Temperament and eating self-regulation in young children with or at risk for obesity: An exploratory report

Early childhood executive control modulates negative affectivity's role in increasing adolescent body mass index trajectories

BACKGROUND

Executive control and temperament have been associated with pediatric obesity. However, interactions between these constructs in relation to future weight outcomes have not been investigated.

OBJECTIVE

This longitudinal study examined early childhood executive control, early temperament (negative affectivity and surgency), and their interactions as predictors of adolescent BMI trajectories.

METHODS

At age 5.25, children (N = 229) completed executive control tasks, and parents completed the Child Behavior Questionnaire to assess temperament. BMI was calculated annually between ages 14-17.

RESULTS

Greater early negative affectivity predicted more positive BMI growth. Although early childhood executive control was not associated with BMI growth, greater negative affectivity predicted greater BMI escalation at average and below average executive control abilities.

CONCLUSIONS

For children without robust executive control abilities early in development, negative affectivity may be a risk factor for accelerated adolescent BMI growth. Targeted assessment of early risk factors may be useful for childhood obesity prevention efforts.

Health-related behaviors and weight-related outcomes within sibling pairs: A systematic review

BACKGROUND

Siblings reciprocally contribute to mutual social and physical development. The aim of this review was to examine the health-related behaviors and weight-related outcomes within child-sibling pairs and to determine how these factors vary by sibling composition.

METHODS

Following the PRISMA guidelines, a systematic review of studies published since 2000 obtained from MEDLINE, CINAHL, PubMed, Cochrane Reviews, Web of Science, PsycINFO, Health and Wellness, and Science Direct was performed. The eligibility criteria for inclusion were: 1) peer-reviewed and published in English; 2) included children ages 2 to 20 and their siblings; and 3) explored health-related behaviors (i.e., diet) and/or weight-related outcomes (i.e., body weight) within child-sibling dyads.

RESULTS

A total of 13 studies were included in the review. The study findings are summarized according to three major themes: 1) sibling concordance in health-related behaviors and weight-related outcomes, 2) differences in health-related behaviors within weight-concordant/weight-discordant sibling dyads, and 3) influence of sibling composition on health-related behaviors and weight-related outcomes.

CONCLUSIONS

Family-based interventions for childhood obesity may benefit from including siblings as key family members in promoting children's health-related behaviors and preventing excessive weight gain. Future studies should explore variable sibling dynamics (e.g., adoptive siblings) in more culturally/racially diverse families to further explore the role of a sibling in a child's health.

IMPLICATIONS TO PRACTICE

The findings of this study may help healthcare providers in developing effective family-based obesity interventions for families with more than one child in their household.

Correlation of temperament characteristics and early functional exercise compliance in school-age children with limb fractures: Implication for clinical nursing care

Early functional exercise plays a very important role in the rehabilitation and nursing care of children with fractures. We aimed to evaluate the role of temperament characteristics in the early functional exercise compliance in school-age children with limb fractures, to provide evidence to clinical nursing care. School-age children with limb fractures admitted to our hospital from January 1, 2021 to June 30, 2022 were selected. We collected the general information, evaluated the temperament characteristics and their functional exercise compliance in school-age children. Correlation and regression analyses were conducted to assess the correlation of temperament characteristics and early functional exercise compliance. A total of 126 school-age children with limb fractures were finally included. There were 68, 36, and 22 children that were rated as easy-going, troublesome and initiate slow temperament, respectively. The children with easy-going temperament had the best early functional exercise compliance, followed by children with initiate slow temperament, and compliance of children with troublesome temperament was the worst. The reaction intensity factor in the temperament characteristics of school-age children with fracture was negatively correlated with early functional exercise compliance (P = .007). Reaction intensity was a risk factor for early functional exercise compliance in school-age children with fractures (P = .004). Health care providers must consider the influence of temperament characteristics on compliance in school-age children with fractures, and take targeted nursing measures according to different temperament characteristics of children to improve early functional exercise compliance in school-age children with fractures, so as to improve the functional recovery and prognosis of children.

