Body composition of mother-daughter family pairs in relation to dairy products and calcium intake.

摘要

We analysed the body composition of mother-daughter family pairs in relation to calcium and dairy products intake. The study covered 277 mother-daughter family pairs, aged 43.7+or-5.5 and 17.1+or-2.3 years, respectively. Dairy products (g/person/day) and usual calcium intake from dairy products and from daily diets (DD) were assessed with the food intake frequency method, using the validated ADOS-Ca questionnaire. Respondents' body composition was evaluated with anthropometric methods. The mother-daughter family pairs were divided into three subgroups (T1, T2, T3) according to tercile ranges of calcium intake from dairy products by mothers (T1: <245.7 mg/day; T2: 245.7/569.2 mg/day; T3 >569.2 mg/day). The T1 daughters consumed significantly less calcium from the DD than the T3 daughters (on average 820 and 1160 mg/day, respectively). The T1 mothers in comparison to the T3 mothers had significantly higher fat content in the body (on average by 3.7 kg), as well as waist (3.6 cm) and hips circumference (2.8 cm), they had more often the waist circumference >=88 cm (38.0% and 19.8% of the sample, respectively) and very high health loss risk resulting from big waist circumference and high BMI (27.2% and 10.4%, respectively). The T2 daughters in comparison to the T3 daughters had significantly greater suprailiac skinfold thickness (on average by 1.7 mm), hips circumference (3.1 cm) and fat content in the body (1.3%). Lower percentage of the T1 than T3 girls had the arm area >2SD (2.2% and 10.4%, respectively) and the arm muscle area >2SD (5.4% and 14.6%, respectively). Summarizing, a higher dairy products and calcium intake by mothers was favourable to a greater consumption of those products by daughters and, as a result, of a lower fat tissue content in women and to some extent in girls.
