Healthy Life Habits in Caregivers of Children in Vulnerable Populations: A Cluster Analysis

Intervention programs aimed at mitigating the effects of chronic noncommunicable disease (CNDs) focus on promoting healthy lifestyle habits (HLH), especially in the early stages of life. Because of this, different typologies of caregivers have been identified according to HLH during middle childhood and adolescence. However, the available studies have focused on aspects such as nutrition, physical activity, and rest, ignoring other HLHs that are equally important for children's well-being. Likewise, few studies address HLH during the first five years of life and how caregivers affect children's health. In a sample of 544 caregivers of children aged zero to five years from low-income Colombian communities, we established a typology of attitudes toward different HLHs. The results indicate the presence of three clusters that grouped caregivers with (1) positive attitudes toward all HLHs, (2) toward some HLHs, and (3) relatively low positive attitudes toward all HLHs. Membership in clusters with less positive attitudes toward HLHs was also found to be associated with low educational levels and living in rural areas. This study detected profiles of caregivers who may have unhealthy lifestyles, so the results would allow social workers to design differential interventions on HLHs in non-industrialized countries.

Surveys as a valid tool for assessing food safety knowledge amongst pregnant women in high-income countries: a rapid review

Pregnancy, being a vulnerable period, is the time when woman are most motivated to change their diet and lifestyle. Ensuring food safety during this susceptible time of life is essential for avoiding the related risks. Although a wealth of recommendations and guidelines have been issued for for pregnant women, further evidence is required regarding their effectiveness in implementing the knowledge and changing behaviour on food safety topics are needed. Surveys are often used as a research tool to investigate knowledge and awareness amongst pregnant women. Our main aim is to analyse and describe the results of an ad hoc research approach developed to characterise the main features of surveys identified in the PubMed database. The three major food safety issues - microbiological, chemical and nutritional- were analysed. We identified eight main key features to provide a summary of the evidence with a transparent and reproducible methodology. Our results help summarise the knowledge on the features of for pregnant women, by focusing on high-income countries over the last five years. We observed a high level of heterogeneity and methodological variability in food safety surveys. This is a novel approach that could be used to analyse surveys utilising a robust methodology. The outcomes are useful for guiding new survey design methodology and/or the modification existing surveys. Our findings could help to fill knowledge gaps by improving the use of innovative strategies for recommendations and guidelines on food safety for pregnant women. Non-high-income countries deserve separate and more comprehensive consideration.

Implementing a 'Vegetables First' Approach to Complementary Feeding

Purpose of Review

To provide a rationale for promoting a vegetables first approach to complementary feeding (CF), building on prior exposure to vegetable flavours experienced in utero and via breastfeeding (chemosensory continuity).

Recent Findings

Vegetables confer selective health benefits but population intakes are below recommendations globally; maternal intake of vegetables during both pregnancy and lactation promotes familiarity with some vegetable flavours. Building on this exposure, vegetables as a first food during CF further promote acceptance. However, experiments testing efficacy of a vegetables first approach to CF demonstrate increased liking and intake, some evidence of generalisability but little evidence of sustained effects beyond infancy.

Summary

The aim to increase the quantity and variety of vegetables eaten by children is both desirable, to improve nutrient quality of the diet, and achievable. However, longer, larger, randomised control trials are needed to evidence any longer term, sustainable benefits to liking and intake of vegetables.

Comparison of food and nutrient intake in infants aged 6-12 months, following baby-led or traditional weaning: A cross-sectional study

BACKGROUND

A baby-led approach to weaning (BLW) encompasses self-feeding and self-selecting graspable foods, offering an alternative to traditional weaning (TW). This cross-sectional study explored adherence to characteristics of BLW and differences in food group exposure and nutrient intake between babies following either TW or BLW.

METHODS

Nutritional data were collected via multiple-pass 24-h recall, following parental completion of an online survey.

RESULTS

Infants were grouped according to age (6-8 months; TW [n = 36] and BLW [n = 24]) and (9-12 months; TW [n = 24] and BLW [n = 12]). BLW babies were more likely to be breast fed (p = 0.002), consumed a higher percentage of foods also consumed by their mother (p = 0.008) and were fed less purees (p < 0.001) at 6-8 months. TW babies were spoon fed more (p ≤ 0.001) at all ages. Amongst babies aged 6-8 months, total intake (from complementary food plus milk) of iron (p = 0.021), zinc (p = 0.048), iodine (p = 0.031), vitamin B12 (p = 0.002) and vitamin D (p = 0.042) and both vitamin B12 (p = 0.027) and vitamin D (p = 0.035) from complementary food alone was higher in babies following TW. Compared to TW, BLW babies aged 6-8 months had a higher percentage energy intake from fat (p = 0.043) and saturated fat (p = 0.026) from their milk. No differences in nutrient intake were observed amongst infants aged 9-12 months. Few differences were observed between groups in their number of exposures to specific food groups.

CONCLUSIONS

TW infants had higher intakes of key micronutrients at 6-8 months, although there were few differences in nutritional intake at 9-12 months or food group exposure between babies following TW or BLW. BLW appears to be socially desirable. Guidance for parents is required, along with larger, longer-term studies, which explore the potential impact of BLW in later childhood.
