Explaining the complex impact of the Covid-19 pandemic on children with overweight and obesity: a comparative ecological analysis of parents' perceptions in three countries

BACKGROUND

The Covid-19 pandemic has changed children's eating and physical activity behaviours. These changes have been positive for some households and negative for others, revealing health inequalities that have ramifications for childhood obesity. This study investigates the pandemic's impact on families of children aged 2-6 years with overweight or obesity.

METHODS

Drawing on interviews conducted as part of a randomised controlled trial (RCT) for childhood obesity, thematic analysis was used to examine how parents of pre-schoolers perceived changes in their eating, screentime and physical activity behaviours between the first and second waves of Covid-19. Parents (n = 70, representing 68 families) were interviewed twice during a period of 6 months in three countries with markedly different pandemic policies - Sweden, Romania, and Spain. The analysis is informed by Bronfenbrenner's ecological systems theory, which embeds home- and school-based influences within societal and policy contexts.

RESULTS

The findings show that, although all participants were recruited from an RCT for families of children with excess weight, they reported different responses to the pandemic's second wave, with some children engaging in healthier eating and physical activity, and others engaging in comfort eating and a more sedentary lifestyle. Differences in children's obesity-related behaviours were closely related to differences in parents' practices, which were, in turn, linked to their emotional and social wellbeing. Notably, across all sites, parents' feeding and physical activity facilitation practices, as well as their emotional and social wellbeing, were embedded in household resilience. In resilient households, where parents had secure housing and employment, they were better able to adapt to the challenges posed by the pandemic, whereas parents who experienced household insecurity found it more difficult to cope.

CONCLUSIONS

As the Covid-19 pandemic is turning into a long-term public health challenge, studies that address household resilience are crucial for developing effective prevention and treatment responses to childhood obesity.

Psychosocial predictors and moderators of weight management programme outcomes in ethnically diverse obese youth

BACKGROUND

An important area of research in childhood obesity is the identification of factors that predict or moderate the responses to obesity intervention programmes, yet few studies have examined the impact of self-esteem and family functioning on obesity treatment outcomes.

OBJECTIVES

We sought to determine whether baseline self-esteem and family functioning predicted or moderated childhood obesity intervention outcomes at 6 months.

METHODS

From 2009 to 2011, seventy-five 10-16 year old, racially/ethnically diverse obese youths with abnormal glucose tolerance were randomized to 6 months of an intensive family-based obesity lifestyle intervention (Bright Bodies) or routine outpatient Clinic Care. We examined youth self-concept, parent-rated family functioning and 6-month outcomes (youths' glucose tolerance, weight, body mass index and percent fat). We set the significance threshold as P ≤ 0.05 for moderator and predictor analyzes.

RESULTS

Having poor family functioning and self-concept scores indicating high anxiety and low self-esteem at baseline predicted poor 6-month outcomes overall (Bright Bodies and Clinic Care groups combined). Additionally, baseline self-esteem and family functioning moderated treatment effects such that Bright Bodies outperformed Clinic Care in youths with low self-esteem and poorly functioning families, whereas youths with high self-esteem and high-functioning families did similarly well with either intervention.

DISCUSSION

Our findings suggest intensive family-based lifestyle programmes are particularly beneficial for youth with low self-esteem and poorly functioning families.

Inequality and childhood overweight and obesity: a commentary

Statements on childhood overweight and obesity (COO) have focused on different avenues for prevention and treatment, critical stages of the life cycle, including pregnancy and lactation, individual, family, school and community-based interventions, multidisciplinary family programmes and multicomponent interventions. This commentary is concerned with the less-addressed relationship between COO and inequality. It describes current global patterns of inequality and COO and the ways in which those inequalities are linked to COO at micro-level, meso-level and macro-level. It then describes current programmatic approaches for COO inequality, preventive and medical, and considers important pitfalls in the framing of the problem of COO and inequality. It ends with describing how childhood and adolescent overweight and obesity prevention and treatment programmes might be formulated within broader socio-political frameworks to influence outcomes.

