BackgroundStress-related eating is associated with unhealthy eating and drinking habits and an increased risk of obesity among adults, but less is known about factors related to stress-driven eating behaviour among children and adolescents. We studied the prevalence of stress-related eating and its association with overweight, obesity, abdominal obesity, dietary and other health behaviours at the age of 16. Furthermore, we examined whether stress-related eating is predicted by early-life factors including birth size and maternal gestational health.MethodsThe study population comprised 3598 girls and 3347 boys from the Northern Finland Birth Cohort 1986 (NFBC1986). Followed up since their antenatal period, adolescents underwent a clinical examination, and their stress-related eating behaviour, dietary habits and other health behaviours were assessed using a postal questionnaire. We examined associations using cross-tabulations followed by latent class analysis and logistic regression to profile the adolescents and explain the risk of obesity with behavioural traits.ResultsStress-related eating behaviour was more common among girls (43%) than among boys (15%). Compared with non-stress-driven eaters, stress-driven eaters had a higher prevalence of overweight, obesity and abdominal obesity. We found no significant associations between stress-eating and early-life factors. Among girls, tobacco use, shorter sleep, infrequent family meals and frequent consumption of chocolate, sweets, light sodas and alcohol were more prevalent among stress-driven eaters. Among boys, the proportions of those with frequent consumption of sausages, chocolate, sweets, hamburgers and pizza were greater among stress-driven eaters. For both genders, the proportions of those bingeing and using heavy exercise and strict diet for weight control were higher among stress-eaters. Besides a ‘healthy lifestyle’ cluster, latent class analysis revealed two other patterns (‘adverse habits’, ‘unbalanced weight control’) that significantly explained the risk of overweight among boys and girls.ConclusionsStress-related eating is highly prevalent among 16-year-old girls and is associated with obesity as well as adverse dietary and other health behaviours among both genders, but intrauterine conditions are seemingly uninvolved. In terms of obesity prevention and future health, adolescents who use eating as a passive way of coping could benefit from learning healthier strategies for stress and weight management.
Parental overweight conveys a major risk for overweight in children for which both parents' long-term overweight (BMI ≥25 kg m(-2) before pregnancy and after 16-year follow-up) was the strongest single predictor. Preventing intergenerational transmission of obesity by helping parents to maintain a healthy weight is an essential target for public health.
Objective To assess the association between maternal gestational weight gain (GWG) during the first 20 weeks of gestation and overweight/obesity and abdominal obesity of offspring at the age of 16 years.Design A prospective cohort study.Setting The two northernmost provinces of Finland.Population Mothers and their adolescent offspring born from singleton pregnancies (3265 boys; 3372 girls) in the Northern Finland Birth Cohort 1986.Methods Maternal weight at 20 weeks of gestation was measured in municipal maternity clinics. Maternal GWG was based on the difference between the measured weight and self-reported prepregnancy weight, and was classified into quartiles. Offspring weight, height and waist circumference were measured by study nurses during a clinical examination. Logistic regression analyses [with and without adjustment for maternal pre-pregnancy body mass index (BMI), glucose metabolism, education level, haemoglobin, smoking status, parity, and gender of offspring] were performed.Main outcome measure Offspring overweight/obesity, based on BMI and abdominal obesity at 16 years.Results The highest quartile of maternal weight gain (>7.0 kg during the first 20 weeks of gestation) was independently associated with BMI-based overweight/obesity and abdominal obesity in the 16-year-old offspring (OR 1.46, 95% CI 1.16-1.83, and OR 1.37, 95% CI 1.10-1.72, respectively). Among all covariates, maternal pregravid obesity showed the highest odds for both overweight/obesity and abdominal obesity (OR 4.57, and OR 4.43, respectively).Conclusions Maternal overnutrition during the first half of gestation predicts offspring overweight/obesity and abdominal obesity in adolescence, yet a high pregravid BMI appears to be a more important determinant of both outcomes.
We utilized longitudinal data on both the work ability index (WAI) and the work ability score (WAS) to predict disability pension (DP) among men and women. We also took into account the effect of job content on the associations. Based on the results, WAS can be considered a good alternative to WAI in the prediction of DP.
Recent studies suggest that meal frequencies influence the risk of obesity in children and adolescents. It has also been shown that multiple genetic loci predispose to obesity already in youth. However, it is unknown whether meal frequencies could modulate the association between single nucleotide polymorphisms (SNPs) and the risk of obesity. We examined the effect of two meal patterns on weekdays –5 meals including breakfast (regular) and ≤4 meals with or without breakfast (meal skipping) – on the genetic susceptibility to increased body mass index (BMI) in Finnish adolescents. Eight variants representing 8 early-life obesity-susceptibility loci, including FTO and MC4R, were genotyped in 2215 boys and 2449 girls aged 16 years from the population-based Northern Finland Birth Cohort 1986. A genetic risk score (GRS) was calculated for each individual by summing the number of BMI-increasing alleles across the 8 loci. Weight and height were measured and dietary data were collected using self-administered questionnaires. Among meal skippers, the difference in BMI between high-GRS and low-GRS (<8 and ≥8 BMI-increasing alleles) groups was 0.90 (95% CI 0.63,1.17) kg/m2, whereas in regular eaters, this difference was 0.32 (95% CI 0.06,0.57) kg/m2 (p
interaction = 0.003). The effect of each MC4R rs17782313 risk allele on BMI in meal skippers (0.47 [95% CI 0.22,0.73] kg/m2) was nearly three-fold compared with regular eaters (0.18 [95% CI -0.06,0.41] kg/m2) (p
interaction = 0.016). Further, the per-allele effect of the FTO rs1421085 was 0.24 (95% CI 0.05,0.42) kg/m2 in regular eaters and 0.46 (95% CI 0.27,0.66) kg/m2 in meal skippers but the interaction between FTO genotype and meal frequencies on BMI was significant only in boys (p
interaction = 0.015). In summary, the regular five-meal pattern attenuated the increasing effect of common SNPs on BMI in adolescents. Considering the epidemic of obesity in youth, the promotion of regular eating may have substantial public health implications.
In workplace obesity prevention programs, it might be beneficial to improve the psychosocial work environment and promote healthy behaviors simultaneously.
