“…Awareness of this potential risk may contribute to the higher burden among parents of overweight/obese children in the study. Nevertheless, the proportion of children with overweight/obesity is similar to that found in the general population in the same age range (Bygdell et al, ). Further studies are needed to explore the impact of overweight/obesity on perceived parental burden for parents of children affected with haemophilia.…”

Aims and objectives To describe the perceived burden on parents of children with severe or moderate haemophilia and the impact of sociodemographic aspects and the child's medical condition on this. Background Parents of children with haemophilia face a multitude of demands. The child needs frequent intravenous injections, hospital visits, extra supervision and care. The child's illness and related management might have psychosocial effects on the parents. Design A multicentre, cross‐sectional study. Methods Caregiver burden was evaluated in 102 parents of children with haemophilia, using the HEMOCAB questionnaire which consists of 54 items divided into 13 domains which are to be answered on a 5‐point Likert scale. To assess the impact of sociodemographic aspects and clinical data on parental burden, linear regression analyses were undertaken. The study followed the STROBE checklist throughout the research process. Results Greater burden was seen in parents of children with past or present inhibitors, in parents of younger children, if a family member administered the clotting factor and in parents of children with overweight/obesity. No significant differences in burden were observed for type of haemophilia, if the child had bleeding in the past 12 months, if the child self‐infused, had another family member with haemophilia or if the parent had more children. Conclusions Parental perceived burden can be negatively affected by the child's medical condition; our results underline that healthcare professionals need to be aware of increased parental burden if the child is young, has or had inhibitors and has overweight/obesity. Relevance to clinical practice More psychosocial support from the healthcare professionals needs to be directed towards parents of younger children and particularly the parents of young children with inhibitors, thus decreasing the parental burden. Parental burden may be reduced if healthcare professionals more actively treat overweight and refer children to appropriate specialists.

“…The age interval of the present cohort was 52–68 years at the end of follow-up (December 31, 2013) and thus stroke risk later in life could not be studied. It should be emphasized that since the present cohort was born in 1945–1961, the prevalences of obesity are lower (1.3% at 8 years of age and 0.9% at 20 years in the present study), while the corresponding figures in more recent years are higher, 7.9% at 8 years of age 28 and 3.8% at age 20 in a study from the military service conscription register. 29 Thus the present study predates the childhood obesity epidemic and today's obesogenic environment may further enhance the observed associations with adult stroke events.…”

BMI increase through puberty and adolescence is associated with risk of adult stroke

et al. 2017

Objective:To evaluate the contribution of prepubertal childhood body mass index (BMI) and BMI change through puberty and adolescence, 2 distinct developmental BMI parameters, for risk of adult stroke in men.Methods:In this population-based study in Gothenburg, Sweden, men born in 1945–1961 with information on both childhood BMI at age 8 and BMI change through puberty and adolescence (BMI at age 20–BMI at age 8) were followed until December 2013 (n = 37,669). Information on stroke events was retrieved from high-quality national registers (918 first stroke events, 672 ischemic stroke events [IS], 207 intracerebral hemorrhage events [ICH]).Results:BMI increase through puberty and adolescence (hazard ratio [HR] 1.21 per SD increase; 95% confidence interval [CI] 1.14–1.28), but not childhood BMI, was independently associated with risk of adult stroke. Subanalyses revealed that BMI increase through puberty and adolescence was associated with both IS (HR per SD increase 1.19; 95% CI 1.11–1.28) and ICH (HR per SD increase 1.29; 95% CI 1.15–1.46). High BMI increase during puberty was strongly associated with increased risk of adult hypertension (odds ratio per SD increase 1.35; 95% CI 1.32–1.39).Conclusions:BMI increase through puberty and adolescence is associated with risk of adult IS and ICH in men. We propose that greater BMI increases during puberty contribute to increased risk of adult stroke at least partly via increased blood pressure.

“…There was an inverse association between childhood BMI and age at PHV in the present study population born 1947 to 1996 below, but not above, a threshold at 17.71 (eFigure 3 in the Supplement ). Given that childhood BMI increased during the same period, 11 we next wanted to determine the secular trend of earlier age at PHV independent of childhood BMI . When we included age at PHV and childhood BMI (median, 15.8; range 12.3-29.2) in the same linear regression model, we found that the association between birth year and age at PHV was slightly attenuated but remained significant; the age at PHV was 1.2 months earlier per decade increase during the study period (−0.10 years per decade increase in birth year; 95% CI, −0.12 to −0.07; Figure 3 ).…”

“… 10 Moreover, we have reported a pronounced increase in mean childhood BMI among 8-year-old boys from the 1940s until now. 11 Here, we address the earlier mentioned knowledge gap regarding male pubertal timing and hypothesize that there is a secular trend for earlier pubertal timing in boys that can be partially explained by childhood BMI. This study’s aim was to investigate the association between birth year and changes in male pubertal timing independent of changes in childhood BMI.…”

Secular Trends in Pubertal Growth Acceleration in Swedish Boys Born From 1947 to 1996

IMPORTANCE A secular trend for earlier menarcheal age has been established in girls but there are few studies of pubertal timing for boys. OBJECTIVE To determine if there is a secular trend for earlier pubertal timing among boys. DESIGN, SETTING, AND PARTICIPANTS For this population-based retrospective cohort study conducted in Gothenburg, Sweden, we collected heights and weights from school health records for boys born consecutively from January 1 and onwards in 1947 and every 5 years from 1951 to 1996 (n = 375 for each birth cohort from 1947-1991, n = 340 for the birth cohort in 1996, and n = 4090 for the total cohort). We estimated age at the peak height velocity (PHV), the maximum growth velocity during puberty, and childhood body mass index (BMI) at age 8 years for all study participants. The data were analyzed during 2018 and 2019. Boys were eligible if they had a complete personal identity number and data to calculate their age at PHV and childhood BMI. Approximately 2.4% of the original study population was excluded because they lacked a personal identity number, and in the remaining study population, 4090 (69%) had sufficient data to calculate childhood BMI and age at PHV. EXPOSURES The exposure was birth year and a potential confounding factor was childhood BMI. MAIN OUTCOMES AND MEASURES The outcome was age at PHV. RESULTS Of the 4090 participants, most were white and the mean (SD) age at PHV was 13.9 (1.1) years. A linear regression model revealed a significant association between year of birth and age at PHV. Age at PHV was 1.5 months earlier for every decade increase in birth year (95% CI, −1.72 to −1.19; P < .001). After adjusting for childhood BMI, age at PHV was 1.2 months earlier per decade increase in birth year (95% CI, −1.41 to −0.89). All analyses were repeated in the subgroup of boys born in Sweden and with parents born in Sweden with similar results, indicating that the secular trend was not explained by demographic changes in the population between 1947 and 1996. CONCLUSIONS AND RELEVANCE We provide evidence of a secular trend for earlier pubertal timing in boys that is partially explained by an increased childhood BMI, but other factors that are unknown contribute.

The rise and the recent decline of childhood obesity in Swedish boys: the BEST cohort

Abstract: This long-term study captures both the rise and the recent decline of childhood obesity. As childhood obesity is strongly associated with subsequent adult obesity, we anticipate a similar reduction in adult obesity during the coming decades in Swedish men.
