Association between Meal Frequency and Weight Status in Spanish Children: A Prospective Cohort Study.

Childhood obesity is a major international problem, and unhealthy eating habits remain widespread. Increasing the frequency of meals of nutritious food can help children to regulate their appetite and maintain a healthy weight. However, there is scarce prospective evidence on the relationship between the meal frequency and weight outcomes. Therefore, the objective of the present study was to determine the prospective association between the meal frequency, body mass index, and waist circumference in Spanish children. Additionally, we analyzed the impact of the meal frequency on the incidence of excessive weight and abdominal obesity. The study included 1400 children with a mean (SD) age of 10.1 (0.6) and an average follow-up of 15 months. Anthropometric measurements, including the body weight, height, and waist circumference, were measured by trained personnel, and children were asked about whether they usually had the following meals: breakfast, a mid-morning snack, lunch, an afternoon snack, and dinner. Multiple linear regression models revealed a significant (p < 0.05) inverse association between the meal frequency with a standardized BMI (zBMI) and the waist-to-height ratio (WHtR) after adjusting for sex, age, allocation to an intervention group, school, maternal education, physical activity, diet quality, and for the corresponding outcome variable at the baseline. Furthermore, the odds of developing abdominal obesity or excessive weight during the follow-up significantly decreased with an increase in the meal frequency after controlling for the same confounders. In conclusion, a higher meal frequency at the baseline was predictive for a lower zBMI, WHtR, and odds of the incidence of excessive weight and abdominal obesity.

Parents' Diet Quality and Physical Activity Are Associated with Lifestyle in Spanish Children and Adolescents: The PASOS Study.

BACKGROUND: Non-communicable chronic diseases are associated with a low-quality diet, low physical activity, and sedentary behavior. OBJECTIVE: To assess how parents' diet and physical activity habits were associated with their offsprings' lifestyles. STUDY DESIGN: A cross-sectional analysis of 8-16-year-old children and adolescents (n = 2539; 51.9% girls) was carried out within the frame of the first edition of the Physical Activity, Sedentarism, Lifestyles, and Obesity in Spanish Youth study (PASOS-2019). Data on adherence to the Mediterranean Diet (MedDiet), daily moderate-vigorous physical activity (MVPA), and screen time per day (television, computer, video games, and mobile phone) were collected from children and adolescents, and data on parents' diet quality and physical activity were compiled. Logistic regression models were used to assess the association between parents' lifestyles and those of children and adolescents. RESULTS: High diet quality of parents was associated with higher adherence to the MedDiet of children and adolescents, as well as high consumption of fruit, vegetables, fish, nuts, and legumes. The high physical activity level of parents was associated with the low consumption of fast foods, sweets, and candies in children and adolescents. Children with high levels of physical activity were those whose parents showed better diet quality and physical activity levels. CONCLUSIONS: Parents' high diet quality and physical activity were associated with healthy lifestyles, higher adherence to the MedDiet, and physical activity of their offspring, mainly in adolescents.

Prospective Association between Adherence to the Mediterranean Diet and Health-Related Quality of Life in Spanish Children.

Health-Related Quality of Life (HRQoL) is gaining attention in children and adolescents because it is an important outcome of their health status and well-being. Therefore, it is important to identify determinants for HRQoL. Currently, there is scarce and mainly cross-sectional evidence on the relationship between adherence to the Mediterranean diet and HRQoL in children and adolescents. Therefore, the objective of the present study was to assess the prospective association between adherence to the Mediterranean diet and HRQoL in Spanish children. The study was carried out in 1371 children aged 8 to 10 from different Catalan elementary schools with a medium follow-up of 15 months. The KidMed and KIDSCREEN-10 questionnaires were used to assess the relationship between diet and HRQoL, respectively. The KidMed score at baseline was positively associated with HRQoL (ß = 0.320; 95% CI 0.101−0.540) after adjusting for confounders. Additionally, the logistic regression analysis showed positive associations between baseline consumption of fruit, vegetables, pulses, and high adherence to the Mediterranean diet and HRQoL at follow-up (p < 0.05 for all) while the consumption of fast-food, pasta or rice, baked good or pastries, and sweets were negatively correlated (p < 0.05 for all) with HRQoL at follow-up. In conclusion, adherence of the Mediterranean diet was predictive for HRQoL in Spanish children, but further prospective studies are needed to confirm this result.
