For a fixed amount of time engaged in physical activity, activity choice may affect body weight differently depending partly on other activities’ displacement. Typical models used to evaluate effects do not directly address these substitutions. An isotemporal substitution paradigm was developed as new analytic model study the time-substitution one for another. In 1991–1997, authors longitudinally examined associations discretionary activities, with varying displacements, 6-year loss...

Background— Among adults, skipping meals is associated with excess body weight, hypertension, insulin resistance, and elevated fasting lipid concentrations. However, it remains unknown whether specific eating habits regardless of dietary composition influence coronary heart disease (CHD) risk. The objective this study was to prospectively examine risk CHD. Methods Results— Eating habits, including breakfast eating, were assessed in 1992 26 902 American men 45 82 years age from the Health...

Although physical activity (PA) has been inversely associated with depressive symptoms, it is not clear whether regular PA and television watching are clinical depression risk. The authors conducted a prospective analysis involving 49,821 US women from the Nurses' Health Study who were free symptoms at baseline (1996). Information on was obtained validated questionnaires completed in 1992, 1994, 1996, 1998, 2000; analyses using cumulative average of (minutes/day) 2-year latency period...

The isotemporal substitution model (ISM) was previously developed as a methodology to study the time-substitution effects of 1 type activity for another in data setting with continuous outcomes. To demonstrate application ISM dichotomous outcome, we prospectively examined associations different activities various displacements depression risk among 32,900 US women from Nurses' Health Study who were free depressive symptoms at baseline (in 1996). During 10-year follow-up, 5,730 incident cases...

OBJECTIVE Central nervous system (CNS) infections cause significant morbidity and mortality often require neurosurgical intervention for proper diagnosis treatment. However, neither the international burden of CNS infection, nor current capacity workforce to treat these diseases is well characterized. The objective this study was elucidate global incidence surgically relevant highlighting geographic areas targeted improvement in capacity. METHODS A systematic literature review meta-analysis...

Previous studies indicate that testosterone (T) is positively correlated with lean mass and inversely fat in men; however, the directionality of these associations, as well association other hormones including estradiol (E2) SHBG, unclear. We examined cross-sectional longitudinal associations E2, T, E2/T ratio body composition among men ages 30 to 79 Boston Area Community Health/Bone Survey. Total, trunk, appendicular were measured by dual-energy x-ray absorptiometry at baseline, weight...
