Total diet study approach was used to assess the dietary intakes of pesticide residues among the select population in Hyderabad. When assessed by a food frequency questionnaire, it was found that the food intakes varied among five socioeconomic sections (SES). Therefore, we intended to compare the intakes of pesticide residues through these foods among the five SES. A total of 195 foods from different markets were collected and analyzed for 19 pesticides. The residues were analyzed with a gas chromatograph and were confirmed with mass spectrometry. About 51 % of the samples were detected with one or more residues. Thirteen out of the 19 residues were present in levels above detection limits in various concentrations. The median concentrations of the residues in all the samples tested, ranged from 0.00010 to 0.33 mg/kg. Highest median concentration was for β-HCH in water samples. Exposures to all the residues were below the respective ADIs at both mean and 95th percentile levels of food intakes with highest estimated dietary intakes (EDIs) of β-HCH in both the cases. The EDIs of β-HCH were the highest among all the residues at both the intake levels among all the SES. The EDIs of β-HCH were significantly higher in lower SES than higher SES possibly due to the consumption of rice cooked in water contaminated with β-HCH. EDIs for other residues did not differ significantly among the five SES. [ABSTRACT FROM AUTHOR]

Anxiety disorders are highly prevalent and have negative consequences on individual and societal level. This study examined the usefulness of screening for anxiety disorders in primary school children. More specifically, the value of the screening method to discriminate between and to predict anxiety disorders was studied. Children and their parents were selected if the children had self-reported scores on the screening questionnaire Screen for Child Anxiety Related Emotional Disorders-71 (SCARED-71) within the top-15% (High-anxious) or from two points below to two points above the median (Median-anxious). Of the selected children, 183 high-anxious children and their parents, and 80 median-anxious children and their parents took part in a diagnostic interview, the Anxiety Disorder Interview Schedule (ADIS). Of the high-anxious children, 60% had an anxiety disorder versus 23% of the median-anxious children, whereas groups did not differ on rates of dysthymia/depression and attention deficit hyperactivity disorder. The diagnoses separation anxiety disorder, social phobia and specific phobia were specifically predicted by the corresponding subscales of the screening questionnaire, while the diagnosis generalised anxiety disorder was not predicted by any of the subscales. The screening method has proven its utility for discriminating between children with and without anxiety disorders when applying the top-15% cut-off. Moreover, separation anxiety disorder, social phobia, and specific phobia, all known to be prevalent and debilitating childhood anxiety disorders, can be predicted by the corresponding subscale of the screening instrument.
