Egg breakfast enhances weight loss.

OBJECTIVE: To test the hypotheses that an egg breakfast, in contrast to a bagel breakfast matched for energy density and total energy, would enhance weight loss in overweight and obese participants while on a reduced-calorie weight loss diet. SUBJECTS: Men and women (n=152), age 25-60 years, body mass index (BMI) >or=25 and

Eating and body image concerns among obese and average-weight children.

Research compared obese and average-weight children with regard to concerns about being or becoming overweight, history of dieting, concerns about the effects of eating food, and perceived discrepancy between real and ideal body image. Participants included 526 obese and average-weight elementary-age school children to whom questionnaires were administered. Gender (male/female), obesity status (obese/average-weight), and grade level (lower elementary/upper elementary) were considered. Obese children were significantly more likely to engage in dieting behaviors, to express concern about their weight, to restrain their eating, and to exhibit more dissatisfaction with their body image than average-weight children. Girls were more likely to exhibit these behaviors than were boys. These findings suggest the importance of studying the emergence of disordered eating habits in childhood.

Fear of intimacy among dating couples.

Fear of intimacy among heterosexual dating couples was examined with the Fear-of-Intimacy Scale (FIS) and the Personal Assessment of Intimacy in Relationships (PAIR). Following a 6-month interval, couples were again contacted to determine whether they continued to date. Males reported higher FIS scores than females, and FIS scores were positively correlated within couples. Also, FIS scores of males and females were significantly correlated with indices of actual and desired intimacy; however, for females, correlations of FIS scores with desired intimacy were significantly lower than correlations with actual intimacy. Females who were no longer in the dating relationship at the 6-month follow-up had higher FIS scores than those who were continuing in their dating relationship. These findings increase our understanding of fear of intimacy, especially gender differences in dating couples.

Predictors of body image dissatisfaction in elementary-age school girls.

Concerns about weight, shape, body image, dieting, and eating are evident among elementary-age school girls [Int. J. Eating Disord. 10 (1991) 199; J. Adolesc. Health 12 (1991) 307; Pediatrics 84 (1989) 482; J. Clin. Psychol. 21 (1992) 41; Addict. Behav. (2000).]. Body image dissatisfaction, found to predict the formation of eating disturbances in longitudinal studies [Eating Disord.: J. Treat. Prev. 2 (1994) 114; Int. J. Eating Disord. 18 (1995) 221.], is likely a necessary precursor of eating disturbance development [J. Abnorm. Psychol. 102 (1993) 438.]. Turning back the etiological clock, this study examines the association between body image dissatisfaction and four potential areas of influence, including peer relationships, family characteristics, personality features, and body mass index, among girls in grades three, four, and five. Each conceptual area significantly contributed to the prediction of body image dissatisfaction. The combination of statistically significant variables, including teasing, peer modeling of weight and shape concerns, daughters' perceptions of parental influence to lose or control weight, appearance comparison, sensitivity, and body mass index, accounted for 50% of the variance in general body image dissatisfaction and 45% in weight and shape dissatisfaction. Implications for prevention, treatment, and future research are discussed.

Determinants of exercise among children. II. A longitudinal analysis.

BACKGROUND: Research has demonstrated that physical activity serves an important preventive function against the development of cardiovascular disease. The recognition that U.S. children are often sedentary, coupled with the observation that physical activity habits tend to persist into adulthood, has prompted the investigation of exercise determinants consistent with social learning theory. The purposes of the present study were to identify social learning variables relevant to children's exercise and to explore the longitudinal predictive value of the determinants. METHODS: Data were collected from 111 families (N = 54 girls, N = 57 boys) who were interviewed in both Phase 1 (fifth and sixth grades) and Phase 2 (eight and ninth grades) of this study. Data from mothers (N = 111) were collected during both phases; data from 80 fathers were collected at Phase 2 only. RESULTS: The results of simultaneous stepwise regression analyses indicated that child's enjoyment of physical activity was the only consistent predictor of physical activity during Phase 1. At Phase 2, child's exercise knowledge, mother's physical activity, and child's and mother's friend modeling/support emerged as predictors for girls. For boys, child's self-efficacy for physical activity, exercise knowledge, parental modeling, and interest in sports media were important. Longitudinally, mother's self-efficacy, barriers to exercise, enjoyment of physical activity, and child's self-efficacy for physical activity were important for girls. Only child's exercise knowledge predicted boys' physical activity. The addition of information from fathers nearly doubled the explanatory power of the predictors for both genders. CONCLUSIONS: Socialization in the family unit exerts a tremendous influence on health-related behaviors such as exercise. The relative importance of determinants seems to differ for girls and boys and the pattern of these determinants appears to change over time.

Attitudes toward bulimic behaviors in two generations: the role of knowledge, body mass, gender, and bulimic symptomatology.

The perceived commonality and acceptability of symptoms of bulimia, as well as associated variables including gender, generation, knowledge of bulimia, body mass index, and bulimic symptomatology, were assessed. These views were explored in a sample of college students (N = 155 male; N = 173 female) and their parents (N = 194 mothers; N = 163 fathers). Females perceived bulimic symptoms to be more common than males, and students perceived them to be more common than their parents. Students perceived bulimic symptoms to be more acceptable than their parents. Females had higher levels of bulimic symptomatology, particularly daughters. Stepwise simultaneous regression analyses revealed that one's own level of bulimic symptomatology was the primary predictor of one's attitudes toward the commonality and acceptability of bulimic symptoms. Bulimic symptomatology was primarily predicted from perceptions of the acceptability of bulimic symptoms and body mass index. Results suggest that college-age students may be at greater risk for the development of bulimia nervosa because of their greater tolerance of these symptoms; alternatively, people endorsing higher levels of bulimic symptomatology may adjust their attitudes, perceiving bulimic symptoms to be more tolerable, in order to alleviate the dissonance between their attitudes and behaviors.
