Dietary habits, metabolic health and vitamin D status in Greenlandic children.

ABSTRACT:

Objective

To compare the dietary habits of children living in northern villages and in the capital of Greenland, given the reported transition from traditional to westernised diet in adults over recent decades, and to explore the association between consumption of marine mammals and fish (MMF) and the children's metabolic profile and vitamin D status.

Design

Children answered an FFQ encompassing sixty-four individual food types pooled into six food categories. Their pubertal stage, body fat, fitness level, metabolic profile (non-HDL-cholesterol, glycated Hb, insulin, glucose, high-sensitivity C-reactive protein) as well as serum 25-hydroxyvitamin D (25(OH)D) concentration were evaluated.

Setting

Siorapaluk and Qaanaaq (north of Greenland) and Nuuk (west).

Participants

Children aged 6-18 years (n 177).

Results

MMF were most frequently eaten by children from Siorapaluk (mean (sd): 73·4 (14·1) times/month), followed by children from Qaanaaq (37·0 (25·0) times/month), and least often eaten by children from Nuuk (23·7 (24·6) times/month; P < 0·001). Children from Qaanaaq consumed 'junk food' more frequently (P < 0·001) and fruits and vegetables less frequently (P < 0·01) than children from Nuuk. MMF consumption was positively associated with serum 25(OH)D concentration (P < 0·05), but the overall prevalence of vitamin D deficiency was high (18 %). No association was found between MMF consumption and metabolic parameters.

Conclusions

The dietary transition and influence of western diets have spread to the north of Greenland and only the most remote place consumed a traditional diet highly based on MMF. We found no strong associations of MMF consumption with metabolic health, but a positive association with vitamin D status.

Project description:Objective: Vitamin D deficiency and insufficiency in children are global public health problems. However, few studies have focused on vitamin D status in healthy preschool children, especially in Asia. This study aimed to investigate vitamin D status and host-related factors in healthy preschool children in Hangzhou to analyze the impact of low vitamin D levels (<30 ng/mL) on health outcomes (obesity, early childhood caries, and respiratory tract infections). Methods: A total of 1,510 healthy children aged 24-72 months from 15 kindergartens in Hangzhou were included. Data on the children's gender, age, body mass index (BMI), caries, and blood samples available for vitamin D analysis were collected from June to August 2018. A total of 325 children aged 36-48 months took part in a survey on the frequency of respiratory tract infections in the last year. Results: The children's mean 25(OH)D level was 28.01 ± 7.29 ng/mL. A total of 11.4% of the children had vitamin D deficiency, and 52.6% had vitamin D insufficiency. Only 36.0% had vitamin D sufficiency. No significant difference was found by gender or BMI group. However, children in the obesity group had the highest prevalence of vitamin D deficiency and the lowest 25(OH)D levels. A significant negative correlation was found between the 25(OH)D level and child age (r = -0.144, p < 0.001). Regression analysis showed that the children's 25(OH)D levels decreased by 0.17 ng/mL per month with age. In addition, children with low vitamin D levels might increase the risk of obesity and early childhood caries. Multiple linear regression indicated that the number of caries in children increased by 0.08 per 1-ng/mL decrease in the 25(OH)D level (β = -0.08, p < 0.001). Conclusion: Vitamin D deficiency/insufficiency is a serious problem among healthy preschool children in Hangzhou. Public health policies or interventions should be implemented to ensure that preschool children have adequate vitamin D to reduce the risk of related diseases.

Project description:BACKGROUND:Lifestyles habits such as eating unhealthy foodscommence at home and are associated with the development of obesity and comorbidities such as insulin resistance, metabolic syndrome, and chronic degenerative diseases, which are the main causes of death in adults. The present study compared changes in dietary habits, behaviors and metabolic profiles of obese children whose mothers attended at the hospital to group sessions, with those who received the usual nutritional consultation. METHODS:Randomized clinical trial, 177 mother/obese child pairs participated, 90 in the intervention group and 87 in the control group. The intervention group attended six group education sessions to promote healthy eating, being this an alternative of change of habits in children with obesity. The control group received the usual nutritional consultation; both groups were followed up for 3 months. Frequency of food consumption, behaviors during feeding in the house and metabolic profile was evaluated. Mixed effect linear regression models were used to evaluate the effect of the intervention on the variables of interest, especially in HOMA-IR. RESULTS:The intervention group reduced the filling of their dishes (p = 0.009), forcing the children to finish meals (p = 0.003) and food substitution (p < 0.001), moreover increased the consumption of roasted foods (p = 0.046), fruits (p = 0.002) and vegetables (p < 0.001). The children in the control group slightly increased HOMA-IR levels (0.51; 95% CI - 0.48 to 1.50), while the children in the intervention group significantly decreased (- 1.22; 95% CI - 2.28 to - 1.16). The difference in HOMA-IR between the control and intervention group at the end of the follow-up was - 1.67; 95% CI: - 3.11 to - 0.24. CONCLUSIONS:The educational intervention improved some eating habits at home, as well as HOMA-IR levels; why we consider that it can be an extra resource in the management of childhood obesity.
