The US market for organic foods has grown from $ 3.5 billion in 1996 to $ 28.6 billion in 2010, according to the Organic Trade Association. Organic products are now sold in specialty stores and conventional supermarkets. Organic products contain numerous marketing claims and terms, only some of which are standardized and regulated.In terms of health advantages, organic diets have been convincingly demonstrated to expose consumers to fewer pesticides associated with human disease. Organic farming has been demonstrated to have less environmental impact than conventional approaches. However, current evidence does not support any meaningful nutritional benefits or deficits from eating organic compared with conventionally grown foods, and there are no well-powered human studies that directly demonstrate health benefits or disease protection as a result of consuming an organic diet. Studies also have not demonstrated any detrimental or disease-promoting effects from an organic diet. Although organic foods regularly command a significant price premium, well-designed farming studies demonstrate that costs can be competitive and yields comparable to those of conventional farming techniques. Pediatricians should incorporate this evidence when discussing the health and environmental impact of organic foods and organic farming while continuing to encourage all patients and their families to attain optimal nutrition and dietary variety consistent with the US Department of Agriculture’s MyPlate recommendations.This clinical report reviews the health and environmental issues related to organic food production and consumption. It defines the term “organic,” reviews organic food-labeling standards, describes organic and conventional farming practices, and explores the cost and environmental implications of organic production techniques. It examines the evidence available on nutritional quality and production contaminants in conventionally produced and organic foods. Finally, this report provides guidance for pediatricians to assist them in advising their patients regarding organic and conventionally produced food choices.

We assessed the overall diet quality and adequacy of diet consumption of each component of the diet of adolescents according to demographic, socioeconomic and body mass index (BMI) data. A cross-sectional population-based study analyzed a representative sample of 409 adolescents, aged 12-19 years, using the Healthy Eating Index (HEI). We estimated the prevalence of diets classified in the first quartile of the HEI and the average scores of each component of the HEI. Linear and Poisson multiple regressions were used in the analysis. The mean score of HEI was 59.7. We observed a lower prevalence of inadequate diets in the segment with heads of household presenting higher schooling. The lower socioeconomic status segments, measured by income and schooling, showed a lower consumption of vegetables, fruits, dairy products and a less diversified diet, and a higher intake of cereals and legumes. Overweight/obese adolescents consume more meat and eggs and less fruit compared to low weight/normal weight adolescents. Girls had a higher intake of total fat and lower sodium intake. The results identified diet components that deserve more attention in the strategies to promote healthy eating, and the more vulnerable segments among adolescents.

The purpose of this study was to determine how pregnant women in the Midwestern United States use the internet for health information during pregnancy including information related to physical activity and nutrition, and to determine the impact of the internet on women’s confidence in making decisions about physical activity participation and eating behaviors during pregnancy. This was a descriptive, exploratory study using a convenient, non-probabilistic sample. Women were recruited through handouts provided in person, fliers posted at venues, or local websites that cater to women who are pregnant or up to 1 year post-partum. Overall, 293 women (28.5 years ± 4.9) completed the survey online (Survey Monkey) or in-print. Data were analyzed using descriptive statistics, paired t tests, and analyses of covariance. Almost all women used the internet for health information during their pregnancy. Half of women used the internet for information related to physical activity during their pregnancy and some increased their physical activity as a result. Women reported an increase in their confidence for making decisions related to physical activity during pregnancy after using the internet for physical activity information. Women that reported increases in physical activity during pregnancy, had greater increases in confidence for making decisions from using the internet compared to women who decreased or did not change their physical activity. Findings related to nutrition were similar to physical activity. However, there were no significant differences in increases in confidence between those who did or did not change the foods they ate. This study provides health promotional professionals useful information to consider when designing future physical activity and/or nutrition interventions for pregnant women.

OBJECTIVE: Weight preoccupations have been frequently reported in normal-weight subjects. Subthreshold anorexia nervosa (s-AN, all DSM IV TR criteria except amenorrhea or underweight) is a form of eating disorder not otherwise specified that has received scarce scientific attention. Under a case-control design we compared the general characteristics, body composition, and psychopathological features of normal-weight patients with s-AN with those of BMI- and sex-matched controls. DESIGN: Participants in this pilot study included 9 normal-weight women who met the DSM IV TR criteria for s-AN and 18 BMI-matched normal-weight controls. The general characteristics of the study participants were collected by questionnaire. Body composition was measured by bioelectrical impedance. Behavioral and psychological measures included the standardized symptom checklist (SCL-90-R) and the eating disorder inventory (EDI-2). RESULTS: There were no differences in age, education, employment status, marital status, and history of previous slimming treatment in the two study groups. In addition, anthropometric measures and body composition of s-AN patients and BMI-matched normal weight controls were not significantly different. In the s-AN subgroup, we found a significant relationship between waist circumference and the SCL-90-R obsessivity-compulsivity scale (n=9, r=-0.69, p<0.05). After multiple regression analysis, the SCL-90-R obsessivity-compulsivity scale (beta = 0.61, t=2.7, p=0.017) was the only independent predictor of the presence s-AN in our study cohort. CONCLUSIONS: These pilot results suggest that psychopathological criteria (particularly related to the obsessivity-compulsivity dimension) may be more useful than anthropometric measures for screening of s-AN in normal-weight women.
