Intergenerational transmission of dietary behaviours: A qualitative study of Anglo-Australian, Chinese-Australian and Italian-Australian three-generation families

Facilitators and barriers to healthful eating among adolescents in high-income countries: A mixed-methods systematic review

Adolescent obesity continues to be a public health challenge with poor quality diets contributing to its etiology. As part of the process to plan health promotion and policy interventions, understanding adolescents perceived facilitators and barriers to healthful eating is important. An integrative convergent mixed-methods systematic review was used to synthesize qualitative and quantitative evidence from studies among adolescents aged 10-19 years in high-income countries. Medline, Embase, PsycInfo, and Scopus were searched for peer-reviewed articles published between 2010 and 2023 and exploring adolescents' perspectives on healthful eating and contemporary contextual factors. Transformed quantitative data were integrated with qualitative data. Text was coded into subthemes and themes using an inductive approach. Key facilitators included health and physical appearance; motivation; taste; nutrition knowledge, awareness, and skills; nutrition education access; availability and accessibility of healthful foods; family; and social influences and digital media. Key barriers included taste and cravings for unhealthful foods; mood; lack of motivation, awareness, knowledge, and skills; high availability and low cost of unhealthful foods; peers and social influences; ineffective school policies; high density of fast-food outlets; unhealthful food advertising; digital influences; and time constraints. Social, behavioral, digital, and food environmental factors should be considered from an adolescent perspective in the design of education, health promotion, and policy interventions.

Eating Styles Profiles and Correlates in Chinese Postpartum Women: A Latent Profile Analysis

Postpartum women present a high risk of disordered eating behaviors, but the heterogeneity between groups was not identified. This cross-sectional study aimed to identify eating styles profiles in postpartum women and explore the correlates based on demographic characteristics and psychosocial factors. Questionnaires were administered to 507 Chinese postpartum women. Latent profile analysis (LPA) was conducted to identify eating styles profiles. Multinomial logistic regression was used to investigate the correlates of these profiles among postpartum women. The LPA identified three eating styles profiles: postpartum women with low emotional, external, and restrained eating (Profile 1, 6.9%); postpartum women with medium emotional, external, and restrained eating (Profile 2, 66.1%); and postpartum women with high emotional, external, and restrained eating (Profile 3, 27.0%). Compared to Profile 1, higher postpartum depression (PPD) and body mass index (BMI) were more likely to be associated with Profile 2 and Profile 3, whereas higher postpartum weight retention (PPWR) was more likely to be associated with Profile 1. Compared to Profile 2, higher PPD and BMI were more likely associated with Profile 3. Disordered eating behaviors in postpartum women with three eating styles were associated with BMI, PPD, and PPWR. This study can guide healthcare professionals in developing targeted interventions to improve maternal and child health globally.

How Shared Dietary Behaviors Within Asian American Families Are Influenced by Emotional Interaction Qualities: A Nationwide Cross-sectional Analysis

BACKGROUND

Asian American (AA) young adults face a looming diet-related non-communicable disease crisis. Interactions with family members are pivotal in the lives of AA young adults and form the basis of family-based interventions; however, little is known on the role of these interactions in shared family food behaviors. Through an analysis of 2021 nationwide survey data of 18-35-year-old AAs, this study examines how the quality of family member interactions associates with changes in shared food purchasing, preparation, and consumption.

METHOD

Interaction quality was assessed through 41 emotions experienced while interacting with family, and was categorized as positive (e.g., "I look forward to it"), negative (e.g., "I feel annoyed"), and appreciation-related (e.g., "I feel respected") interactions. Participants were also asked how frequently they ate meals, ate out, grocery shopped, and cooked with their family.

RESULTS

Among the 535 AAs surveyed (47.6% East Asian, 21.4% South Asian, 22.6% Southeast Asian), 842 unique family interactions were analyzed; 43.5% of interactions were with mothers, followed by siblings (27.1%), and fathers (18.5%). Participants most frequently ate meals with their family (at least daily for 33.5% of participants), followed by cooking (at least daily for 11.3%). In adjusted analyses, an increase in shared food behaviors was particularly associated with positive interactions, although most strongly with cooking together and least strongly with eating meals together; significant differences between ethnic subgroups were not observed.

CONCLUSION

Findings revealed the importance of family interaction quality when leveraging family relationships to develop more tailored, impactful AA young adult dietary interventions.

