Prenatal exposure to diethylstilbestrol (DES) is associated with adverse health outcomes, including anatomic anomalies of the reproductive tract in women and of the genitourinary tract in men. The mouse model, which replicates many DES-related effects seen in humans, suggests that prenatal DES exposure causes alterations that may affect the next generation of offspring. We asked women participating in a large, multi-centre study of prenatal DES exposure to report birth defects occurring among 4029 sons and 3808 daughters (i.e., the third generation). A subcohort of 793 third generation daughters was also queried for birth defects. We used logistic regression models to generate odds ratio and 95% confidence intervals for the association between prenatal DES exposure in the mother and birth defects in the offspring. Based on the mothers' reports, overall birth defects were elevated in the sons (OR = 1.53; 95% CI = 1.04, 2.23) and in the daughters (OR = 2.35; 95% CI = 1.44, 3.82). Most estimates of association were imprecise, but daughters appeared to have an excess of heart conditions (OR = 4.56; 95% CI = 1.27, 16.34). Our data suggest a possible association between the mother's prenatal DES exposure and birth defects in their offspring, particularly in daughters. We cannot, however, rule-out the possible influence of reporting bias. In particular, the exposed daughters' elevated risk of cardiac defects may be as a result of the underreporting of these conditions by unexposed mothers. © 2009 European Academy of Andrology.

OBJECTIVE: The objective of this study was to describe food and beverage brand placements in a large representative sample of popular movies. METHODS: We identified and coded brand placements for foods, beverages, and food retail establishments in the top 20 US box office movie hits for each year from 1996 to 2005. We also coded general movie characteristics (Motion Picture Association of America rating, run time, genre, and information about major characters). We summarized the number and types of food, beverage, and food retail establishment brands by movie characteristics and also identified manufacturers that are associated with each of the brands. RESULTS: Of the 200 movies coded, 138 (69%) contained at least 1 food, beverage, or food retail establishment brand. Movies rated PG-13 and R were significantly more likely to have brand placements compared with movies in other rating categories. Comedies, action/adventures, and horror films had more brand placements than other genres. We did not detect a significant difference in the number of movies with brand placements or mean number of placements per movie by year of movie release. A total of 1180 brand placements were identified and verified, including 427 food, 425 beverage, and 328 food retail establishment brand placements. Candy/confections (26%) and salty snacks (21%) were the most prevalent food brands, sugar-sweetened beverages (76%) were the most prevalent beverage brands, and fast food composed two thirds of the food retail establishment brand placements. CONCLUSIONS: Food, beverage, and food retail establishment brands are frequently portrayed in movies, and most of the brand placements are for energy-dense, nutrient-poor foods or product lines. Movies are a potent source of advertising to children, which has been largely overlooked. Copyright © 2010 by the American Academy of Pediatrics.

Diethylstilbestrol (DES) is a non-steroidal estrogen that was commonly prescribed during pregnancy from the late 1940s to 1971. A potent endocrine disruptor, prenatal DES exposure has been linked with reproductive tract malformations, adverse pregnancy outcomes, cancer, infertility and earlier menopause. DES was used for years as a growth promoter in animal production. Some animal studies suggest that prenatal DES exposure is associated with obesity and metabolic disturbances. Using data from the National Cancer Institute DES Follow-Up Study, we evaluated the association between DES and adult obesity, weight gain from age 20 to mid-life, central adiposity and height among 2871 prenatally exposed and 1352 unexposed women between 23 and 52 years of age (median 41.5) at baseline in 1994. DES exposure status was confirmed by prenatal medical record review. We used multivariable log-binomial models to calculate risk ratios (RRs) for obesity in 2006, and linear regression to calculate mean differences in body mass index, weight gain, waist circumference and height. The adjusted RR for DES and obesity was 1.09 [95% confidence interval (CI): 0.97, 1.22], and RRs were 1.23 (CI: 1.07, 1.42) and 1.05 (CI: 0.91, 1.20) for low and high estimated total DES dose, respectively, compared with no exposure. DES-exposed women gained slightly more weight than unexposed women [mean difference, 0.70 kg (CI: -0.27, 1.66)]. This study suggests that prenatal DES exposure may be associated with a small increase in adult obesity.

