Correlates of strength training in older rural African American and Caucasian women

This study examined factors influencing strength training (ST) in two convenience samples of older rural women. Focus group (FG) participants were 23 Caucasian and 16 African American women aged 67.5 +/- 9.2 years. Survey participants were 60 Caucasian and 42 African American women, aged 70.59 +/- 9.21 years. FG participants answered questions about the risks, benefits, and barriers to ST. Survey participants completed measures of demographics, physical activity (including ST), depression and stress, decisional balance for exercise (DBE), barriers to PA, and social support (SS). Regression modeling examined correlates of ST. FG participants identified physical health gains and improved appearance as ST benefits. African American women also included mental health benefits and "feeling good". Both Caucasian and African American groups named physical health problems as risks of ST. Caucasian women identified time constraints, lack of ST knowledge, physical health problems, lack of exercise facilities, and the cost of ST as barriers. African American women cited being "too tired", physical health problems, lack of support, and other family and work responsibilities. The linear regression model explained 23.2% of the variance in hours per week of ST; DBE and family SS were independent positive correlates. This study identified correlates to participation in ST in older rural women and provides a basis for developing ST interventions in this population.     

Correlates of physical activity among African American and white women

Objective: To compare potential correlates of physical activity between African American and white women. Methods: A random-digit-dialed telephone survey was conducted in central South Carolina. Bivariate and multivariate analyses focused on women aged 18+ (N = 1176). Results: African American women reported greater maintenance of sidewalks and public parks than did white women, who reported higher physical activity, exercise self-efficacy, access to indoor walking facilities, and knowledge of mapped-out walking routes. Exercise self-efficacy was the only significant correlate of physical activity among both African American and white women. Conclusions: Self-efficacy was a robust cross-sectional correlate of physical activity in women.     

Correlates of Television Viewing Among African American and Caucasian Women

This study explores the associations between time spent watching television and physical activity, selected eating behaviors, and quality of life variables among 189 African American and Caucasian women aged 18–60 years. Data were collected via a cross-sectional, random-digit-dialed telephone survey. Seventy-two percent and 46% of women reported to “always, often, or sometimes” eating or overeating while watching television, respectively. Significant associations with television time per week included: eating meals or snacks while watching television, number of days per month feeling depressed, number of days per month feeling anxious, self-rated health, and BMI. Results contribute to recent studies finding associations between television viewing, body mass index, and health; and suggest potential points for intervention.     

Correlates of consistent condom use among HIV-positive African American women.

INTRODUCTION: African American women are the fastest growing group at risk of contracting HIV, as over 68% of women diagnosed with HIV are African American. The present study used social-cognitive theory and the theory of gender and power to identify correlates of consistent condom use among African American women living with HIV. METHODS: We recruited 366 women, 18-50 years of age and living with HIV from several HIV/AIDS clinics in the southeastern United States. The majority of women, 84.2% (N = 308), were African American. Women completed a baseline interview assessing sociodemographic, psychosocial, and partner-related factors potentially associated with consistent condom use, defined as reported use of condoms during every vaginal sex episode with a male sexual partner in the past 30 days. RESULTS: Among those HIV-positive African American women reporting use of a condom in the past 30 days (n = 234, 70%), consistent condom use was reported by 67.1% of women. This rate was lower (51.6%) among women having an HIV-positive male sexual partner; the rate was higher (74.1%) among women having an HIV-negative male sexual partner. Compared to women who were inconsistent condom users, women with HIV were more likely to use condoms if they: had high partner communication self-efficacy (OR = 7.77, 95% CI = 3.3-18.6, p = .001), had a HIV-negative male sex partner (OR = 4.62, 95% CI = 1.9-11.5, p = 0.001), had low partner-related barriers to condom use (OR = 4.68, 95% CI = 1.8-12.2, p = 0.001), and had perceived peer norms supportive of condom use (OR = 2.38, 95% CI = 1.0-5.7, p = 0.03). CONCLUSION: These findings suggest that HIV interventions may enhance consistent condom use among African American women living with HIV by targeting women's self-efficacy to communicate with their partners and women's perception of personal and partner-related barriers to condom use.     

