RESUMEN
BACKGROUND: To explore the vitamin D status with its demographic and lifestyle factors including dietary, supplementation, and physical activity in 0-5 years old children. METHODS: This was a large population-based cross-sectional multicentre study in which the children were recruited from 12 Children's Health Care Centers by a stratified cluster random-sampling method in 10 cities in Jiangsu Province, China. RESULTS: A total number of 5289 children were investigated. The prevalence of vitamin D deficiency was 30.1%. The concentration of 25 hydroxyvitamin D was 64.0 (46.3-83.0) nmol mL-1 after adjustment for covariates. Children with higher risk of vitamin D deficiency were more likely to be at older age, girls, survey conducted in spring, location in southern Jiangsu province, residence in urban, outdoor activity < 2 h day-1 (all p < 0.05). Moreover, those with lower risk were more likely to be the number of parity ≥ 2 times, vitamin D supplementation from birth to 6 months, the initial time of vitamin D supplementation after birth ≤ 1 months, vitamin D and calcium supplementation in the last 3 months, and dose of vitamin D supplementation > 400 IU day-1 (all p < 0.05). Children with preferences for sweets, meat consumption > 150.0 g day-1 , milk consumption < 250 mL day-1 , time of sleeping < 10 h day-1 had higher risks of vitamin D deficiency. However, these relationships were affected by demographics. CONCLUSIONS: Vitamin D status during the first five years of life was suboptimal and was associated with demographic and lifestyle determinants including milk, meat, sweets, vitamin D and calcium supplementation, sleeping and outdoor activity.

A new species of Scorpiops Peters, 1861 is described from Wuxi and Wushan County, Chongqing City, China. The new species is mainly characterized by a moderate size, in relation to the other species of genus, with dark reddish-brown to reddish-black coloration; 15-17 (usually 17) external trichobothria (5 eb, 1-2 esb, 1-2 em, 4 est, 4 et), 8-11 (usually 10) ventral trichobothria in the pedipalp patella and 4-5 (usually 5) ventral trichobothria on chela; pedipalp chela fingers are scalloped in males and nearly straight in females. With the present description the number of known species of Scorpiops recorded from China is raised to 33.

Evidence on the association of 25-hydroxyvitamin D (25[OH]D) and obesity during the first 5 years of life is limited in China. The objective of this study was to examine the associations between weight, weight for age z score (ZWAZ), weight for length/height z score (ZWHZ), and body mass index for age z score (ZBMI) and 25(OH)D. This was a large population-based cross-sectional multicenter study in which the children aged 0-5 years were recruited from 12 children's healthcare centers by a stratified cluster random-sampling method in 10 cities of the Jiangsu province, China. The 25(OH)D concentration was determined by ELISA. A total of 5289 children were investigated. For 0-71 months children with obesity and nonobesity, the prevalence of vitamin D deficiency was 36.0% and 29.8%, and the 25(OH)D level was 59.8 and 64.0 nmol/L, respectively, and there were all significant difference. Compared with children with nonobesity, children with obesity had higher risk of vitamin D deficiency (OR [95% CI]: 1.33 [1.02, 1.72], p < .05), and had lower 25(OH)D level (ß = -3.84, 95% CI = -7.58, -0.09, p < .05). The results for children aged 24-71 months were similar to those for children aged 0-71 months. However, no significant difference was observed in children aged 0-23 months. Vitamin D deficiency was observed in children with greater adiposity during the first 5 years of life. However, the results mainly came from those in the age group of 2 to 5 years instead of the first 2 years in their lives.
RESUMEN
Scorpiopslourencoi sp. nov. is described from Shigatse, Xizang. Scorpiopsatomatus Qi, Zhu & Lourenço, 2005 and Scorpiopspococki Qi, Zhu & Lourenço, 2005 were synonymized by Kovarík et al. (2020) as two junior synonyms of Scorpiopstibetanus Hirst, 1911 but based on several field surveys in Xizang in recent years, and a careful survey of the literature, S.atomatus is reaffirmed as a valid species and S.tibetanus is redescribed, both based on newly collected specimens. This brings the total number of species of Scorpiops recorded in China to 32.
RESUMEN
OBJECTIVE: Data on obesity in relation to bone mineral density(BMD) in infants and preschool children were sparse in China. The objective of this study was to examine the associations between body mass index (BMI) and BMD. SUBJECTS AND METHODS: This was a large population-based multicenter study in which the representative children aged 0-5 years were recruited from 13 Children's Health Care Centers by a stratified cluster random-sampling method in Jiangsu Province, China. BMD was measured by using quantitative ultrasound. The association of BMD with BMI and obesity were evaluated using multiple linear regression and logistic regression analysis taking into account the effects of confounders. The relations between age, weight, height, BMI and BMD were analyzed by using Pearson's correlation and further tested using partial correlation in the additive model. RESULTS: A total of 5,289 children (2786 boys and 2503 girls) were recruited. The BMD was positively linear relation with age, length/height, and was inversely linear relation with BMI (r=0.711, P<0.001; r=0.727, P<0.001; r=-0.318, P<0.001, respectively). The BMD gradually increased when the weight was in the range within 21.2kg, but started to gain slowlyand even decreased when the weight was over 21.2kg. After adjusting for confounders, compared with control group, children with obesityhad higher odds of low BMD (OR 95%CI: 2.73 (1.57, 4.76), P<0.001), the speed of sound (SOS)value in children with obesity was lower 47.45 (ß=-47.45, 95%CI=-85.07, -9.83, P=0.013). CONCLUSIONS: Adiposity was not advantageous for bone mineral density in 0-5-year-old Chinese children.
