Abstract

Although individuals with poor food security might be expected to have reduced food intake, and thus reduced body fat and less likelihood of being overweight, these associations have not been adequately studied. The purpose of the current study was to examine the relationship between food insecurity and overweight as measured by body mass index (BMI) using data from the nationally representative 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII). Overweight was defined as BMI >27.3 kg/m(2) for women and 27.8 kg/m(2) for men. Food insecurity was related to overweight status for women (n = 4509, P < 0.0001), but not for men (n = 4970, P = 0.44). Excluding the 11 severely insecure women, the prevalence of overweight among women increased as food insecurity increased, from 34% for those who were food secure (n = 3447), to 41% for those who were mildly food insecure (n = 966) and to 52% for those who were moderately food insecure (n = 86). Food insecurity remained a significant predictor of overweight status, after adjustment for potentially confounding demographic and lifestyle variables (P < 0.01). In a logistic regression analysis, mildly insecure women were 30% more likely to be overweight than those who were food secure [odds ratio (OR) 1.3, P = 0.005]. Thus, food insecurity had an unexpected and paradoxical association with overweight status among women with a higher prevalence of overweight among the food insecure, and a resulting potential for increased incidence of obesity-related chronic diseases. Given that the rates of both overweight and food insecurity are on the rise, this research area warrants further investigation. [ABSTRACT FROM AUTHOR]

15. UPTAKE OF COPPER IONS FROM SOLUTION BY DIFFERENT POPULATIONS OF MEDICAGO SATIVA (ALFALFA)

Author

Abstract

Seven different varieties of alfalfa plant tissues were tested for their ability to uptake copper ions from solution. Laboratory experiments were performed to determine the pH profiles, time dependency, capacity of copper uptake and desorption of the metal bound. Also, optimal biomass drying conditions (oven dried and lyophilized) as well as buffering effects on the copper uptake were examined. Differences in the roots and shoots were examined to determine the metal binding properties of seven alfalfa populations. Protein and crude fiber content was determined for all biomasses studied. Most of the biomasses studied showed a high affinity for copper ions as the pH increased from 2 to 6 with optimum copper binding around pH 5.0. Time dependency experiments for copper binding showed a very rapid adsorption of the copper ions by the various alfalfa species. Binding capacity experiments for copper binding showed that the capacities of the shoots are very similar, with African and Ladak germplasms being the highest. Binding capacities for the roots were similar with Malone populations being the highest. Overall, the shoots have higher binding capacity than the roots. As much as 98% of the copper bound to the various species was recovered by treatment with 0.1 M HC1. This innovative technology has great potential for the removal and recovery of heavy metal ions from contaminated waters.
