ObjectiveThis study examined concern about child weight in mothers of weight-discordant siblings and determined the accuracy of maternal self-report versus measured child height, weight, and corresponding body mass index (BMI; kg/m(2)) z-score.
Design and SampleDiscordant sibling design. Forty-seven mothers of 5- to 12-year-old, weight-discordant siblings.
MeasuresMothers self-reported their concern about child weight for each child separately and for a subset of children, self-reported their heights and weights. Siblings' height, weight, waist circumference, and adiposity were measured.
ResultsThe majority (83%) of mothers expressed concern about their overweight/obese child's weight and 20% of mothers expressed concern about their normal-weight child's weight (p<.001). Difference scores in maternal concern about child weight were positively associated with difference scores in sibling BMI z-score (r=0.42; p=.01) and percent body fat (r=0.56; p<.001). For overweight/obese children only, maternal-reported child heights and weights were significantly lower compared to the measured values (p<.03).
ConclusionsOne fifth of mothers of weight-discordant siblings were unconcerned about their overweight/obese child's weight and for overweight/obese children only, mothers tended to underreport children's height and weight. Mothers' concern for their overweight/obese child's weight was greater for sibling pairs who were more discordant in their weight.
