Obesity among male adolescent migrants in Vienna, Austria

Childhood overweight and obesity - especially among migrant children - are health problems in several European countries. The prevalence rates of overweight and obesity among 936 migrant boys of low socio-economic status from Turkey and former Yugoslavia were compared with those of Austrian boys in Vienna. In the longitudinal study, children were measured at the ages of 6, 10 and 15 years. Weight status was estimated by means of the body mass index and percentile curves were used for weight status classification. The prevalence of overweight and obesity was high among migrant boys as well as Austrian boys at all age groups. Ten-year-old boys from Yugoslavia exhibited the highest percentage of overweight (nearly 38%). The lowest percentage of overweight was among 6-year-old Austrian boys (17.2%). Being overweight or obese at the age of 6 years increased the risk of being overweight at 10 and 15 years significantly (p < 0.001). This was true of all groups independent of migrant status. The impact of migrant status on weight status at the ages of 10 and 15 was not significant. Therefore, although migrant boys from former Yugoslavia exhibited the highest rates of overweight and obesity, migrant status is not associated significantly with an increased prevalence of obesity in this sample characterized by a generally low socio-economic status. Prevention should start as early as possible for all children, since overweight tends to persist from childhood into adolescence independent of migrant status.
