AbstractObesity and underweight trends in Hong Kong primary school children Ho SY1, Ruan RL1, Fong DYT2, Lee KY3, Chung WH3, Lam TH1 1 School of Public Health, The University of Hong Kong 2 School of Nursing, The University of Hong Kong 3 The Student Health Service, The Department of Health, Government of Hong Kong SAR The Student Health Service in Hong Kong measures the weight status of primary school students annually . We analysed these cross-sectional datasets on obesity and underweight trends from 1995/96 to 2008/09. An average of 334325 students per school year were analysed. Obesity and underweight were defined using body mass index cutoffs of 25 and 18.5 kg/m2, respectively, at age 18. Overall, sex, age and parental education specific prevalence estimates were calculated after weighting by sex and/or age. Obesity increased from 1995/96 to 2008/09 (16.1%-23.3%, 44.7% increase) overall, and greater increases were observed in boys (19.0% to 28.2%, 48.4% increase) than girls (13.0% to 18.0%, 38.5% increase), in younger age groups (<8 years 55.4%; 8-9 years 43.5%; ≥10 years 41.5%), and those with less educated parents (primary education or below 59.1%; secondary 53.1%; tertiary 30.4%). Underweight decreased from 17.6% to 11.4% (35.2% decrease) overall, and greater decreases were observed in boys (15.3% to 9.6%, 37.3% decrease) than girls (20.1% to 13.4%, 33.3% decrease), in the youngest age group (<8 years 36.8%; 8-9 years 33.9%; ≥10 years 35.5%), and those with less educated parents (primary education or below 37.1%; secondary 33.9%; tertiary 26.9%). In sum, the prevalence of obesity increased and underweight decreased in Hong Kong primary school children from 1995/96 to 2008/09. Greater increases in obesity were observed in boys, younger age groups and those with less educated parents.
