Comparative StudyTrends in cigarette smoking among adults with HIV compared with the general adult population, United States - 2009-2014.
Smoking increases HIV-related and non-HIV-related morbidity and mortality for persons with HIV infection. We estimated changes in cigarette smoking among adults with HIV and adults in the general U. S. population from 2009 to 2014 to inform HIV smoking cessation programs. ⋯ For most years, non-Hispanic blacks, those with less than high school education, and those living below poverty level were more likely to be current smokers and less likely to quit smoking compared with non-Hispanic whites, those with greater than high school education, and those living above poverty level, respectively. To decrease smoking-related causes of illness and death and to decrease HIV-related disparities, smoking cessation interventions are vital as part of routine care with HIV-positive persons. Clinicians who care for HIV-positive persons who smoke should utilize opportunities to discuss and implement smoking cessation strategies during routine clinical visits.

A prospective investigation of neighborhood socioeconomic deprivation and physical activity and sedentary behavior in older adults.
Neighborhood conditions may have an important impact on physical activity and sedentary behaviors in the older population. Most previous studies in this area are cross-sectional and report mixed findings regarding the effects of neighborhood environment on different types of physical activity. Moreover, little is known about the prospective relationship between neighborhood environment and sedentary behaviors. ⋯ Moreover, people from more deprived neighborhoods were also more likely to engage in prolonged (≥5 h/day) TV viewing (Odds ratio Q5 vs Q1 (95% confidence interval), 1.21 (1.15, 1.27)). In conclusion, neighborhood socioeconomic deprivation is associated with physical activity and sedentary behavior in the older population. These associations may differ for different types of physical activities.

Vascular risk factor burden and new-onset depression in the community.
Depression is associated with an increased likelihood of cardiac events and stroke. We hypothesized that the vascular risk factor burden might itself predispose to both cardiovascular events and depression. Therefore, we examined whether aggregate scores of vascular risk factor burden were associated with the new-onset of depression in the community. ⋯ Results were not explained by interim clinical stroke or cerebral white matter injury. In conclusion, vascular risk factor burden was associated with the new onset of depression. Shared vascular risk factors may contribute to the increased risk of cardiovascular events observed in persons with depression.

Observational StudyBirth weight, gestational age and late adolescent liver function using twin status as instrumental variable in a Hong Kong Chinese birth cohort: "Children of 1997".
Birth weight (BW) is inversely associated with diabetes and liver function in Mendelian Randomization studies. Observationally, lower BW is usually also associated with poorer liver function. However, these studies could be confounded by socioeconomic position. ⋯ Observationally, BW was negatively associated with ALT (-1.23 IU/L, 95% CI -2.16 to -0.30), ALP (-1.72 IU/L, 95% CI -3.43 to -0.01) and higher albumin (-0.23 g/L, 95% CI -0.40 to -0.06). Poor liver function may be a pathway by which the risks of lower BW are actuated. This insight might help identify post-natal targets of intervention to mitigate the adverse health effects of lower birth weight.

The role of physical activity enjoyment in the pathways from the social and physical environments to physical activity of early adolescent girls.
Most girls experience a notable decline in physical activity (PA) in early adolescence, increasing their risk for harmful health outcomes. Enjoyment for PA (i.e., positive feelings toward PA) is a determinant of PA among girls during adolescence and sustained PA throughout adulthood. Previous studies recommended increasing girls' PA enjoyment in order to increase their PA, but did not include environmental-level strategies for how families, schools, or communities do this. ⋯ To PA, there were significant direct effects only from social support from friends (β = 0.15, CI = 0.09, 0.22). To PA enjoyment, there were significant direct effects from social support from family (β = 0.15, CI = 0.08, 0.23), school climate (teachers β = 0.15, CI = 0.10, 0.21 and boys β = 0.15, CI = 0.09, 0.20), and neighborhood environment (β = 0.10, CI = 0.04, 0.17). The findings of this study identified several direct effects of the social and physical environment on PA enjoyment that can begin to inform environmental-level strategies for increasing PA enjoyment among early adolescent girls.
