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
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
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
Sleep duration as a risk factor for the development of type 2 diabetes.
TLDR
Short and long sleep durations increase the risk of developing diabetes, independent of confounding factors, and sleep duration may represent a novel risk factor for diabetes. Expand
Prevalence and incidence of androgen deficiency in middle-aged and older men: estimates from the Massachusetts Male Aging Study.
TLDR
Estimates of the crude and age-specific prevalence and incidence rates of androgen deficiency in a randomly sampled population-based cohort of middle-aged and older men and projections for the number of cases in the 40- to 69-yr-old U.S. male population were computed. Expand
Prevalence of symptomatic androgen deficiency in men.
TLDR
Prevalence of symptomatic androgen deficiency in men 30 and 79 yr of age is 5.6% and increases substantially with age, projection of these estimates to the year 2025 suggests that there will be as many as 6.5 million American men ages 30-79 yr with symptomaticandrogen deficiency, an increase of 38% from 2000 population estimates. 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
Prevalence of foot and ankle conditions in a multiethnic community sample of older adults.
TLDR
Significant racial/ethnic differences were found for the prevalence of most toe deformities and flat feet, as well as for corns and calluses, fungal signs, edema, ankle joint pain, tenderness to palpation, and sensory loss in older adults. Expand
