Early childhood factors associated with obesity at age 8 in Vietnamese children: The Young Lives Cohort Study

Five Underutilized Ecuadorian Fruits and Their Bioactive Potential as Functional Foods and in Metabolic Syndrome: A Review

The Ecuadorian Amazon harbors numerous wild and cultivated species used as food, many of which are underutilized. This review explores the bioactive potential of five such fruits-Borojó (Alibertia patinoi); Chonta (Bactris gasipaes); Arazá (Eugenia stipitata); Amazon grape (Pourouma cecropiifolia), a wild edible plant; and Cocona (Solanum sessiliflorum)-and their applications against metabolic syndrome. This study highlights their health-promoting ingredients and validates traditional medicinal properties, emphasizing their significance in improving health and mitigating the effects of the Western diet. These fruits, integral to Ecuadorian cuisine, are consumed fresh and processed. Chonta is widely cultivated but less prominent than in pre-Hispanic times, Borojó is known for its aphrodisiac properties, Cocona is traditional in northern provinces, Arazá is economically significant in food products, and Amazon grape is the least utilized and researched. The fruits are rich in phenolics (A. patinoi, E. stipitata) and carotenoids (B. gasipaes, E. stipitata), which are beneficial in controlling metabolic syndrome. This study advocates for more research and product development, especially for lesser-known species with high phenolic and anthocyanin content. This research underscores the economic, cultural, and nutritional value of these fruits, promoting their integration into modern diets and contributing to sustainable agriculture, cultural preservation, and public health through functional foods and nutraceuticals.

Prevention of childhood overweight and obesity in Mongolia, the Philippines and Vietnam: identifying priority actions

Low- and middle-income countries are increasingly faced with a triple burden of malnutrition: endemic underweight, micronutrient deficiencies and rising prevalence of overweight. This study aimed to address existing knowledge gaps and to identify priority policy options in Mongolia, the Philippines and Vietnam. A landscape analysis approach was adopted using methods set out in a UNICEF global toolkit. Quantitative and qualitative data were compiled from a range of global and national sources on childhood overweight and obesity, risk factors and policy responses. Key informant interviews and validation workshops were undertaken with key food and nutrition stakeholders from government and non-government organizations to identify priority policy options for the prevention of overweight and obesity among children. Overweight and obesity among children are increasing in all three countries. Associated risk factors are related to maternal nutrition, birthweight, breastfeeding, as well as diets and physical activity shaped by increasingly obesogenic environments. Key informants identified undefined policy approaches, poor community understanding and food and beverage industry influence as barriers to addressing overweight and obesity. Key policy priorities include restricting the marketing of unhealthy food and beverages, unhealthy food and beverage taxation, introduction of front-of-pack nutrition labels and improving school nutrition environments. Mongolia, the Philippines and Vietnam are all facing an increasing burden of childhood overweight and obesity. Despite differing national contexts, similar environmental factors are driving this rise. A suite of evidence-based policies can effectively be introduced to address obesogenic environments.

Association between Food, Beverages and Overweight/Obesity in Children and Adolescents-A Systematic Review and Meta-Analysis of Observational Studies

A healthy diet is essential to prevent childhood obesity, however, adherence to a healthy diet is challenging. The aim of this study was to give a comprehensive overview of the literature investigaating associations between food and beverages and overweight/obesity in children and adolescents in order to identify dietary risk factors. A systematic search was performed in four databases and observational studies were included. Meta-analysis was performed using the random effect model. Sixty records met inclusion criteria and 14 different food or beverage categories were identified. A higher intake of sugar-sweetened beverages increased the odds of overweight/obesity by 1.20 (p < 0.05) (n = 26) and higher intake of fast food increased the odds of overweight/obesity by 1.17 (p < 0.05) (n = 24). Furthermore, higher intake of meat (OR 1.02, p < 0.05 (n:7)) and refined grains (OR 1.28, p < 0.05 (n:3)) was associated with an increased risk of overweight/obesity. In contrast, higher intake of whole grain (OR 0.86, p = 0.04 (n:5)) and more surprisingly sweet bakery (OR 0.59, p < 0.05 (n:3)) was associated with a decreased risk of overweight/obesity. In conclusion, a higher intake of sugar-sweetened beverages and a higher intake of fast food was identified as the primary dietary risk factors for overweight/obesity. Future research is needed to strengthen the generalizability of these results.

Childhood Overweight and Obesity in Vietnam: A Landscape Analysis of the Extent and Risk Factors

Tackling childhood overweight and obesity is critical not only to improve the health and well-being of children and adolescents, but also for entire populations and future generations. This paper provides the latest evidence on the extent of, and risk factors for, childhood overweight and obesity in Vietnam. The landscape analysis tool developed by the United Nations Children’s Fund (UNICEF) and World Health Organization (WHO) was used. A search for peer-reviewed articles in English on online databases was undertaken. Peer-reviewed Vietnamese articles were also retrieved from a range of sources. The prevalence of overweight among children aged under 5 years increased from 5.6% in 2010 to 7.4% in 2019. For overweight and obesity among children aged 5 to 19 years, prevalence rose from 8.5% and 2.5% in 2010 to 19% and 8.1% in 2020, respectively. Maternal malnutrition, gestational diabetes during pregnancy, and inadequate infant and young child feeding practices are all risk factors for early childhood overweight. Unhealthy diets, insufficient physical activity, and lack of sleep are among the risk factors for overweight and obesity among school aged children and adolescents. The prevention of overweight and obesity among Vietnamese children requires a whole-of-government, cross-sectoral approach to addresses the obesogenic environment that is negatively influencing the nutrition of children.

