Relationship between physical activity, dietary intake and bone parameters in 10-12 years old Hungarian boys and girls

Abstract

Objectives: Physical activity (PA) and adequate macro-and micronutrient intake have favourable influence on the bone status. The aim of this study was to analyse the relationships among PA, anthropometric data, dietary intake and ultrasound bone characteristics in children.Methods: 10-12 years old Hungarian children (N = 123, 59 girls, 64 boys) provided physical activity, diet, anthropometric and bone data. PA was measured with accelerometer (Actigraph GT3X+). Diet was evaluated with three-day, 24-hour food recall. Calcaneal quantitative ultrasound (QUS) bone parameters were registered with Sonost3000 bone densitometer.Results: Nutrition and anthropometry did not differ by gender. The values of broadband ultrasound attenuation (BUA) were significantly higher in boys. Girls spent significantly more time being sedentary, boys had greater light, moderate, vigorous, and moderate to vigorous physical activity (MVPA) levels. The children accumulated more than twice the suggested amount of public health guidelines for MVPA. QUS parameters correlated significantly with vigorous physical activity in boys, and with age, height, weight, fat percentage, and body mass index (BMI) for both genders. There was no significant relationship between nutrition and QUS; however, inadequate vitamin K intake correlated with less favourable bone parameters. Multiple linear regression analysis confirmed the importance of vigorous PA -speed of sound (SOS): β = 0.358, p = 0.006; BUA: β = 0.340, p = 0.007; bone quality index (BQI): β = 0.377, p = 0.002; vitamin K intake -SOS: β = 0.256, p = 0.025; BUA: β = 0.235, p = 0.033; BQI: β = 0.295, p = 0.007; BMI − SOS: β = 0.207, p = 0.064; BUA: β = 0.455, p < 0.001; BQI: β = 0.284, p = 0.008; and age -SOS: β = 0.450, p < 0.001; BUA: β = 0.318, p = 0.004; BQI: β = 0.444, p < 0.001).Conclusions: Changes in the characteristics of ultrasound bone parameters among 10-12 years old children mainly depended on the amount of intense PA, adequate vitamin K intake and anthropometric variables related to age.

A comparison of the associations between bone health and three different intensities of accelerometer-derived habitual physical activity in children and adolescents: a systematic review

“…Only 9/30 studies [39,41,53,54,58,[61][62][63][64] had a 'yes' response to item 9, where participants were required to have ≥ 4 days with ≥ 10 h of accelerometer data. Despite satisfying this requirement, four of these studies [58,[61][62][63] were still deemed to be of poor quality as they had not controlled for important covariates (e.g. age, sex, ethnicity, maturational stage, skeletal/body size) in the analyses when investigating independent associations between bone outcomes and each activity intensity (MPA and/or MVPA and VPA).…”

Are Children Suffering From Congenital Pseudarthrosis of the Tibia Associated With Bone Quality Decreased?

“…Our results show that the incidence of osteopenia in CPT group is higher than that in the control group, and the SOS, STI, QUI, and BMDe of CPT children are lower than those of non-bone metabolic disease children. SOS is an index to evaluate the bone quality and strength, which is proportional to bone mass and can better predict the risk of fracture [22]. Therefore, our results suggesting that the bone mass of children with CPT may be lower than the controls, and could be more prone to fracture.…”

The Impact of Vitamin K2 (Menaquionones) in Children’s Health and Diseases: A Review of the Literature

“…Physical activity and adequate nutrient intake have favorable influence on the bone quality. Hungarian researchers demonstrated that changes in bone mineral status among 10–12-year-old children, assessed by ultrasound method, are correlated with the amount of intense physical activity as well as with optimal vitamin K intake [ 32 ].…”