Education disrupts the intergenerational transmission of health disadvantage across three generations in China

This article utilizes survey data from the China Family Panel Studies (CFPS) to examine whether grandparents' health disadvantage have both direct and indirect effects on the health disadvantage of their grandchildren, and whether the completion of compulsory education by parents disrupts these intergenerational transmissions in China. The findings suggest that grandparents' health disadvantage significantly increases the probability of grandchildren's health disadvantage with and without controlling parental health disadvantage and other characteristics. Moreover, the study identifies a disruptive influence of parental education on this transmission process. Rigorous robustness tests, including the use of the Compulsory Education Law as an instrumental variable to control for unobserved factors, validate these results. Mechanism analysis shows that parents completing compulsory education contribute to improving their nutritional balance and adopting healthy behaviors, attaining higher social status, earning higher income, which ultimately reduce the probability of health disadvantage for both themselves and their children. These findings highlight the persistent intergenerational transmission of health disparities within families and emphasize the importance of enhancing individuals' education levels to disrupt this transmission. By doing so, it may be possible to mitigate health inequalities and disparities across the population.

A Multi-Stage Dyadic Qualitative Analysis to Disentangle How Dietary Behaviors of Asian American Young Adults are Influenced by Family

The dietary behaviors of Asian American (AA) young adults, who face a growing non-communicable disease burden, are impacted by complex socio-ecological forces. Family plays a crucial role in the lifestyle behaviors of AA young adults; however, little is known on the methods, contributors, and impact of familial dietary influence. This study aims to deconstruct the mechanisms of AA young adult familial dietary influence through a multi-perspective qualitative assessment. A five-phase method of dyadic analysis adapted from past research was employed to extract nuanced insights from dyadic interviews with AA young adults and family members, and ground findings in behavioral theory (the Social Cognitive Theory, SCT). 37 interviews were conducted: 18 young adults, comprising 10 different AA ethnic subgroups, and 19 family members (10 parents, 9 siblings). Participants described dietary influences that were both active (facilitating, shaping, and restricting) and passive (e.g., sharing foods or environment, mirroring food behaviors). Influences connected strongly with multiple SCT constructs (e.g., behavioral capacity, reinforcements for active influences, and expectations, observational learning for passive influences). Familial influence contributed to changes in the total amount, variety, and healthfulness of foods consumed. Intra-family dynamics were crucial; family members often leveraged each other's persuasiveness or food skills to collaboratively influence diet. AA family-based interventions should consider incorporating both passive and active forms of dietary influence within a family unit, involve multiple family members, and allow for individualization to the unique dynamics and dietary behaviors within each family unit.

Association between Maternal and Toddler Appetitive Traits in a Mexican Population

The Child Eating Behaviour Questionnaire for toddlers (CEBQ-T-Mex) and the Adult Eating Behaviour Questionnaire (AEBQ-Esp) measure appetitive traits (ATs) in children and adults, respectively, both validated for use in Spanish. ATs are inherited variations in appetite, present from birth, that are reasonably stable throughout childhood and can explain why some infants over- or undereat in response to environmental exposures. "Food approach" traits predispose to overweight while "food avoidance" traits provide protection, but little is known about the relationships between parents' and their toddler's ATs. The aim was to examine the associations between maternal and toddler appetitive traits, using the AEBQ-Esp and CEBQ-T-Mex, and to examine the associations between ATs and Body Mass Index z-scores (BMIz). Sociodemographic data and the weights and heights of mothers and toddlers (aged 12-36 months) were collected from a teaching hospital in Guadalajara, Mexico. Mothers completed both the AEBQ-Esp and the CEBQ-T-Mex. Direct correlations were found between the ATs of toddlers and their mother (p < 0.005), except for "Slowness in Eating" (SE), and only an inverse correlation was found between the "Satiety Responsiveness" (SR) of toddlers and their BMIz (r = -0.147; p = 0.007). These results suggest that ATs could potentially run in families. These may be useful targets for family-wide interventions to support the development and maintenance of healthy eating behaviours in childhood.

The Influence of Grandparents on Children's Dietary Health: A Narrative Review

PURPOSE OF REVIEW

To examine and synthesise recent evidence on the role of grandparents in shaping children's dietary health.

RECENT FINDINGS

The influence of grandparents on children's dietary health was evident across studies. Grandparents frequently provide their grandchildren with meals and snacks, and engage in many of the same feeding practices used by parents. Although grandparents report providing their grandchildren with healthy foods, the provision of treat foods high in sugar or fat was a common finding. This provision led to family conflict, with the indulgent behaviours of grandparents seen by parents as a barrier to healthy eating. Grandparents are exerting significant influence on child dietary health. Efforts are needed to ensure these care providers are considered key stakeholders in the promotion of healthy eating and are targeted in policies and programs addressing children's diets. Research that determines how to best support grandparents to foster healthy behaviours in children is critical.

