Impotence and its medical and psychosocial correlates: results of the Massachusetts Male Aging Study.
TLDR
It is concluded that impotence is a major health concern in light of the high prevalence, is strongly associated with age, has multiple determinants, including some risk factors for vascular disease, and may be due partly to modifiable para-aging phenomena. Expand
Age trends in the level of serum testosterone and other hormones in middle-aged men: longitudinal results from the Massachusetts male aging study.
TLDR
The paradoxical finding that longitudinal age trends were steeper than cross-sectional trends suggests that incident poor health may accelerate the age-related decline in androgen levels. Expand
Outcomes of a Field Trial to Improve Children's Dietary Patterns and Physical Activity: The Child and Adolescent Trial for Cardiovascular Health (CATCH)
TLDR
The CATCH intervention was able to modify the fat content of school lunches, increase moderate-to-vigorous physical activity in PE, and improve eating and physical activity behaviors in children during 3 school years. Expand
Incidence of erectile dysfunction in men 40 to 69 years old: longitudinal results from the Massachusetts male aging study.
TLDR
The incidence of erectile dysfunction in men 40 to 69 years old in Massachusetts was estimated during an average 8.8-year followup, and how risk varied with age, socioeconomic status and medical conditions was determined. Expand
Prevalence of vitamin D deficiency among healthy adolescents.
TLDR
Vitamin D deficiency was present in many US adolescents in this urban clinic-based sample and the prevalence was highest in African American teenagers and during winter, although the problem seems to be common across sex, season, and ethnicity. Expand
School physical education: effect of the Child and Adolescent Trial for Cardiovascular Health.
TLDR
The implementation of a standardized curriculum and staff development program increased children's MVPA in existing school PE classes in four geographic and ethnically diverse communities, meeting the established Year 2000 objective of 50. Expand
Age, disease, and changing sex hormone levels in middle-aged men: results of the Massachusetts Male Aging Study.
TLDR
Subgroup analyses suggested that obese subjects might be responsible for much of the group difference in androgen level, and serum concentrations of estrogens and cortisol did not change significantly with age or differ between groups. Expand
Validation of interviewer- and self-administered physical activity checklists for fifth grade students.
TLDR
It is concluded that both self-report forms received moderate support for their validity in all gender and ethnic subgroups, and the self-administered format is more cost-effective. Expand
Erectile dysfunction and coronary risk factors: prospective results from the Massachusetts male aging study.
TLDR
Erectile dysfunction and coronary heart disease share some behaviorally modifiable determinants in men who, like the Massachusetts Male Aging Study, are free of manifest ED or predisposing illness. Expand
Testosterone, sex hormone-binding globulin, and the development of type 2 diabetes in middle-aged men: prospective results from the Massachusetts male aging study.
TLDR
The prospective findings are consistent with previous, mainly cross-sectional reports, suggesting that low levels of testosterone and SHBG play some role in the development of insulin resistance and subsequent type 2 diabetes. Expand