Assessing the income-related inequality in obesity among the elderly in China: A decomposition analysis

Background

Obesity among the elderly imposes a significant health and economic burden. The purpose of this study was to measure the obesity prevalence and income-related inequality among older adults in China and to explore the determinants of the inequity.

Methods

Data were obtained from 4,541 older adults (60 years and older) participating in the China Family Panel Study, 2018. Obesity was defined as body mass index (BMI) ≥28 kg/m². Normalized concentration index and concentration curve were calculated to measure the income-related inequality. Decomposition analysis was used to measure the contribution of each factor to the overall unfairness.

Results

The prevalence of obesity among the respondents was 7.99%. The 95% confidence interval for the overall prevalence was 7.20-8.78%. The normalized concentration index of obesity in the elderly was 0.075 (95% confidence interval: 0.047-0.103), indicating that obesity was more concentrated among the rich (p < 0.05). Socioeconomic factors contributed the most to the overall inequality (68.73%). Health behavior factors explained 16.38% of the observed income-related inequality in obesity among the elderly in China.

Conclusions

In 2018, obesity was more concentrated among the elderly with higher incomes in China. The pro-poor income-related inequality was mainly due to the higher socioeconomic status of higher-income older adults. Health behaviors and psychosocial factors could also exacerbate the inequality. To prevent the heavy burden of obesity on the health and finances of older adults, more attention should be paid to those who are financially better off, especially those who smoke and are physically inactive, while extroverted older adults also need to be focused on. For developing countries, concern needs to be given to the obesity of the wealthy elderly as a result of economic development.

Infant temperament and mealtime distractions as predictors of preschool Children's bite speed during family mealtime

Eating behaviors are shaped at an early age, persist into adulthood, and are implicated in the development of physical health outcomes, including obesity. Faster bite speed has been identified as an obesogenic eating behavior, prompting researchers to examine child and family factors associated with children's variability in bite speed. Child temperament, involving phenotypes of reactivity and regulation, and distractions in family food contexts are fruitful areas of investigation, but few studies have examined the interplay among these factors and their associations with bite speed. To address the gap in the literature, we examined relations between early child temperament, family mealtime distractions, and children's observed bite speed. Caregiver report of child temperament at 3 months was measured using the Infant Behavior Questionnaire Very Short Form - Revised. Child mealtime distractions and bite speed were assessed using family mealtime videos that were collected during home visits when children were 18-24 months of age (n = 109). Results revealed that children who were reported to be higher on orienting/regulation at 3 months, and who were more distracted during mealtimes at 18-24 months, had relatively slower bite speeds. No significant interactions were found. The findings from this correlational study inform further investigations into the implications of early temperament and food contexts for the development of eating behaviors implicated in obesity risk.

Precision Food Parenting: A Proposed Conceptual Model and Research Agenda

Precision medicine, nutrition and behavioral interventions are attempting to move beyond the specification of therapies applied to groups, since some people benefit, some do not and some are harmed by the same therapy. Instead, precision therapies are attempting to employ diverse sets of data to individualize or tailor interventions to optimize the benefits for the receiving individuals. The benefits to be achieved are mostly in the distant future, but the research needs to start now. While precision pediatric nutrition will combine diverse demographic, behavioral and biological variables to specify the optimal foods a child should eat to optimize health, precision food parenting will combine diverse parent and child psychosocial and related variables to identify the optimal parenting practices to help a specific child accept and consume the precision nutrition specified foods. This paper presents a conceptual overview and hypothetical model of factors we believe are needed to operationalize precision food parenting and a proposed research agenda to better understand the many specified relationships, how they change over the age of the child, and how to operationalize them to encourage food parenting practices most likely to be effective at promoting healthy child food choices.
