The duration between the onset of the symptoms and diagnosis was long, and the proportion of DKA in children with newly diagnosed diabetes mellitus was high. These findings call for a collaborative effort for the early recognition of symptoms by patients and physicians in order to avoid more severe types of presentation.

ObjectiveTo investigate the prevalence of anisometropia and associated parameters among school-aged children in Nantong, China.MethodsThis school-based, cross-sectional study examined students from primary schools, junior high schools, and senior high schools in an urban area of Nantong, China. Univariate and multivariate logistic regression analyses were used to investigate the specific correlations between anisometropia and related parameters. Non-cycloplegic autorefraction was assessed for each student. Anisometropia was defined as the spherical equivalent refraction (SE) difference ≥ 1.0 D between eyes.ResultsA total of 9,501 participants were validated for analyses, of which 53.2% (n = 5,054) were male, and 46.8% (n = 4,447) were female. The mean of age was 13.32 ± 3.49 years, ranging from 7–19 years. The overall prevalence of anisometropia was 25.6%. Factors such as myopia, scoliosis screening positive, hyperopia, female sex, older age, and higher weight had a significantly higher risk of anisometropia (p < 0.05).ConclusionThere was a high prevalence of anisometropia in school-age children. Some physical examination parameters are closely related to children’s anisometropia, especially myopia and scoliosis. Preventing myopia and controlling its progression may be the most important ways to reduce the prevalence of anisometropia. Correcting scoliosis may be an important factor in controlling the prevalence of anisometropia, and maintaining good reading and writing posture may be helpful in controlling the prevalence of anisometropia.
