Measurement characteristics of diet-related psychosocial questionnaires among African-American parents and their 8- to 10-year-old daughters: results from the Girls' health Enrichment Multi-site Studies.

OBJECTIVE: This paper presents the reliability and validity of several diet-related psychosocial questionnaires. METHODS: At baseline and 12 weeks follow-up, parents/caregivers of one hundred fifty 8- to 10-year-old African-American completed questionnaires on food preparation habits for their daughter, perceived home barriers to healthy eating, and fruit, juice, vegetable (FJV), low-fat and high-fat food availability. Girls completed a sweetened beverage preferences questionnaire and two 24-h dietary recalls to assess intake. Principal components analyses were conducted for two newly designed measures. Internal consistency was calculated and construct validity was assessed between the psychosocial scales and obesity-related dietary variables. RESULTS: Low-fat and high-fat food preparation for daughters, and perceived home barriers to eating low-fat food and FJV subscales were derived from the new questionnaires. Internal consistency reliabilities were moderate (0.58) to substantial (0.80) across all new and existing scales. Test-retest reliabilities were moderate (0.44) to substantial (0.79). Girls' intake of fat as a percentage of energy was positively related to parental high-fat food preparation for daughters (P < 0.01) and negatively related to parental low-fat food preparation practices for daughters (P < 0.05). CONCLUSIONS: Measures of family influences on FJV, fat, and sweetened beverage consumption were internally consistent with moderate to substantial stability. Scales for low-fat and high-fat food preparation practices for daughters achieved construct validity with fat consumption in the hypothesized direction. Family food preparation habits appear to be important targets for future interventions.

Social desirability bias in self-reported dietary, physical activity and weight concerns measures in 8- to 10-year-old African-American girls: results from the Girls Health Enrichment Multisite Studies (GEMS).

BACKGROUND: Social desirability (SocD) may bias children's self-reported health behaviors and attitudes and confound relationships with health outcome measures. METHODS: Ninety-five, 8- to 10-year-old African-American girls completed dietary recalls, a physical activity checklist, psychosocial questionnaires related to diet, and physical activity; and 3 days of physical activity monitoring. Potential SocD construct bias was investigated by comparing designated criterion measures of physical activity, beverage intake, and body mass index (BMI) with respective self-reported measures related to activity, beverage preferences, and body image and weight concerns in cross-sectional regression models. Potential confounding by SocD of associations between self-reported behaviors with BMI was assessed using change-in-coefficient regression analyses. RESULTS: Controlling for age and BMI, overestimates of self-reported activity (P = 0.02), underestimates of sweetened beverage preferences (P = 0.02), and lower ratings of weight concerns and dieting behaviors (P's < 0.05) were related to SocD. Confounding by SocD of associations between self-reported physical activity and energy intake with BMI was found. CONCLUSIONS: In 8- to 10-year-old African-American girls, SocD was found to bias self-reports of diet and physical activity and confound associations between BMI and self-reported physical activity and energy intake. Methods to measure and control SocD bias are needed to reduce potential distortion of relationships between diet and physical activity and health outcomes.

Body image perceptions and dieting among African-American pre-adolescent girls and parents/caregivers.

This study describes body image and weight concern attitudes of pre-adolescent African-American (AA) girls and their parent/caregivers. Cross-sectional survey data were collected from 189 low-income 8- to 10-year-old AA girls and 179 parents/caregivers of AA girls from 2 urban areas, Memphis and Minneapolis/St. Paul. Results demonstrated that most AA girls were either happy with their weight, or did not think about it at all. However, 20% of girls would like to be larger than their current size, and 50% would like to be smaller. Girls in Minneapolis/St. Paul were more likely than Memphis girls to report weight dissatisfaction. One third of parents reported concerns that their daughters were too heavy. Seventy-two percent of parents reported that they were trying to lose weight. Discussions include possible regional differences in weight concern among AA girls, and implications for obesity prevention programs.

Self-reported differences in daily raw vegetable intake by ethnicity in a breast screening program.

