Do health behaviors cluster together as health lifestyles in adolescence? Are these lifestyles socially patterned? Do these lifestyles impact physical health into adulthood? To answer these questions, we employed data from Waves 1 and 4 of the National Longitudinal Study of Adolescent to Adult Health (n = 7,827). Our latent class analysis revealed four health lifestyles: (a) low risk, (b) moderate risk with substance use, (c) moderate risk with inactivity, and (d) high risk. As suggested by health lifestyle theory, membership in these classes varied according to gender, race-ethnicity, and family structure. Consistent with the life course perspective, regression analyses indicated that those in the high-risk lifestyle tend to exhibit worse health in adolescence and adulthood than those in the low-risk lifestyle. Our findings confirm that socially patterned lifestyles can be observed in adolescence, and these lifestyles are potentially important for understanding the distribution of physical health across the early life course.

Although religious involvement is associated with a number of beneficial health outcomes, few studies have investigated whether religious involvement is associated with breastfeeding behaviors. Our analyses of 2 waves of data from the Fragile Families and Child Wellbeing Study (n = 4 166) indicate that mothers who frequently attend religious services are more likely to initiate breastfeeding than are mothers who never attend services. Understanding religious variations in breastfeeding may allow public health officials to more effectively target vulnerable populations.