Diethylstilbestrol (DES), a synthetic estrogen widely prescribed to pregnant women in the mid-1900s, is a potent endocrine disruptor. Prenatal DES exposure has been associated with reproductive disorders in women, but little is known about its effects on endogenous hormones. We assessed the association between prenatal DES exposure and reproductive hormones among participants from the Harvard Study of Moods and Cycles (HSMC), a longitudinal study of premenopausal women aged 36-45 years from Massachusetts (1995-1999). Prenatal DES exposure was reported at baseline (43 DES exposed and 782 unexposed). Early follicular-phase concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol were measured at baseline and every 6 months during 36 months of follow-up. Inhibin B concentrations were measured through 18 months. We used multivariable logistic and repeated-measures linear regression to estimate odds ratios (OR) and percent differences in mean hormone values (β), respectively, comparing DES exposed with unexposed women, adjusted for potential confounders. DES-exposed women had lower mean concentrations of estradiol (pg/ml) (β=-15.6%, 95% confidence interval (CI): -26.5%, -3.2%) and inhibin B (pg/ml) (β=-20.3%, CI: -35.1%, -2.3%), and higher mean concentrations of FSH (IU/I) (β=12.2%, CI: -1.5%, 27.9%) and LH (IU/I) (β=10.4%, CI: -7.2%, 31.3%), than unexposed women. ORs for the association of DES with maximum FSH>10 IU/I and minimum inhibin B<45 pg/ml - indicators of low ovarian reserve - were 1.90 (CI: 0.86, 4.22) and 4.00 (CI: 0.88-18.1), respectively. Prenatal DES exposure was associated with variation in concentrations of FSH, estradiol and inhibin B among women of late reproductive age. © 2015 Cambridge University Press and the International Society for Developmental Origins of Health and Disease.

Purpose: Tobacco use using a waterpipe is an emerging trend among college students. Although cigarette smoking is low among college athletes, waterpipe tobacco smoking may appeal to this population. The purpose of this study was to compare cigarette and waterpipe tobacco smoking in terms of their associations with organized sport participation. Methods: In the spring of 2008, we conducted an online survey of 8,745 college students at eight institutions as part of the revised National College Health Assessment. We used multivariable regression models to assess the associations between tobacco use (cigarette and waterpipe) and organized sports participation. Results: Participants reported participation in varsity (5.2%), club (11.9%), and intramural (24.9%) athletics. Varsity athletes and individuals who were not varsity athletes had similar rates of waterpipe tobacco smoking (27.6% vs. 29.5%, p = .41). However, other types of athletes were more likely than their counterparts to have smoked waterpipe tobacco (35.1% vs. 28.7%, p < .001 for club sports and 34.8% vs. 27.7%, p < .001 for intramural sports). In fully-adjusted multivariable models, sports participants of any type had lower odds of having smoked cigarettes, whereas participants who played intramural sports (odds ratio = 1.15, 95% confidence interval = 1.03, 1.29) or club sports (odds ratio = 1.15, 95% confidence interval = 1.001, 1.33) had significantly higher odds of having smoked waterpipe tobacco. Conclusions: College athletes are susceptible to waterpipe tobacco use. In fact, compared with their nonathletic counterparts, club sports participants and intramural sports participants generally had higher odds of waterpipe tobacco smoking. Allure for waterpipe tobacco smoking may exist even for individuals who are traditionally considered at low risk for tobacco use. © 2010 Society for Adolescent Medicine.

BACKGROUND: Before 1971, several million women were exposed in utero to diethylstilbestrol (DES) given to their mothers to prevent pregnancy complications. Several adverse outcomes have been linked to such exposure, but their cumulative effects are not well understood. METHODS: We combined data from three studies initiated in the 1970s with continued longterm follow-up of 4653 women exposed in utero to DES and 1927 unexposed controls. We assessed the risks of 12 adverse outcomes linked to DES exposure, including cumulative risks to 45 years of age for reproductive outcomes and to 55 years of age for other outcomes, and their relationships to the baseline presence or absence of vaginal epithelial changes, which are correlated with a higher dose of, and earlier exposure to, DES in utero. RESULTS: Cumulative risks in women exposed to DES, as compared with those not exposed, were as follows: for infertility, 33.3% vs. 15.5% (hazard ratio, 2.37; 95% confidence interval [CI], 2.05 to 2.75); spontaneous abortion, 50.3% vs. 38.6% (hazard ratio, 1.64; 95% CI, 1.42 to 1.88); preterm delivery, 53.3% vs. 17.8% (hazard ratio, 4.68; 95% CI, 3.74 to 5.86); loss of second-trimester pregnancy, 16.4% vs. 1.7% (hazard ratio, 3.77; 95% CI, 2.56 to 5.54); ectopic pregnancy, 14.6% vs. 2.9% (hazard ratio, 3.72; 95% CI, 2.58 to 5.38); preeclampsia, 26.4% vs. 13.7% (hazard ratio 1.42; 95% CI, 1.07 to 1.89); stillbirth, 8.9% vs. 2.6% (hazard ratio, 2.45; 95% CI, 1.33 to 4.54); early menopause, 5.1% vs. 1.7% (hazard ratio, 2.35; 95% CI, 1.67 to 3.31); grade 2 or higher cervical intraepithelial neoplasia, 6.9% vs. 3.4% (hazard ratio, 2.28; 95% CI, 1.59 to 3.27); and breast cancer at 40 years of age or older, 3.9% vs. 2.2% (hazard ratio, 1.82; 95% CI, 1.04 to 3.18). For most outcomes, the risks among exposed women were higher for those with vaginal epithelial changes than for those without such changes. CONCLUSIONS: In utero exposure of women to DES is associated with a high lifetime risk of a broad spectrum of adverse health outcomes. (Funded by the National Cancer Institute.)

