The REasons for Geographic And Racial Differences in Stroke (REGARDS) Study is a national, population-based, longitudinal study of 30,000 African-American and white adults aged > or =45 years. The objective is to determine the causes for the excess stroke mortality in the Southeastern US and among African-Americans. Participants are randomly sampled with recruitment by mail then telephone, where data on stroke risk factors, sociodemographic, lifestyle, and psychosocial characteristics are collected. Written informed consent, physical and physiological measures, and fasting samples are collected during a subsequent in-home visit. Participants are followed via telephone at 6-month intervals for identification of stroke events. The novel aspects of the REGARDS study allow for the creation of a national cohort to address geographic and ethnic differences in stroke.

PURPOSE: Previous studies among young pitchers have focused on the frequency and description of elbow injuries. The purpose of this study was to evaluate the frequency of elbow and shoulder complaints in young pitchers and to identify the associations between pitch types, pitch volume, and other risk factors for these conditions. METHODS: A prospective cohort study of 298 youth pitchers was conducted over two seasons. Each participant was contacted via telephone after each game pitched to identify arm complaints. Generalized estimating equations were used to assess associations between arm complaints and independent variables. RESULTS: The frequency of elbow pain was 26%; that of shoulder pain, 32%. Risk factors for elbow pain were increased age, increased weight, decreased height, lifting weights during the season, playing baseball outside the league, decreased self-satisfaction, arm fatigue during the game pitched, and throwing fewer than 300 or more than 600 pitches during the season. Risk factors for shoulder pain included decreased satisfaction, arm fatigue during the game pitched, throwing more than 75 pitches in a game, and throwing fewer than 300 pitches during the season. CONCLUSION: Arm complaints are common, with nearly half of the subjects reporting pain. The factors associated with elbow and shoulder pain were different, suggesting differing etiologies. Developmental factors may be important in both. To lower the risk of pain at both locations, young pitchers probably should not throw more than 75 pitches in a game. Other recommendations are to remove pitchers from a game if they demonstrate arm fatigue and limit pitching in nonleague games.

OBJECTIVES: To describe the incidence of cardiovascular risk factors, or race-related disparities in incidence, across the age spectrum in adults. DESIGN: Longitudinal cohort. SETTING: National sample. PARTICIPANTS: Community-dwelling black and white adults recruited between 2003 and 2007. MEASUREMENTS: Incident hypertension, diabetes mellitus, dyslipidemia and atrial fibrillation over 10 years of follow-up in 10,801 adults, stratified according to age (45-54, 55-64, 65-74, ≥75). RESULTS: There was no evidence (P ≥ .68) of an age-related difference in the incidence of hypertension for white men (average incidence 38%), black men (48%), or black women (54%), although for white women incidence increased with age (45-54, 27%; ≥75, 40%). Incidence of diabetes mellitus was lower at older ages for white men (45-54, 15%; ≥75, 8%), black men (45-54, 29%; ≥75, 13%), and white women (45-54, 11%; ≥75, 4%), although there was no evidence (P = .11) of age-related changes for black women (average incidence 21%). For dyslipidemia, incidence for all race-sex groups was approximately 20% for aged 45 to 54 but approximately 30% for aged 54 to 64 and 65 to 74 and approximately 22% for aged 75 and older. Incidence of atrial fibrillation was low at age 45 to 54 (<5%) but for aged 75 and older was approximately 20% for whites and 11% for blacks. The incidence of hypertension, diabetes mellitus, and dyslipidemia was higher in blacks across the age spectrum but lower for atrial fibrillation. CONCLUSION: Incidence of risk factors remains high in older adults. Blacks have a higher incidence of hypertension, diabetes mellitus, and dyslipidemia after age 45, underscoring the ongoing importance of prevention of all three conditions in mid- to later life.

CONTEXT: The National Survey of Family Growth (NSFG) classifies pregnancies as intended, mistimed or unwanted. However, these categories could be too broad, as a woman's feelings about a pregnancy, her health behaviors during pregnancy and thus her pregnancy outcomes may vary according to whether her pregnancy is moderately or seriously mistimed. These relationships have not yet been explored. METHODS: Data from the 1995 NSFG were examined to assess associations between pregnancy mistiming and maternal characteristics. Descriptive and multivariate analyses were conducted of the extent of mistiming for each maternal characteristic. Chi-square and F-tests were used to examine the associations between a pregnancy's intendedness--according to a four-category classification--and maternal characteristics, maternal happiness ratings, maternal behaviors and pregnancy outcomes. RESULTS: Fifty-five percent of mistimed pregnancies were mistimed by 24 months or less, 32% were mistimed by 25-60 months and 13% were mistimed by more than 60 months. According to multivariate analyses, pregnancies among younger women, never-married women and black women were mistimed by significantly more months than those among other women. The distribution of moderately mistimed pregnancies differed significantly from those of both seriously mistimed and unwanted pregnancies according to most maternal characteristics; there were few differences between intended and moderately mistimed pregnancies, and between seriously mistimed and unwanted pregnancies. CONCLUSIONS: Mistiming is not a unitary construct. Its extent is associated with maternal characteristics and behaviors. Future research on pregnancy intention should examine the extent of mistiming and consider alternatives to traditional definitions of intendedness.
