Associations between socioeconomic status, home food availability, parental role-modeling, and children's fruit and vegetable consumption: a mediation analysis

Fruit and vegetable consumption among children in Saudi Arabia: Predictors and associations with dietary intake

BACKGROUND

Data exploring factors related to the consumption of fruits and vegetables (F&V) among children in Saudi Arabia are lacking. The present study aimed to evaluate F&V consumption among Saudi children. Predictors of F&V intake and associations with dietary intake were also explored.

METHODS

Cross-sectional data of 424 Saudi children (6-12 years) were collected from their mothers using an online survey. Phone interviews were conducted with mothers and children to provide data on dietary intake of children.

RESULTS

Most children included in the study (92.2%, n = 391) consumed less than five servings of F&V per day. Region of residency (B = -0.14, SE = 0.06, 95% confidence interval [CI] = -0.25 to -0.02, p = 0.019), paternal education level (B = 0.52, SE = 0.14, 95% CI = 0.24-0.79, p < 0.001) and family monthly income (B = 0.15, SE = 0.07, 95% CI = 0.01-0.29, p = 0.034) predicted the intake of F&V. Food neophobia and food pickiness also predicted the intake of F&V (B = -0.16, SE = 0.06, 95% CI = -0.27 to -0.05, p = 0.005 and B = -0.24, SE = 0.06, 95% CI = -0.36 to -0.12, p < 0.001, respectively). Children's intake of F&V positively predicted the intake of fibre, potassium, phosphorus, magnesium, iodine and vitamin C.

CONCLUSIONS

Limited intake of F&V was observed among Saudi children. F&V consumption was found to be associated with a number of sociodemographic factors, including region of residency, paternal education level and family income, as well as children's food neophobia and pickiness. Children's intake of F&V predicted higher intake of fibre, potassium, phosphorus, magnesium, iodine and vitamin C, suggesting that F&V consumption may contribute to improved intake of key nutrients in children.

Social desirability bias is related to children's energy intake in a laboratory test meal paradigm

Dietary intake is notoriously difficult to measure in children. Laboratory test meals address some of the methodological concerns of self-report methods, but may also be susceptible to social desirability bias, referring to the tendency for individuals to adjust their behaviors in order to be perceived more positively. The aim of the current study was to evaluate whether social desirability bias was associated with children's energy intake during a laboratory test meal, and whether this association varied by food type (total caloric intake, snack food intake, fruit/vegetable intake) and sex. A total of 82 children (M age = 9.45 ± 0.85; 50 % girls; 84.1 % rural; 85.4 % White) completed several surveys, including the Children's Social Desirability Scale and had their body composition measured. At lunchtime, they were granted access to a multi-array test meal (>5000 kcal). After adjusting for lean mass, fat mass, depressive symptoms, and parental food restriction, children who reported higher social desirability bias consumed fewer calories from snack foods (B = -11.58, p = .009, semi-partial correlation = -0.28). Boys with higher social desirability bias consumed less calories from fruits and vegetables (B = -6.47, p = .010, semi-partial correlation = -0.411); this association was not significant in girls. The desire to be perceived in a positive manner may influence children's eating behaviors in experimental paradigms. Replication studies with larger, more diverse pediatric samples are needed, as are strategies to reduce the effects of social desirability bias on test meal intake in order to enhance the validity of this dietary assessment approach.

Factors Associated with Daily Fruit and Vegetable Intakes among Children Aged 1-5 Years in the United States

To describe child, caregiver, and household characteristics associated with fruit and vegetable intakes among US children aged 1-5 years, we examined fruit and vegetable intakes (less than daily vs. daily) using data from the 2021 National Survey of Children's Health among children aged 1-5 years. Multiple logistic regression provided adjusted odds ratios for factors associated with (1) daily fruit and (2) daily vegetable intakes. Among children aged 1-5 years, 68% (n = 11,124) consumed fruit daily, and 51% (n = 8292) consumed vegetables daily. Both daily fruit and daily vegetable intake were associated with child age, child race and ethnicity, and frequency of family meals. For example, children who ate a family meal 4-6 days/week (aOR 0.69; 95% CI 0.57, 0.83) or 0-3 days/week (aOR 0.57; 95% CI 0.46, 0.72) were less likely to consume fruit daily compared to children who had a family meal every day. Participation in food assistance programs, food insufficiency, and household income were not significantly associated with odds of daily fruit or daily vegetable intake in the adjusted models. Several factors were associated with daily fruit and vegetable intake among children aged 1-5. Strategies aimed at increasing fruit and vegetable consumption in early childhood may consider these child, caregiver, and household characteristics. Pediatric healthcare providers, early childhood education centers, and families of young children may be important partners in this work.

