Metabolic syndrome is associated with self-perceived depression.

ABSTRACT: OBJECTIVE: To study the association between metabolic syndrome (MetS) and self-perceived depression. DESIGN: A cross-sectional community-based study. SETTING: Semi-rural community of Lapinlahti in eastern Finland in 2005. SUBJECTS: A total of 416 subjects in eight adult birth cohorts (55%) with complete Beck Depression Inventory (BDI-21) questionnaire data. MAIN OUTCOME MEASURES: The values of the 21 BDI items and the BDI-21 total score with a cut-off point of 14/15 were used to study the association between MetS and depression. National Cholesterol Education Programme (NCEP) 2005 criteria were used for MetS classification. RESULTS: The total BDI-21 score was significantly higher in the subjects with MetS than in the subjects without MetS (p=0.020). Men with MetS were significantly worse off than men without MetS in the BDI-21 items of irritability (p=0.008), work inhibition (p=0.008), fatigability (p=0.037), weight loss (p=0.045), and loss of libido (p=0.014), while women were only so on the item of loss of libido (p=0.007). In a logistic regression analysis using a BDI-21 cut-off point of 14/15 adjusted for age, marital status, vocational education, and working status, significant association was retained between perceived depression and elevated blood glucose among men (OR=1.697) and large waist circumference among women (OR=1.066). CONCLUSION: Elevated plasma glucose in men and central obesity in women are associated with self-perceived depression. This co-occurrence deserves attention in clinical practice.

Project description:BACKGROUND:Neighborhood environment, such as green vegetation, has been shown to play a role in coping with stress and mental ill health. Yet, epidemiological evidence of the association between greenness and mental health is inconsistent. METHODS:We examined whether living in green space is associated with self-perceived stress, depressive and anxiety symptoms in a nationally representative, longitudinal sample of community-dwelling older adults (N = 4118; aged 57-85 years) in the United States. We evaluated perceived stress, depression and anxiety symptoms using the Cohen's Perceived Stress Scale, the Center for Epidemiological Studies - Depression, and the Hospital Anxiety and Depression Scale - anxiety subscale, respectively. Greenness was assessed for each participant using the Normalized Difference Vegetation Index at 250-m resolution, as well as a buffer of 1000-m. We conducted longitudinal analyses to assess the associations between greenness and mental health upon adjusting for confounders (e.g., education), and to examine potential mediation and effect modification. RESULTS:An interquartile range (0.25 point) increase in contemporaneous greenness was significantly associated with 0.238 unit (95% CI: - 0.346, - 0.130) and 0.162 unit (95% CI: - 0.271, - 0.054) decrease in the perceived stress in base and multivariable models, respectively. The magnitude of the association was similar or even stronger when examining summer (- 0.161; 95% CI: - 0.295, - 0.027) and annual average of greenness (- 0.188; 95% CI: - 0.337, - 0.038), as well as greenness buffer of 1000-m. The greenness-stress association was partially mediated by physical activity (15.1% mediated), where increased greenness led to increased physical activity and less stress, and by history of respiratory diseases (- 3.8% mediated), where increased greenness led to increased respiratory disease and more stress. The association was also significantly modified by race, social support, physical function, socioeconomic status, and region. While greenness was not significantly associated with anxiety and depressive scores across all participants, significant inverse associations were found for Whites participants, and for individuals with higher socioeconomic status, who were physically active, as compared to their counterparts. CONCLUSION:We found a direct association of greenness with perceived stress among older adults, and an indirect association mediated through physical activity and respiratory disease history. Our study findings warrant further examination of the mediation and modification of the greenness-mental health association.
