Patterns and problems of sleep in school going children.

This study was conducted to assess the sleep habits and problems of 103 young school going healthy children (3-10 yr) during their visit to hospital for minor illnesses or routine health visits for immunization. The average duration of daily sleep (nocturnal and daytime nap) was 10.32 and the percentage of children who took regular daytime nap was 28.2%. Co- sleeping, a traditional cultural practice in India was found in 93% of the children. Sleep related problems were reported in 42.7% children that included nocturnal enuresis (18.4%), sleep talking (14.6%), bruxism (11.6%) nightmares (6.8%), night terrors (2.9%) snoring (5.8%) and sleepwalking (1.9%). On univariate analysis, sleep related problems were notably common if it was nuclear family (Fishers exact test; P = 0.01), mother was younger in age (Mann Whitney U test; P= .04) and less educated (Mann Whitney U test; P=.04). However, when these predictors were entered simultaneously into a logistic regression model, only nuclear family remained as significant predictor of sleep related disorders (odds ratio 2.41; CI; 1.04-5.57). We conclude that sleep problems are frequent among healthy school going children seen at general pediatric practice.

Maternal estimates of mental age in developmental assessment.

OBJECTIVE: To examine the accuracy and clinical utility of maternal estimates of mental age in young children referred for developmental assessment. METHODS: Mothers of 100 children aged 16 to 60 months referred for developmental evaluation to psychology services of Department of Pediatrics of a tertiary care teaching hospital were asked to estimate the mental age of their child. Maternal estimates were converted to intelligence quotient (IQ) and were compared to results from developmental tests of cognitive and adaptive behavior functioning which were administered to all children. RESULTS: Maternal estimate IQ was highly correlated with IQ calculated from Developmental Profile II (r=.83, p<.001) and social quotient (SQ) calculated from Vineland Social Maturity Scale (r=.81, p<.001). Maternal estimate IQ was 82% sensitive to cognitive delay and 81% specific in identifying children likely to have normal development. Twenty seven percent of the maternal estimates were within +/- 5 IQ points of actual IQ. Mothers were more likely to overestimate their child's functioning. Maternal IQ (Mean=62.1, S.D. =25.8) was significantly higher (t=2.93, p<.004) than the actual IQ (Mean=57.9, S.D.=21.9). Step-wise multiple regression analysis revealed that the child's IQ and SQ explained 10% of the variance (F=6.40, p<.001) in maternal accuracy. The lower the SQ and IQ of the child, more accurate the estimates. CONCLUSION: Maternal estimates of mental age provide an accurate measure of developmental functioning in young children and may be used as a screening technique to identify a subset of children who need more detailed evaluation.