Objective: The purpose of this paper is to highlight disparities between injection drug users (IDUs) and those who had never been IDUs from the Nutrition for Healthy Living (NFHL) cohort. Although IDUs were enrolled in the cohort throughout its duration, few analyses have sought to highlight findings specific to them. Methods: NFHL, a prospective, longitudinal cohort conducted from 1995-2005, included 881 human immunodeficiency virus (HIV) -infected men and women over the age of 18. Subjects were seen every 6 months; body composition and dietary and laboratory data were collected. Individuals were classified as current IDUs, past IDUs, and never-IDUs. The classification of ever-IDU combined current and past users. Results: In NFHL, a higher proportion of ever-IDUs were women, African American, had a high school education or less, smoked, and were housing insecure and food insecure compared to never-IDUs. Ever-IDUs had lower total, soluble, and insoluble fiber and individual micronutrient intakes. A higher proportion of ever-IDUs had hepatitis C and HIV-related symptoms, used highly active antiretroviral therapy (HAART) less, and had a CD4 count <500 cells/mm3, than never-IDUs, at the study endpoint. Conclusions: The course of HIV infection in past and current IDUs appears to be unique and requires more investigation. Physiologic and sociodemographic characteristics of IDUs contribute to poor disease management and nutritional status. Classic manifestations of HIV persist in IDUs in the HAART era.

OBJECTIVE: To compare the associations between weight status and different forms of physical activity among adolescents. METHODS: We conducted telephone surveys with 1718 New Hampshire and Vermont high school students and their parents as part of a longitudinal study of adolescent health. We surveyed adolescents about their team sports participation, other extracurricular physical activity, active commuting, physical education, recreational activity for fun, screen time, diet quality, and demographics. Overweight/obesity (BMI for age ≥ 85th percentile) and obesity (BMI for age ≥ 95 percentile) were based on self-reported height and weight. RESULTS: Overall, 29.0% (n = 498) of the sample was overweight/obese and 13.0% (n = 223) were obese. After adjustments, sports team participation was inversely related to overweight/obesity (relative risk [RR] = 0.73 [95% confidence interval (CI): 0.61, 0.87] for >2 sports teams versus 0) and obesity (RR = 0.61 [95% CI: 0.45, 0.81] for >2 sports teams versus 0). Additionally, active commuting to school was inversely related to obesity (RR = 0.67 [95% CI: 0.45, 0.99] for >3.5 days per week versus 0). Attributable risk estimates suggest obesity prevalence would decrease by 26.1% (95% CI: 9.4%, 42.8%) if all adolescents played on 2 sports teams per year and by 22.1% (95% CI: 0.1%, 43.3%) if all adolescents walked/biked to school at least 4 days per week. CONCLUSIONS: Team sport participation had the strongest and most consistent inverse association with weight status. Active commuting to school may reduce the risk of obesity, but not necessarily overweight, and should be studied further. Obesity prevention programs should consider strategies to increase team sport participation among all students. Copyright © 2012 by the American Academy of Pediatrics.

Undernutrition is a major contributor to child mortality and total global disease burden. Ready-to-use therapeutic food (RUTF) is recommended by theWorld Health Organization for community-based management of uncomplicated forms of severe acute malnutrition. New research has evaluated the role of RUTF for the prevention of childhood undernutrition. While studies have found some benefit, similar results have been seen with supplemental food aid and controversy over the role for RUTF in prevention efforts continues. For the prevention of childhood malnutrition, the following questions remain critical: Who should receive a specific nutrition intervention? What composition and form should the intervention take? And, when should the intervention be delivered. © 2010 International Life Sciences Institute.

Background: To improve diet quality and overall population health, the need to develop nutritional rating systems that are comprehensive in scope and easy for the consumer to understand and use at the point-of-purchase has emerged. Objective: Our aim was to examine the effect of a comprehensive storewide supermarket point-of-purchase nutrition navigation intervention by using a shelf-label 3-tiered star icon on consumer food and beverage choices and their associated nutritional quality. Design: By using a natural experiment design, purchasing data from 2006 to 2008 were obtained from a Northeast supermarket chain with 168 stores located in northern New England and New York and examined at preimplementation and at 1- and 2-y follow-up periods. Results: The nutrition navigation system studied showed significant changes in food purchasing immediately after implementation, and these changes continued to be significant 1 and 2 y later. When the same 8-mo period (January-August) each year was compared, in 2006, 24.50% of items purchased earned a star rating; this proportion increased to 24.98% (P < 0.001) and 25.89% (P < 0.0001) at the 1- and 2-y follow-up periods, respectively. For a 4-wk period, 1 y after program implementation, consumers purchased significantly more ready-to-eat cereals with stars (eg, less added sugars and more dietary fiber) and fewer no-star, high-sugar, low-fiber cereals. Conclusion: Increasing rates of obesity and declining diet quality for Americans strongly support the need for effective supermarket point-of-purchase programs, such as the Guiding Stars nutrition navigation program, that provide clear, concise, and simplified nutrition information to guide consumer food and beverage choices. © 2010 American Society for Nutrition.
