic syndrome (MES). This review gives a systematic overview of prospective cohort studies investigating chronic psychosocial stress as a risk factor for incident MES and the individual elements of MES. Thirty eight studies were included. An association between chronic psychosocial stress and the development of MES was generally supported. With respect to weight gain the prospective studies found etiological roles for non-work stress (NWS) while the studies on work-related stress (WS) showed conflicting results. Too few studies on psychosocial stress as a risk factor for dyslipidemia were available to draw a conclusion. With respect to type 2 diabetes mellitus (DM2) the prospective studies support NWS as a risk factor among men, but not among women, while WS was not supported as a risk factor for incident DM2 among neither men nor women. With respect to hypertension the studies on NWS showed conflicting results, while WS was generally not supported as a risk factor for incident hypertension. In conclusion chronic psychosocial stress is supported as an etiological factor for the development of MES. NWS seems to be a risk factor for weight gain, not specified on genders, and for DM2 among men. WS is generally not supported as a risk factor for neither weight gain, incident DM2 nor hypertension. Overall the studies are heterogeneous why more research on the etiological role of psychosocial stress is needed.