Associated factors with mycotoxin exposure in Spanish population

Human exposure to mycotoxins is a global concern since filamentous fungi can contaminate food and feed from crops to ready-to-eat meals. Human urine biomonitoring is a widely used technique to evaluate mycotoxins exposure, as an alternative to food correlation studies. The aim of this study is to describe human exposure to mycotoxins and to investigate the associated sociodemographic, lifestyle and dietary variables. Participants were 540 women from the Valencia (Spain) cohort of the Spanish Childhood and Environment Project (INMA). A validated multi-mycotoxin method using HPLC-Q-TOF-MS was applied to determine the concentration of ten selected mycotoxins: Enniatin A, Enniatin B, Enniatin A1, Enniatin B1, Beauvericine, Aflatoxin B1, Aflatoxin B2, Aflatoxin G1, Aflatoxin G2 and Ochratoxin A. A simultaneous untargeted screening of mycotoxins and their metabolites has been performed. Mycotoxins associations were assessed by bivariate and multivariate regression models using participants' sociodemographic, lifestyle and dietary data collected through questionnaires. Mycotoxins were detected in 81% of urine samples. The method quantified mycotoxins concentrations in up to 151 samples. Most quantified mycotoxins were: Enniatin B [% of detection (concentration range)] = 26% (1.0-39.7 ng/mg) and Enniatin B1 = 7% (0.5-14.4 ng/mg). Besides the ten-targeted mycotoxins, other mycotoxins and metabolites were studied, and higher incidence was observed for Deepoxy-deoxynivalenol (45%), Ochratoxin B (18%) and Ochratoxin α (17%). Higher mycotoxins concentrations were associated with rural areas as well as with participants belonged to lower social class, beer, light sodas and fruit juice consumers. On the contrary, higher processed meat intake was related to lower mycotoxins' levels. Studies are required to better evaluate the exposure to mycotoxins from food and their environmental relationships.

Research on the Impact of Consumer Experience Satisfaction on Green Food Repurchase Intention

With the continuous improvement in people's living standards and the change in consumption concept, green food is favored by more and more consumers. Consumer repurchase behavior is a necessary condition to activate the market, expand the consumption scale and stabilize the continuous growth of the market. Repurchase intention is the most direct factor affecting consumers' green food repurchase intention. Therefore, it is necessary to study consumers green food repurchase intentions. This study collects data from 303 consumer surveys on green food consumption to explore the impact of consumer satisfaction with consumption experience on green food repurchase intention and further explore the mechanisms and influence boundaries. The results show that (1) consumer experience satisfaction positively affects green food repurchase intention; (2) consumer experience satisfaction can improve consumers' green food repurchase intention through consumer perceptions of social value, green self-efficacy and warm glow; (3) the higher the degree of consumer inertia, the stronger the influence of green self-efficacy and warm glow on consumers' green food repurchase intention; and (4) the higher the degree of consumer subjective norms, the stronger the influence of consumer perceived social value, green self-efficacy and warm glow on the consumer's green food repurchase intention. This study provides a new perspective and theoretical framework for promoting consumers' green food repurchase intention, and it may have certain theoretical significance and practical impact on green food market growth, sustainable carrying of the ecological environment and high-quality development of agriculture.

Association of Maternal Feeding Style with Fruit and Vegetable Consumption in Saudi Preschoolers: A Nationwide Cross-Sectional Study

Parental feeding style (PFS) remarkably influences fruit and vegetable (F&V) consumption in preschoolers. This study aimed to determine the association between PFS and preschoolers' F&V consumption, as influenced by socioeconomic factors. A nationwide cross-sectional study was conducted among 1418 mothers of children aged 3-5 years in Saudi Arabia. Multinomial logistic regression model analysis was performed to assess the association between PFS and children's daily F&V intake using the Parental Feeding Style Questionnaire. The influence of socioeconomic factors on this association was also evaluated. For mothers with university degrees, encouragement, emotional, and instrumental feeding enhanced their children's intake of F&Vs, fruits, and vegetables, respectively. Children from families earning SAR >10,000 monthly had increased F&V intake with encouragement feeding and increased fruit intake with emotional feeding. However, F&V intake was reduced in children of working mothers with controlling feeding styles. Breastfeeding for <6 months was associated with increased F&V intake through emotional feeding. The most prevalent feeding style was encouragement, followed by emotional, with control and instrumental styles being less common. This study provides strong evidence on the association between PFS and daily F&V intake in Saudi preschoolers. Interventional and longitudinal studies on PFS are required to confirm these findings.
