Unformatted text preview: Module 3 --- Article 6 TREATMENT HIGHLIGHTS COURSE OF OVERWEIGHT/OBESITY IN CHILDHOOD Children who are overweight or obese during part or all of the preschool or elementary school period are found to be at increased risk for being overweight or obese at age 12. This study was designed to “assist clinicians by estimating the predictive value of earlier levels of BMI [body mass index1] status on later risk of overweight and obesity during the middle childhood and early adolescent years.” In a longitudinal study, growth data were collected on 1042 healthy children from 10 different locations. Height and weight of participants were measured at the following 7 time points: 2, 3, and 4½ years of age (preschool period), and 7, 9, 11, and 12 years of age (elementary school period). Children were classified as overweight if their BMI was at the 85th percentile or above. The criterion for obesity was BMI at the 95th percentile or above. Data on all 7 time points were available for only 555 participants, and only these data were used when analyses called for determining the risk of being overweight/obese at age 12 based on the frequency of having had certain BMIs. Children who were overweight/obese (ie, BMI at the 85th percentile or above) at least once during the preschool period were more than 5 times as likely to be overweight/obese at age 12 than those who were never overweight/ obese during that time period. Also, the more often the child had been overweight/obese during the elementary school period, the greater the likelihood of being overweight/obese at age 12 (“1 time = 25 times more likely, 2 times = 159 times more likely, 3 times = 374 times more likely”). Being overweight/obese at any point during the preschool period was associated with a 60% likelihood of being overweight/obese at age 12. Being overweight/obese at any point during the elementary school period was associated with an 80% likelihood of being overweight/obese at age 12. It was also found that among children who were not overweight/obese during the preschool or elementary school years, but whose BMIs were between the 75th and 84th percentiles at any time during those years, there was an increased likelihood of being overweight at age 12. The authors conclude that “these findings suggest that parents and health care providers may want to be even more vigilant than currently recommended in recognizing early signs of being on the path to overweight,” and that parent counseling to address the eating and activity patterns of the at-risk child should not be delayed “in hopes that overweight and the patterns that support it will resolve themselves in due course.”
