CORREA-RODRIGUEZ, María; SCHMIDT-RIO VALLE, Jacqueline; DE LA FUENTE-VILCHEZ, Ángel Manuel  e  RUEDA-MEDINA, Blanca. Analysis of lifestyle and bone mineralization in a population of Spanish young adults. Colomb. Med. [online]. 2018, vol.49, n.3, pp.213-218. ISSN 1657-9534.  http://dx.doi.org/10.25100/cm.v49i2.2056.

Objective:

To analyze the environmental factors (nutritional status, levels of physical activity and nutritional habits) and their possible association with bone mass in a population of young adults.

Methods:

The study population consisted of 200 subjects (117 women and 83 men) aged between 18 and 25 years (mean age 20.4 years ±2.2 years). Body composition parameters were measured by an electronic balance (TANITA BC-418MA), nutritional habits were estimated by 72-h dietary recall, level of physical activity was assessed by the International Physical Activity Questionnaire (IPAQ) and bone mass was measured by ultrasonography at the calcaneus.

Results:

There were significant differences in bone mass values ​​according to gender (p= 0.013). Despite the fact that 70% of the subjects had a body mass index (BMI) within the normal range, 20% had overweight or obesity. 49% of the individuals had a moderate level of physical activity, although women had lower levels of physical activity than men (17.9% vs 8.4%). Most diets among young adults were hyperprotic, hyperlipidic and low-carbohydrates, with low-calcium and fiber intakes and high-phosphorus. Analysis of bone mass according to BMI showed higher values ​​as the weight category rises, with significant differences in women. Higher values ​​of bone mass were shown as the level of physical activity was higher, showing significant differences in males.

Conclusion:

Our results show that BMI and level of physical activity are significantly associated with bone health in a population of young adults, suggesting the relevance of promoting healthy lifestyles as a strategy for the early prevention of osteoporosis.