Low grandparental social support combined with low parental socioeconomic status is closely associated with obesity in preschool-aged children: a pilot study

While the influence of parental socioeconomic status (SES) on children's weight status is well known, the impact of other family-related aspects such as parental and grandparental social support is less understood. This study investigates the importance of parents' SES and social support (functional and structural) for weight status in a clinical sample of preschoolers 4-6 years old with obesity (n = 39, 56% girls; 73% of parents were overweight/obese, 50% were of non-Swedish origin). Linear regression analyses, simple and multiple, were performed on SES and social support with child BMI SDS (body mass index standard deviation score) as the dependent variable. The results show that parents' income and low emotional support from paternal grandparents were significantly associated with more severe obesity. The association between parental income and the child's BMI SDS was stronger among parents who had low emotional support from their own parents. In conclusion, grandparental social support may be protective against childhood obesity.

Infant growth is associated with parental education but not with parental adiposity - Early Stockholm Obesity Prevention Project

AIM

To explore the simultaneous impact of parental adiposity and education level on infant growth from birth to 12 months, adjusting for known early-life risk factors for subsequent childhood obesity.

METHODS

Baseline data for 197 one-year-old children and their parents, participating in a longitudinal obesity intervention, were used. Obesity risk groups, high/low, were defined based on parental body mass index (n = 144/53) and parental education (n = 57/139). Observational data on infant growth between 0 and 12 months were collected. The children's relative weight (body mass index standard deviation score) at 3, 6 and 12 months and rapid weight gain 0-6 months were analysed in regression models, with obesity risk as primary exposure variables, adjusting for gestational weight gain, birth weight, short exclusive breastfeeding and maternal smoking.

RESULTS

Relative weight at 3, 6 and 12 months was associated with low parental education but not with parental adiposity. No significant associations were observed with rapid weight gain. None of the early-life factors could explain the association with parental education.

CONCLUSION

Low parental education level is independently associated with infant growth, whereas parental obesity does not contribute to a higher weight or to rapid weight gain during the first year.

Self-esteem in a clinical sample of morbidly obese children and adolescents

AIM

To study self-esteem in clinical sample of obese children and adolescents.

METHODS

Obese children and adolescents aged 8-19 years (n = 107, mean age 13.2 years, mean BMI 32.5 [range 22.3-50.6], mean BMI z-score 3.22 [range 2.19-4.79]; 50 boys and 57 girls) were referred for treatment of primary obesity. Self-esteem was measured with a validated psychological test with five subscales: physical characteristics, talents and skills, psychological well-being, relations with the family and relations with others. A linear mixed effect model used the factors gender and adolescence group, and the continuous covariates: BMI z-scores, and BMI for the parents as fixed effects and subjects as random effects.

RESULTS

Age and gender, but neither the child's BMI z-score nor the BMI of the parents were significant covariates. Self-esteem decreased (p < 0.01) with age on the global scale as well as on the subscales, and was below the normal level in higher ages in both genders. Girls had significantly lower self-esteem on the global scale (p = 0.04) and on the two subscales physical characteristics (p < 0.01) and psychological well-being (p < 0.01).

CONCLUSION

Self-esteem is lower in girls and decreases with age. In treatment settings special attention should be paid to adolescent girls.

Physical activity-key issues in treatment of childhood obesity

Changes in physical activity with the aim of increasing energy expenditure are usually an important component of childhood obesity treatment. Physical activity also has several other aspects that are positive for the obese child's health, such as improving the metabolic profile and psychological well being. The aim of this paper is to give a short review of what we know about physical activity in paediatric obesity treatment. In addition, practical recommendations will be presented which a health care provider can suggest to obese children and their families with a special focus on daily activity, participation in physical education classes and sports, sedentary behaviours, active commuting to school and how to get family and friends involved in supporting the child.
