“…The remaining 23 studies that examined the relationship between grandparental child care and children's body weight status were included in the review. 16,17,[19][20][21][22][23][24][25][26][27][28][29][32][33][34][35][36][37][38][39][40][41] Fourteen studies were included in the meta-analyses, as shown in Table 4 (4 studies on BMI z-scores 32,33,37,38 and 10 studies on childhood overweight/obesity risk 19,[22][23][24][25][26]28,[34][35][36] ). Table 2 summarizes the basic characteristics of the 23 included studies.…”

“…They also found that grandparents' involvement in caregiving was inversely associated with BMI z-scores among children 6-10 years of age from certain Hispanic origin groups. 17 Morita et al 38 reported grandparents' co-residence to be inversely associated with BMI z-scores among children 6-7 years of age. Lindberg et al 39 reported that receiving emotional support from paternal grandparents was inversely associated with BMI z-scores among children 4-6 years of age.…”

Objective: This study systematically reviewed the scientific literature on the relationship between grandparental child care and childhood obesity. Methods: Keyword/reference search was performed in CINAHL, PsycINFO, PubMed, and Web of Science. Meta-analysis was conducted to estimate the pooled effect of grandparental child care on children's weight outcomes. Results: A total of 23 studies were identified, including 9 longitudinal, 9 cross-sectional, 2 case-control, and 3 qualitative studies. Eight studies were conducted in China, five in Japan, three in the United Kingdom, two in the United States, and one in five other countries each. Twelve studies focused on grandparents' roles as a main caregiver in the family, and seven on grandparents' coresidence. Data from 14 studies were used in meta-analysis, 10 focusing on childhood overweight/obesity and the other 4 on children's BMI z-scores. Meta-analysis found that grandparental child care was associated with a 30% (95% confidence interval = 21-40) increase in childhood overweight/obesity risk. Grandparental child care was not associated with children's BMI z-scores after correcting for publication bias. Meta-regressions revealed no difference in the estimated effect of grandparental child care on children's weight outcomes by country or grandparents' specific roles (main caregiver in the family vs. co-residence). Conclusions: Preliminary evidence links grandparental child care to elevated risk of childhood overweight/obesity, but not BMI z-scores. Future research should focus on a specific child age group within a country, adopt systematic and field-validated measures on grandparental child care, and elucidate the pathways linking grandparental child care to children's weight outcomes.

“…The Adachi Child Health Impact of Living Difficulty (A-CHILD) project was established in 2015 to evaluate the determinants of health among children in Adachi City, Tokyo, Japan [30][31][32]. We used data from the 2018 wave of the A-CHILD study.…”

“…Children's physical activity was assessed using the frequency of physical activity for 30 min or more during the week (never/rarely, 1-2 times/week, 3-4 times/week, or ≥5 times/week). Children's eating behavior included frequency of vegetable intake (twice/day, once/day, or <3 times/week), frequency of breakfast intake (every day, often, or rarely/never), and snacking habits (no snacking, snacking at a set time (controlled), or snacking freely) [32]. Household characteristics included the caregiver's marital status (married or living with partner, single, divorced, or widowed), the child having siblings (yes or no), cohabitation with the child's grandparents (yes or no), and annual household income (<3.00, 3.00-5.99, 6.00-9.99, or ≥10.0 million yen).…”

This study aimed to investigate the association between the frequency of home cooking and obesity among children in Japan. We used cross-sectional data from the Adachi Child Health Impact of Living Difficulty study, a population-based sample targeting all fourth-grade students aged 9 to 10 in Adachi City, Tokyo, Japan. Frequency of home cooking was assessed by a questionnaire for 4258 caregivers and classified as high (almost every day), medium (4-5 days/week), or low (≤3 days/week). School health checkup data on height and weight were used to calculate body mass index z-scores. Overall, 2.4% and 10.8% of children were exposed to low and medium frequencies of home cooking, respectively. After adjusting for confounding factors, children with a low frequency of home cooking were 2.27 times (95% confidence interval: 1.16-4.45) more likely to be obese, compared with those with a high frequency of home cooking. After adjustment for children's obesity-related eating behaviors (frequency of vegetable and breakfast intake and snacking habits) as potential mediating factors, the relative risk ratio of obesity became statistically non-significant (1.90; 95% confidence interval: 0.95-3.82). A low frequency of home cooking is associated with obesity among children in Japan, and this link may be explained by unhealthy eating behaviors.

“…Family and the home environment are well-established sources of influence on children’s eating habits, especially in early and middle childhood [6]. While poor parental feeding practices such as using unhealthy food to reward desirable child behavior [7] and overfeeding [8] can adversely affect children’s dietary behaviors and their health, there is growing evidence to suggest that grandparents play an increasingly important role in influencing their grandchildren’s feeding practices [8,9,10,11,12,13,14,15,16].…”

Feeding-Related Knowledge, Attitudes, and Practices among Grandparents in Singapore

et al. 2019

Childhood obesity is a growing concern worldwide. Though multifactorial, the family environment exerts significant influence on children’s eating habits. Grandparents are increasingly involved as caregivers and they can significantly influence their grandchildren’s eating habits. Yet, literature on this topic is lacking. This exploratory sequential mixed methods study (qualitative interview and interviewer-administered questionnaire) aims to understand grandparents’ knowledge, attitudes, and practices on the feeding of their grandchildren in Singapore. A total of 11 interview participants and 396 questionnaire respondents with at least one grandchild, aged 12 years and below were included. Qualitative interviews informed the questionnaire development. Responses to interview questions about knowledge, attitudes, and practices revealed sub-themes such as knowledge on the impact of feeding, attitude toward feeding role, and challenges to feeding. Of the 396 participants, 35% were primary caregivers (defined as the person who spends the most time with the grandchild and performs most of the caregiving tasks). Nutritional knowledge was fair (median score 5/8), with misconceptions centered around healthy feeding practices. Grandparents who were primary caregivers, female, Malay, and younger than 70 years old believed that they played an important role in feeding their grandchild (p < 0.05). Overall, 47.2% of the grandparents rarely or never set a maximum limit on the amount of unhealthy food eaten, of which 77.1% are non-primary caregivers. In comparison, primary caregivers tend to set a maximum limit to the amount of unhealthy food their grandchildren eat and choose a wide variety of food (p < 0.05). These findings support the need for further improvement of grandparents’ feeding knowledge and practices as part of tackling childhood obesity.