Using the health belief model to understand the factors influencing the perceptions of people of Chinese ancestry about reducing salt consumption for hypertension prevention: A cross-sectional study

BACKGROUND

High-salt diets are linked to hypertension. Chinese people in Australia, are at increased risk of hypertension due to the combination of routine addition of high quantities of salt to food during cooking and high salt levels in processed western foods. There is a scarcity of salt-related behavioural studies on this population group. This study aimed to explore the habitual salt consumption of Chinese Australians and factors that influence their perceptions about sustaining salt-related behavioural changes for hypertension prevention.

METHOD

A cross-sectional descriptive study using an adapted Determinants of Salt-Restriction Behaviour Questionnaire was conducted on 188 Chinese Australians. A non-probability sampling method was used to attract participants from different parts of Australia. Statistical analyses such as descriptive analysis, t-tests and Pearson correlation tests were performed in the study.

RESULTS

Over 97% of participants did not measure the amount of salt added to their meals. Many participants reported that salt was added to their meals based on their experience (39.4%) and food taste (31.9%). Over 80% of participants did not know the recommended level of daily salt consumption. Although salt-related knowledge had no significant correlation with individuals' salty food taste preferences, there were significant correlations with the perceptions of the severity of disease and health benefits of reducing salt consumption (p = .001 and < .001 respectively). People with stronger salty taste preferences perceived a higher level of health threat than people with lighter salty taste preferences (p = .003).

CONCLUSION

Findings from this study show that knowledge about salt-reduction alone had no significant effects on salt-related behaviours. Adequate culturally relevant practice-based education in salt-reduction strategies may facilitate salt-related behavioural changes in Chinese Australians. Overall, single young Chinese Australian men with stronger salty taste preferences is the group who needs salt reduction interventions the most.

Eater-oriented knowledge framework for reducing salt and dietary sodium intake (scoping review)

Salt and dietary sodium are ubiquitously present in daily food practices and, at the same time, reducing salt intake presents an important public health issue. Given such an ambivalent position of salt in human diet, we argue that public health guidelines toward dietary sodium reduction require an eater-oriented knowledge framework. In this article we are making the first steps toward a flexible interdisciplinary database which would include nutritional, socio-economic, cultural, material, and socio-psychological determinants of salt consumption for comprehensive public health campaigns. We employ an explorative scoping review of academic articles and reports, limiting our review to the original data on salt or sodium consumption published in English or French between 2000 and 2022. We describe salt consumption as research object, identifying its representation in different research fields, data sources, methodologies, samples, and links with nutritional recommendations. We synthesize existing approaches via four eater-oriented categories: Socio-demographic and cultural descriptors of salt consumers; Knowledge, attitudes, and beliefs on nutritional norms; Salt practices associated with dietary or medical regimes; Salt materialities: interactions and contexts. In each category, we identify the dominant relational features, i.e., what kind of 'eater-salt' relation is being put forward. We thus build an interdisciplinary documentary base of dietary sodium consumption factors. We discuss the results, suggesting that comprehensive nutritional policies for global salt reduction require interdisciplinary eater-oriented data frameworks.

Dietary intake in children on the autism spectrum is altered and linked to differences in autistic traits and sensory processing styles

Diets of children and adolescents on the autism spectrum often differ when compared to their non-autistic peers. Most dietary studies have been limited by small sample sizes and rarely assess the heterogeneity of autism. Addressing this gap, this study compared the anthropometrics, dietary composition, dietary quality, and food variety of 154 Australian children and adolescents on the spectrum and 213 non-autistic children (71 siblings and 142 unrelated controls). Beyond the case-control approach, within-group comparisons assessed the influence of autism clinical presentations and sensory processing styles on body mass index (BMI) and measures of dietary intake among those on the spectrum. In this word first study of diet that included between-group comparisons with non-autistic peers (siblings and an unrelated comparison group) and within-autism group comparisons, we found that children on the spectrum consumed limited variety and lower quality of food and non-autistic siblings also ate comparably higher levels of energy-dense, nutrient poor food, and less diary. This may be due to autistic traits influencing family's diets or shared sensory sensitivities driving dietary intake. Within the autism group, higher autistic traits were associated with lower BMIs and a specific dietary pattern higher in simple carbohydrates and lower in unprocessed protein. Contrastingly, greater sensitivity to sensory stimuli was associated with a healthier diet. Increased age was linked to more varied diets but also diets higher in saturated fats and energy-dense, nutrient poor foods. Overall, this research highlights that potential mediators of dietary intake, such as familial influences, autistic traits, sensory processing styles, age and sex, need to be considered when assessing diet in the autistic population. LAY SUMMARY: In this study of dietary differences linked to autism, children, and teenagers on the spectrum ate fewer different foods and were less likely to eat recommended amounts of fruits and vegetables when compared to non-autistic siblings and unrelated children and teenagers. There were also family differences, in that those on the spectrum and their siblings ate more unhealthy foods and less dairy. Among those on the spectrum, dietary differences were linked to age, sex, autistic traits and sensory processing styles.

