Early hormones have been hypothesized to influence both sexual orientation and related childhood sex-typed behaviors. This study examined hormonal influences on activity and playmate preferences in children with congenital adrenal hyperplasia (CAH) age 2.5 to 12 years (24 girls, 19 boys) and their relatives (16 girls, 25 boys). CAH girls preferred boys' toys and activities. They also had greater preference for boy playmates than controls, but this was largely attributable to 4 girls. CAH boys did not differ significantly from controls. Activity and playmate preferences were not related. It was concluded that early androgen has a major effect on childhood activity preferences but only a weak influence on playmate preferences; sex segregation does not arise from sex-typed activity preferences; activity and playmate preferences may be differently predictive of sexual orientation; and hormonal influences on sexual orientation are likely to be complex.

The article presents a framework for understanding the relationship between community garden participation, and the myriad ways gardens and participation lead to emotional, social, and health impacts. Existing empirical research relating community gardens to health behaviors, such as physical activity and diet, and longer-term chronic disease-related outcomes is summarized. The research areas discussed include the effects of community garden participation on individual, social, emotional, and environmental processes; health behaviors including diet and physical activity; and health outcomes such as self-rated health, obesity, and mental health. Other mechanisms through which community gardens may affect population health are described. Applying a multitheoretical lens to explore associations between community garden participation and health enables us to delineate key aspects of gardening that elicit positive health behaviors and multifactorial health assets that could be applied to designing other types of health interventions.