Binge eating among African American and Caucasian bariatric surgery candidates

Bariatric surgery is an increasingly utilized treatment for severe obesity, especially among women. Although African American women have high rates of severe obesity, most research investigating psychological correlates of obesity has been conducted with Caucasians. This study examined the characteristics of African American women seeking bariatric surgery, and ethnic differences in BED rates and correlates of binge eating. Finally, we examined whether the association between psychological factors associated with binge eating was moderated by ethnicity. Results indicated that African American women had higher BMIs, higher self esteem, and less depression than Caucasians. There were no differences in rates of binge eating or BED. Both depression and self esteem accounted for unique variance in binge eating; however, these relationships were not moderated by ethnicity. These results further highlight African Americans' vulnerability to EDs, and suggest that depression and low self esteem are equally relevant to binge eating in African American and Caucasian women.     

Correlates of self-efficacy for physical activity in African American women

This study examined the correlates of self-efficacy for physical activity in African American women. In bivariate analyses, self-efficacy was higher among women reporting fewer social role constraints, more positive perceptions of physically active women, more positive sense of community, better perceived health, and higher levels of physical activity. In a simultaneous multivariate model, more positive perceived health status (p = .001), higher physical activity level (p = .007), and lower social role constraint (p = .02) were independently associated with higher self-efficacy. Thus, physical activity interventions for African-American women should include strategies to decrease social role constraint and offer safe activities for women with health conditions hindering physical activity.     

The relationship between eating behaviors and obesity in African American and Caucasian women

The primary goal of this study was to determine the relevance of four self-reported eating behaviors (eating before bedtime, eating between meals, feeling hungry within 3 h of eating, and eating beyond satiation) as risk factors for overweight and obesity. The sample consisted of 35- to 49-year-old, premenopausal African American (n=580) and Caucasian (n=398) women, randomly selected from the membership of a large urban prepaid health plan. Eating beyond satiation was the only behavior associated with body mass index (BMI). The odds of becoming obese increased 6-fold for Caucasian women and 15-fold for African American women who ate beyond satiation everyday compared to those who rarely or never ate beyond satiation. Additionally, eating beyond satiation was also the only eating behavior associated with the age of obesity onset. Focusing on this eating behavior in weight loss programs may be important.     

Spirituality in African American and Caucasian women with end-stage renal disease on hemodialysis treatment

This reanalysis of data from a previous investigation in the United States was conducted to compare spiritual well-being scores of African American (n = 31) and Caucasian (n = 27) women on hemodialysis for end-stage renal disease (ESRD). Women, aged 24 to 79, completed the spiritual well-being (SWB) scale and other instruments. Results indicated a strong trend for African American women to score higher on religious well-being than Caucasian women. Comparisons of SWB item scores indicated areas of spiritual strengths for African American women: perceptions of God's concern for them, God's help with loneliness, fulfilling relationship with God, satisfaction with life, and sense of life's purpose. These findings have multidisciplinary implications for factors that may mitigate the illeffects of ESRD.     

Predictors of leisure-time physical activity among African American women

OBJECTIVES: To examine the extent to which social support and self-efficacy were related to the duration of leisure-time physical activity in a sample of African American women. METHODS: Two hundred forty African American women completed a 45-item questionnaire at community health centers and churches. RESULTS: Mean weekly physical activity was found to be 88 minutes. Self-efficacy (P < or = 0.01) and frequency of social support from friends (P < or = 0.01) were found to be significant predictors for physical activity and accounted for 23.7% of the variance. CONCLUSIONS: Physical activity interventions for Black women must build on the constructs of self-efficacy and friends' social support.     

Perceptions of hormone replacement therapy among African American women

Hormone replacement therapy (HRT) is commonly prescribed for women to relieve symptoms associated with menopause. The medical community does not uniformly recommend HRT, and ethnic and cultural differences may influence a woman's decision to request and adhere to it. Thirty-eight African American women were enrolled in a qualitative study to investigate beliefs, attitudes, and knowledge about HRT. Data collected from six focus groups were part of Ethnicity, Needs, and Decisions of Women (ENDOW), a multisite project investigating decision making and hysterectomy. Participants, age 30 to 65 years, were recruited from community agencies and public health clinics. The women were aware of the medical indications for HRT and its risks and benefits. Although a majority of participants were past or current users, they expressed reservations about the use of HRT and wanted a better dialogue with health care providers, including information about alternative treatments.     