Deconstructing type 2 diabetes self-management of Australian Pacific Islander women: Using a community participatory research and talanoa approach

Community-based participatory research using culturally appropriate talanoa approaches provided the framework to explore diabetes self-management of Australian Pacific Islander (API) women living with type 2 diabetes in South-East Queensland. Data collection included interviews with key informants (21), in-depth interviews with API women with diabetes (10), talanoa group discussions (7) and monthly steering committee meetings. Using an interpretive-constructionist lens and the interpretations of community members, four cultural constructs in diabetes self-management emerged: self-identity, spirituality, stigma and denial, and structural factors. Self-identity connected the women to their Pacific heritage that framed their collective roles as primary caregivers in the community. This gave the women a strong sense of belonging and helped maintain cultural, family and relational connections which were important for their day-to-day management of diabetes. Although spirituality through religion supported the women to cope with their diabetes a total reliance on God resulted in disengagement with self-care. Shame associated with disclosure also prevented effective self-management. Finally, structural factors such as access to healthcare, poor health literacy and cultural barriers associated with obesogenic environments impeded women from seeking appropriate diabetes care. However, family and community were critical in ensuring women were supported with their diabetes self-management. The findings highlight the importance of engaging families in healthcare planning decisions in the development of culturally responsive models of diabetes support care for API women with type 2 diabetes.

Internalization of Appearance Ideals and Not Religiosity Indirectly Impacts the Relationship Between Acculturation and Disordered Eating Risk in South and Southeast Asian Women Living in the United States

Objective

Studies that examine disordered eating in samples of Asian individuals living in the United States frequently combine all individuals of Asian descent into a single group, which can obscure important differences between groups and their experiences of acculturation. The goal of the present study was to establish the relation of acculturation, internalization of appearance ideals, and religiosity as predicting body dissatisfaction and disordered eating in women of South and Southeast Asian (SSEA) descent.

Method

Women of SSEA descent (N = 112) aged 18-51 years (M = 23.10, SD = 6.4) completed a battery of questionnaires that inquire about these variables. A path analysis was conducted with acculturation serving as the independent (exogenous) variable, religiosity and internalization of the thin ideal as mediators, and body dissatisfaction and disordered eating as dependent (endogenous) variables.

Results

Direct paths from acculturation to both body dissatisfaction and disordered eating were not significant. Thin ideal internalization completely accounted for the path from acculturation to both endogenous variables; whereas, religiosity did not significantly account for any indirect effect.

Discussion

For SSEA women, internalization of appearance ideals is a potentially greater risk factor for disordered eating than acculturation or religiosity. As this was an atemporal mediation analysis, more work needs to be done exploring predictors of internalization in this population and how that may impact the development of disordered eating.

Children's longitudinal bodyweight in Australia: Influence of migrant mothers' long-term residency, attachment to, and level of childhood overweight in country-of-birth

Immigration creates opportunities and imposes constraints associated with acculturation. We used the Australian national longitudinal survey of children aged 2 to 17 to evaluate the influence of mothers' long-term residency in Australia, mothers' attachment to country-of-birth, and macro indicators of childhood overweight environment at mothers' country-of-birth on children's longitudinal bodyweight. Both mothers' long-term exposure to the Australian environment and attachment to country-of-birth were associated with increased children's bodyweight z-scores. The childhood overweight environment in mothers' country-of-birth continued to influence their children's bodyweight after immigration. A better understanding of factors related to mothers' migration and children's bodyweight status is necessary to identify risk factors and migrant sub-groups needing extra support.

