R and omized controlled trials found a positive correlation for SB with BMI , neck circumference , fat mass , HbA1C , cholesterol and insulin levels , cohort studies additionally for WC , leptin , C-peptide , ApoA1 and Low density lipoprotein and a negative correlation for HDL .
Most studied biomarkers associated with SB were of cardiovascular or metabolic origin .

We conducted a systematic review to investigate the associations between SB and various biomarkers in older adults .
Social relations, physical activity, and well-being in older adults.
BACKGROUND A r and omized controlled trial was conducted to examine : ( a ) the effect of two physical activity modes on changes in subjective well-being ( SWB ) over the course of a 12-month period in older , formerly sedentary adults ( N = 174 , M age = 65.5 years ) and ( b ) the role played by physical activity participation and social support in changes in SWB over time . METHOD Participants were r and omized into either an aerobic activity group or a stretching and toning group . Structural equation modeling was employed to conduct multiple sample latent growth curve analyses of individual growth in measures of SWB ( happiness , satisfaction with life , and loneliness ) over time . RESULTS A curvilinear growth pattern was revealed with well-being significantly improving over the course of the intervention followed by significant declines at the 6-month follow-up . Subsequent structural analyses were conducted showing that frequency of exercise participation was a significant predictor of improvement in satisfaction with life , whereas social relations were related to increases in satisfaction with life and reductions in loneliness . Improvements in social relations and exercise frequency also helped to buffer the declines in satisfaction with life at follow-up . CONCLUSIONS It appears that social relations integral to the exercise environment are significant determinants of subjective well-being in older adults . Findings are discussed in terms of how physical activity environments might be structured to maximize improvements in more global well-being constructs such as satisfaction with life
