The purpose of this study was to examine the differences among actual body size, perceived body size and ideal body size in overweight and obese young adult women

Promoting Healthy Growth or Feeding Obesity? The Need for Evidence-Based Oversight of Infant Nutritional Supplement Claims

The Developmental Origins of Health and Disease (DOHaD) model recognizes growth in infancy and childhood as a fundamental determinant of lifespan health. Evidence of long-term health risks among small neonates who subsequently grow rapidly poses a challenge for interventions aiming to support healthy growth, not merely drive weight gain. Defining healthy growth beyond “getting bigger” is essential as infant and young child feeding industries expand. Liquid-based nutritional supplements, originally formulated for undernourished children, are increasingly marketed for and consumed by children generally. Clarifying the nature of the evidentiary base on which structure/function claims promoting “healthy growth” are constructed is important to curb invalid generalizations. Evidence points to changing social beliefs and cultural practices surrounding supplementary feeding, raising specific concerns about the long-term health consequences of an associated altered feeding culture, including reduced dietary variety and weight gain. Reassessing the evidence for and relevance of dietary supplements’ “promoting healthy growth” claims for otherwise healthy children is both needed in a time of global obesity and an opportunity to refine intervention approaches among small children for whom rapid subsequent growth in early life augments risk for chronic disease. Scientific and health care partnerships are needed to consider current governmental oversight shortfalls in protecting vulnerable populations from overconsumption. This is important because we may be doing more harm than good

Stature and robusticity during the agricultural transition: Evidence from the bioarchaeological record

The population explosion that followed the Neolithic revolution was initially explained by improved health experiences for agriculturalists. However, empirical studies of societies shifting subsistence from foraging to primary food production have found evidence for deteriorating health from an increase in infectious and dental disease and a rise in nutritional deficiencies. In Paleopathology at the Origins of Agriculture (Cohen and Armelagos, 1984), this trend towards declining health was observed for 19 of 21 societies undergoing the agricultural transformation. The counterintuitive increase in nutritional diseases resulted from seasonal hunger, reliance on single crops deficient in essential nutrients, crop blights, social inequalities, and trade. In this study, we examined the evidence of stature reduction in studies since 1984 to evaluate if the trend towards decreased health after agricultural transitions remains. The trend towards a decrease in adult height and a general reduction of overall health during times of subsistence change remains valid, with the majority of studies finding stature to decline as the reliance on agriculture increased. The impact of agriculture, accompanied by increasing population density and a rise in infectious disease, was observed to decrease stature in populations from across the entire globe and regardless of the temporal period during which agriculture was adopted, including Europe, Africa, the Middle East, Asia, South America, and North America.Stature Skeletal robusticity Agricultural transition Paleopathology

Fetal programming and eating disorder risk

•The fetal environment impacts anorexia and bulimia development later in life.•Maternal malnutrition and stress are key factors influencing the fetal environment.•Maternal and fetal birth stressors and complications are associated with eating disorder risk.•Translation of research results focuses on preventative measures of maternal stressors. Fetal programming describes the process by which environmental stimuli impact fetal development to influence disease development later in life. Our analysis summarizes evidence for the role of fetal programming in eating disorder etiology through review of studies demonstrating specific obstetric complications and later eating risk of anorexia or bulimia. Using Pubmed, we found thirteen studies investigating obstetric factors and eating disorder risk published between 1999 and 2016. We then discuss modifiable maternal risk factors, including nutrition and stress, that influence anorexia or bulimia risk of their offspring. Translation of these findings applies to preventative strategies by health organizations and physicians to provide optimal health for mothers and their children to prevent development of medical and psychiatric illnesses