PURPOSE: While the literature has no conclusive causal relationship between nutrition and breast cancer, diet is believed to play a role in the development of breast cancer. This investigation focuses on differences of dietary practice between Caucasians and African Americans in a cohort of women presenting for breast cancer screening. METHODS: Over a one-year period, 675 women presenting to the Breast Health Center at Tulane University Medical Center for an initial visit were given a self-reported health behavior questionnaire. Included in this survey were questions concerning the frequency of raw vegetable consumption and fat/oil intake. MAIN FINDINGS: The overall proportion of women who presented for breast cancer screening that reported daily raw vegetable consumption in the study group was 40%. There were statistically significant differences between proportions of Caucasian women's and African American women's consumption of daily raw vegetable (51% versus 29%, respectively; P < 0.0001). These differences were not seen in daily fat/oil intake. No differences were seen in socioeconomic measures. CONCLUSIONS: There is a substantial difference in the consumption of potentially protective foods among major ethnic groups. These dietary differences should be taken into account when investigating the ethnic differences in women with breast cancer, as well as the relationship between breast cancer and nutrition.

Socioeconomic Factors, not Ethnicity, Predict Breast Self-Examination.

The American Cancer Society has recommended monthly breast self-examinations (BSEs) to aid in the early detection of breast cancer. Compliance with BSE recommendations has been shown to be decreased in certain ethnic groups. This investigation evaluates relevant variables involved in BSE compliance in an urban breast cancer screening center. A survey over a 1-year period (June 1996-June 1997) was given to all patients on their initial visit to the Breast Health Center at Tulane University Medical Center. Demographic and socioeconomic factors associated with the compliance of BSE were explored. The overall rate of BSE was relatively high at 80%. There was no difference between ethnic groups in rates of BSE (Caucasians 21% versus African Americans 20%). Statistically significant variables associated with BSE noncompliance were high school education (did not complete high school 16% versus completed high school 33%; p < 0.0004), employment status (employed 16% versus unemployed 31%; p < 0.0004), and marital status (married 15% versus single/divorced 22%; p < 0.05). While the majority of women in our study practiced BSE and ethnicity did not predict BSE, several socioeconomic factors were predictive of BSE compliance. Efforts to increase community outreach to lower socioeconomic patients as well as efforts to ensure proficient BSE techniques by patients may help detect early breast cancer.

Effect of a short structured session on medical student breast cancer screening knowledge.

Formalized instruction in breast cancer screening during medical school may help improve early breast cancer detection and survival. Physicians-in-training must be proficient in skills relating to breast cancer screening. This study investigates the baseline breast cancer screening knowledge of medical students, the benefit of a structured lecture session, and its effect on improving medical students' knowledge of cancer screening. A self-administrated questionnaire relating to breast cancer screening was given to third-year medical students. A 60-minute structured lecture session was given to the medical students regarding breast cancer screening. A postintervention survey was administered immediately following the session. A total of 27 medical students were evaluated. There was a statistically significant improvement following the formalized teaching session (84% to 93%; p < 0.0016). While few students (15%) reported having previous instruction in cancer screening, most students (96%) felt that a formal session should be offered during medical school. While medical student knowledge of breast cancer screening may be adequate, formalized instruction in breast cancer health practices can improve medical student knowledge. Most students had limited previous instruction in breast cancer prevention and welcomed the opportunity for structured training in breast cancer prevention, education, and detection. Until a formal course becomes a fundamental aspect of medical education, a short structured session should be instituted.

Multivariate analysis of factors associated with smoking cessation in women.

BACKGROUND: Appropriate smoking cessation techniques, including counseling patients to stop smoking, could prevent multiple health-related problems. Identification of relevant factors in patients that smoke may be beneficial in targeting smoking cessation efforts. This investigation explores various factors associated with smoking cessation, specifically in women. METHODS: All women (n = 675) presenting to a breast health center over a one year period were surveyed regarding their tobacco use. Any association between smoking cessation and various factors was determined by multivariate analysis. RESULTS: Our population consisted of 47% African American women, 43% Caucasian women, and 10% women of other ethnicities. Sixty percent of all women never smoked. Of the women who had smoked, 57% quit. Except for alcohol use and exercise, no factor, including ethnicity, was associated with never smoking. Smoking cessation was associated with being married, being Caucasian, not using alcohol, and exercising. However, only Caucasian race and marriage were independently associated with smoking cessation. DISCUSSION: In our population, African American women had a lower proportion of smoking cessation than Caucasian women. In patients with similar access to care, specifically preventive care, there are ethnic and social differences in smoking cessation.