Early adult characteristics and mortality among inner-city African American women

OBJECTIVES: This study examined predictors of longevity in a cohort of inner-city African American women. METHODS: Data were derived from a cohort study of inner-city African American mothers whose median age in 1966 was 31 years. Analyses involved single-decrement life tables and pooled logistic regression. RESULTS: Giving birth for the first time before age 25 and having at least a high school education predicted longevity in this sample. Effects of later age at first delivery in terms of mortality risk were stronger after 55 years and, especially, after 70 years. CONCLUSIONS: The findings offer support for Geronimus's weathering hypothesis. Predictors of longevity among African Americans may be distinct from predictors for the population as a whole.     

Effect of television viewing on food and nutrient intake among adolescents

ObjectiveAmong the behaviors associated with food intake, exposure to television is particularly important given the number of adolescents exposed. Also, increased time spent watching television has been associated with physical inactivity and with less desirable dietary intake among adolescents. The aim of this study was to examine the association between television viewing and dietary intake among 13-y-old adolescents.MethodsA cross-sectional evaluation was carried out in the 2003–2004 school year, including adolescents born in 1990 and enrolled in the schools of Porto, Portugal. Time spent watching TV was collected by self-administered questionnaires and dietary intake was evaluated using a food frequency questionnaire. Included in the analysis were 1436 adolescents.ResultsSpending more than 120 min per day watching TV was significantly associated with higher intake of total fat and polyunsaturated fat and with lower intake of magnesium, in both sexes. Additionally, in girls, spending more than 120 min per day watching TV was associated with lower intake of complex carbohydrates, fiber, total vitamin A, folate, vitamin C, calcium, iron, phosphorus, and potassium. In boys, higher intake of saturated fat and cholesterol was found among those spending more time watching TV.ConclusionsWe found that television viewing is associated with higher consumption of foods containing more fats and sugars and a lower consumption of fruits and vegetables. Consequently, adolescents who watched more television had a higher intake of total fat and polyunsaturated fat and a lower intake of minerals and vitamins. This dietary behavior among adolescents may have long-term health implications, not only limited to obesity.     

Stages of change and weight loss among rural African American women

OBJECTIVE: Obesity is a prevalent public health problem in the United States, especially for rural African American women, and causes increased morbidity and mortality. The purpose of this analysis was to determine whether the transtheoretical stages of change model was generalizable to weight loss intention among overweight and obese rural African American women and to identify important predictors of the stages of change. RESEARCH METHODS AND PROCEDURES: The study was conducted in two rural counties in central Virginia. A population-based sample of 200 women under the age of 40 completed questionnaires concerning weight loss behavior and beliefs about weight. Ordinal logistic regression was used to predict stage of change. RESULTS: A total of 142 of the 200 women (71%) were overweight or obese (body mass index of > or =25) and were classified into a stage of change. Overall, 30% of respondents were in the precontemplation stage, 15% in the contemplation stage, 48% in the preparation stage, 4% in the action stage, and 3% in the maintenance stage. Education, what friends think about weight, body mass index, and a scale of the positive aspects of weight loss were significant predictors of the stage of change (p < 0.05). CONCLUSIONS: Several predictors of stage were the same as those found in studies of other health behaviors, and this research provides support for applying a stages of change model for weight loss intention among rural African American women. Two predictors in particular, significance of what friends think about weight and a scale of the positive aspects of weight loss, have implications for health education initiatives and social support in weight loss interventions.     

Osteoporosis and African American women

The incidence of osteoporosis and related fractures in African American women is half that of Caucasian women. African American women who sustain osteoporosis-related fractures have increased disability and decreased survival. Given the exponential increase in hip fracture rate among African American women over the age of 70 years, the risk of osteoporosis among this population may be underestimated. This review focuses on racial differences in women's bone mineral density (BMD) and bone metabolism and on various explanations for these observed differences. Environmental risk factors for osteoporosis and related fractures among African American women and modalities for prevention and treatment of osteoporosis are discussed. African American women begin menopause with higher BMD and have lower rates of women's bone loss after menopause, which account for their decreased incidence of osteoporosis and related fractures. The risk factors for osteoporosis among African American women are similar to those found in Caucasian women. Lifestyle interventions, such as calcium and vitamin D supplementation, smoking cessation, and increased physical activity, should be encouraged to enhance peak bone mass and to decrease bone loss. These interventions and other treatment modalities, such as hormone replacement therapy, bisphosphonates, and selective estrogen receptor modulators, should be studied further in African American women.