Systematic review and meta-analysis of breastfeeding and later overweight or obesity expands on previous study for World Health Organization

AIM

To update a systematic review and meta-analysis of the association of breastfeeding with overweight or obesity that had been commissioned by the World Health Organization. We also assessed the likelihood of residual confounding.

METHODS

Two independent reviewers searched MEDLINE, LILACS and Web of Science for manuscripts published between August 2014 and May 2021. Studies that only evaluated infants were excluded. Random-effects models were used to pool the estimates.

RESULTS

The review comprised 159 studies with 169 estimates on the association of breastfeeding with overweight or obesity, and most of the studies were carried out among individuals aged 1-9 years (n = 130). Breastfeeding protected against overweight or obesity (pooled odds ratio:0.73, 95% confidence interval:0.71; 0.76). And, even among the 19 studies that were less susceptible to publication bias, residual confounding and misclassification, a benefit was observed (pooled odds ratio:0.85, 95% confidence interval:0.77; 0.93). Among those studies that were clearly susceptible to positive confounding by socioeconomic status, a benefit of breastfeeding was observed even after adjusting for socioeconomic status (pooled odds ratio:0.76, 95% confidence interval: 0.69; 0.83).

CONCLUSION

Breastfeeding reduced the odds of overweight or obesity, and this association was unlikely to be due to publication bias and residual confounding.

Initial investigation of associations between feeding practices, eating behaviours, and weight status in Vietnamese children using modified questionnaires

AIMS

This cross-sectional study aims to extend the preliminary validation of the Feeding Practices and Structure Questionnaire (FPSQ) and Children's Eating Behaviour Questionnaire (CEBQ) in the Vietnamese context by examining associations between maternal feeding practices, child eating behaviours, and child weight status.

METHODS

Modified versions of the FPSQ and CEBQ were used to measure maternal feeding practices and child eating behaviours, respectively, in a sample of Vietnamese mothers of children within the age range of two to five years (n = 100). Children's weight-for-height z-scores (WHZs) were calculated using weight and height measurements obtained by clinicians. Pearson's correlation coefficients were used to examine bivariate associations between maternal feeding practices, child eating behaviours, and child WHZs. Significant variables were then entered into a multivariable regression model.

RESULTS

Child WHZs were associated with maternal persuasive feeding, and child slowness in eating, enjoyment of food/food responsiveness, and emotional undereating, but in multivariable regression analysis, only persuasive feeding (β = -0.44, p = 0.027) and slowness in eating (β = -0.39, p = 0.036) contributed significantly to the model.

CONCLUSIONS

The findings provide some evidence of construct validity for the modified questionnaires. Potential implications of dietary-related behaviours on weight status in preschool-aged children in Viet Nam are evident. However, further validation and analysis in larger datasets must be undertaken in order to examine these associations with increased certainty.

Prevalence and associated factors of overweight and obesity among primary school children: a cross-sectional study in Thanhhoa City, Vietnam

OBJECTIVE

To determine the prevalence and associated factors of overweight and obesity among primary school children (6-11 years old) in Thanhhoa city in 2021.

DESIGN

Cross-sectional study.

SETTING

Seven primary schools in Thanhhoa city, Vietnam.

PARTICIPANTS

782 children (and their parents).

PRIMARY AND SECONDARY OUTCOME MEASURES

Two-stage cluster random sampling was used for selecting children and data were collected from January to February 2021. A self-administrated questionnaire was designed for children and their parents. Children's height and weight were measured and body mass index (BMI)-for-age z-scores were computed using the WHO Anthro software V.1.0.4. Data were analysed using R software V.4.1.2. The associations between potential factors and childhood overweight/obesity were analysed through univariate and multivariate logistic regression analyses. Variables were selected using the Bayesian Model Averaging method.

RESULTS

The prevalence of overweight/obesity among primary school children in Thanhhoa city was 35.93% (overweight 21.61% and obesity 14.32%). The proportion of overweight girls was nearly equal to that of boys (20.78% and 22.52%, respectively, p=0.6152) while the proportion of boys with obesity was four times as many as that of girls (23.86% and 5.62%, respectively, p<0.0001). Child's sex was the factor significantly associated with childhood overweight/obesity. Boys had double the risk of being overweight/obese than girls (adjusted OR: aOR=2.48, p<0.0001). Other potential factors which may be associated with childhood overweight/obesity included mode of transport to school, the people living with the child, mother's occupation, father's education, eating confectionery, the total time of doing sports, and sedentary activities.

CONCLUSION

One in every three primary school children in Thanhhoa city were either overweight or obese. Parents, teachers and policy-makers can implement interventions in the aforementioned factors to reduce the rate of childhood obesity. In forthcoming years, longitudinal studies should be conducted to determine the causal relationships between potential factors and childhood overweight/obesity.
