“…Better than previous investigations which were of small sample sizes and did not display detailed age-specific information about nutritional status, in this study, we found that the overall prevalence of overweight and obesity were 11.6% and 11.2% among children and adolescents in Zhejiang Province, higher than that of in Shandong Province and Jiangsu Province [13,14], and higher than our previous study on children and adolescent [15]. The prevalence of overweight and obesity was 26.3% among males, higher than 19.4% among females, and this difference between genders is consistent with results from previous studies throughout China [16][17][18].…”

Objective To explore the sociodemographic disparity in the nutritional status including BMI, vitamin D and vitamin A status among children and adolescents in Zhejiang Province. Methods Weight, height serum 25-hydroxyvitamin D, and serum retinol were assessed in 2818 children and adolescents (6-17 years of age), using ten investigation sites in Zhejiang Province including urban and rural areas data from the China National Nutritional Study 2016-2017, which is a nationally representative cross-sectional study, to form provincial representative sample of Zhejiang Province. Sociodemographic disparity was explored. Results The prevalence of low weight, eutrophic, overweight and obese were 6.7%, 70.4%, 11.6%, and 11.2%, respectively. Significant difference was observed on BMI between males and females (P < 0.05), and between urban and rural areas (P < 0.05). The prevalence of vitamin D deficiency, inadequacy, normal and appropriate were 1.8%, 34.9%, 46.4% and 16.9%, respectively. Significant difference was observed on the concentration of 25-hydroxyvitamin D (25(OH)D) both between genders and between living areas (P < 0.05). The prevalence of vitamin A deficiency, marginal deficiency and appropriate were 4.5%, 24.7%, and 70.9%, respectively. Significant difference was observed on the concentration of retinol between living area (P < 0.05). Conclusions Overweight and obesity, deficiency and inadequacy of vitamin D, deficiency and marginal deficiency of vitamin A were prevalent among children and adolescents. There were disparities between genders and between living areas on the nutritional status. Regional and sex-specific guidelines and public health policies for children and adolescent nutrition are needed.

“…The results of prevalence were consistent with other researches in terms of gender, urban and rural areas (boys > girls, urban > rural) [13,37]. The difference between the sexes may be caused by the corporeity that boys are more prone to be obese than girls (e.g.…”

Background: Overweight and obesity are becoming a big issue in Shandong province. Based on the big data of children and adolescents in Shandong province, we try to explore the spatial differences and explain the causes of this phenomenon, so as to provide suggestions and data support for solving related problems in similar areas. Methods: The sample came from Shandong province's physical examination data in 2017. A total of 10.27 million schoolchildren aged 6-18 years were included. ArcGIS software (hot spot analysis) was used to explore the spatial differences, and regional influencing factors were analyzed by multinomial logistic regression.Results: The prevalence of overweight and obesity among schoolchildren aged 6-18 years were 17.93% and 6.79%, respectively. Moreover, boys/girls, urban/rural areas both showed that the former rate was higher than the latter, and the 9-11 age group was confirmed to have the highest prevalence. Regional distribution illustrated that, in Shandong province, the areas with high prevalence of overweight and obesity were mainly concentrated in the central, northern and eastern parts, and the hot spot clusters were located in Yantai and Weihai, while the low-value areas were aggregated in the western (boys) and southern (girls) regions. Further exploration revealed that total retail sales of consumer goods (CGTRS) and per capita disposable income (PCDI) were confirmed as risk factors for regional obesity level.Conclusions: The spatial difference of overweight and obesity is statistically significant between the eastern region (high value cluster) and the western region (low value cluster), and it is influenced by some regional factors, suggesting that for a few regions, relevant department should pay more attention to this phenomenon. More education on this problem should be done to make people know more about health, and more researches should be done to see what intervention could solve this problem.

“…Previous studies have shown that there was a certain association between VI and overweight and obesity [35]-mainly influenced by sports activities [12,31]. Likewise, previous research on obesity in the same population found that the high prevalence area was exactly consistent with the above results [36]. Initial speculation suggests that children in If subdivided by gender, the distribution characteristics (including total, mild and moderate to severe VI) were highly consistent with the overall, and the results for boys and girls were similar.…”

Background Visual impairment is a common child health problem. We hopes to analyze the regional trend, related factors and spatial distribution of children's visual impairment in Shandong province, to explore the spatial changes brought by time and their influencing factors, so as to provide scientific basis for prevention of childhood visual impairment. Methods This study covers 5 complete cross-sectional surveys (Physical examination data in Shandong province) from 2013 to 2017, involving about 29.24 million students. The 11th International Classification of Diseases was selected as the diagnostic standard. Spatial autocorrelation and hotspot analysis methods in ArcGIS software were used to analyze spatial features. The associated factors were analyzed by multinomial logistic regression. Results The visual impairment prevalence showed a trend of decreasing first and then increasing from 2013–2017, with slight changes. In terms of regional spatial differences, Weihai and Yantai have the highest VI rates in all years, and there was a large-scale spatial aggregation phenomenon. The southern low-value clusters, however, showed a weakening year by year. Further exploration revealed that the per capita disposable income of rural households, the growth rate of gross domestic product, total retail sales of consumer goods and number of full-time teachers were verified as risk factors for regional visual impairment levels. Conclusions The slight rebound of the prevalence of visual impairment and the high rate in the eastern and northern regions of Shandong province need more attention. It is suggested that relevant departments should focus on the influence of regional economic and educational factors when formulating relevant strategies.