The Lived Experiences of Fathers in Mealtimes: A Thematic Synthesis of Qualitative Literature

The paternal experience of family mealtimes is an emerging field within qualitative literature. Previous quantitative studies suggest that differences exist between fathers’ and mothers’ mealtime behaviours, particularly in response to fussy eating. However, qualitative research has not yet focused exclusively on fathers’ fussy eating experiences. This metasynthesis aimed to provide insights into the general paternal experience, inclusive of their fussy eating responses. Thematic synthesis methodology was adopted to achieve this process and consisted of a systematic search resulting in the inclusion of 16 studies (18 papers). The direct quotations presented within each study were subjected to three stages of analysis to produce three analytical themes, supported by eight descriptive themes. The analytical themes presented were: (1) environmental influences on fathers’ mealtime experiences; (2) attitudes and emotions of fathers during mealtimes; and (3) observable behaviours of fathers during mealtimes. These themes highlighted the complexity of the mealtime experience from a paternal perspective. Multidirectional relationships were identified between each mealtime component (i.e., the environment, attitudes, emotions and behaviours) as evidenced by the paternal commentary presented. The findings also provided insights into fathers’ fussy eating experiences, recognising that fathers should be considered as individuals in the presence of mealtime intervention.

Exploring the Determinants of Food Choice in Chinese Mainlanders and Chinese Immigrants: A Systematic Review

Determinants of food choice in Chinese populations have not been systematically synthesised using a cultural lens. This study reviewed qualitative studies exploring food choice determinants of both Chinese mainlanders and Chinese immigrants living in Western countries. Ovid Medline, CINAHL Plus, Web of Science, ProQuest, and China National Knowledge Infrastructure database (CNKI) were searched from database inception to 1 April 2021. Studies were included if they involved qualitative research methods, were written in English or Chinese, investigated the factors influencing food choices, and targeted Chinese mainlanders or Chinese immigrants living in Western countries. Twenty-five studies (24 in English, 1 in Chinese) were included, involving 2048 participants. Four themes were identified; (1) the principles of traditional Chinese medicine (TCM), (2) perceptions of a healthy diet in Chinese culture (e.g., regular eating, eating in moderation, and emphasis on food freshness), (3) the desire to maintain harmony in families/communities, and (4) physical/social environmental factors all significantly influenced Chinese people's food choices. It is important to acknowledge these factors when developing culturally appropriate nutrition programs for promoting health in Chinese mainlanders and Chinese immigrants.

Diet quality during the COVID-19 pandemic: Effects of workplace support for families and work-to-family enrichment in dual-earner parents with adolescent children

Organizational support goes beyond the work domain, supporting workers' family role and thus generating resources that lead to work-to-family enrichment. Workers may invest these resources in improving their, and their family's, diet quality. However, data on the link between work resources, enrichment and diet quality during the COVID-19 pandemic is still emerging. The present study contributes to this literature by exploring the actor and partner effects between perceived workplace support for families, work-to-family enrichment, and diet quality in different-sex dual-earner parents with adolescent children; the potential mediating role of work-to-family enrichment between perceived workplace support for families and diet quality was also explored. A sample of 430 different-sex dual-earner parents and one of their adolescent children (mean age 13.0 years, 53.7% female) were recruited in Rancagua, Chile, during March and June 2020. Mothers and fathers responded to a measure of work-to-family enrichment, and a measure of Perceived Workplace Support for Families. The three family members answered the Adapted Healthy Eating Index. Analyses were conducted using the Actor-Partner Interdependence Model and structural equation modelling. Results showed that fathers' perceived workplace support for families positively and directly affected their own diet quality (actor effect) as well as the mothers' diet quality (partner effect), while indirectly positively affected the adolescents' diet quality via work-to-family enrichment (partner effect). Mothers' perceived workplace support for families enhanced their own work-to-family enrichment, which in turn improved their diet quality (actor effects). These results suggest that resources that both parents acquire through family-friendly workplace policies have positive effects on the three family members' diet quality by different mechanisms. Policymakers and organizations must aim to promote family-friendly workplace policies, particularly during ongoing crisis such as a pandemic.

Eating styles profiles in Chilean women: A latent Profile analysis

The aims of this study were to identify profiles of women based on their levels of emotional, external and restraint eating, and to determine differences in these eating styles profiles based on nutritional status, sociodemographic characteristics, stress, social support, and satisfaction with the body image. Questionnaires were administered to 884 women aged 20 to 60 living in two Chilean cities. Questionnaires included the Dutch Eating Behavior Questionnaire (DEBQ), the Medical Outcomes Study-Social Support Survey, and the Perceived Stress Scale (PSS). Satisfaction with body image was assessed using a body-image-related single question. Nutritional status and sociodemographic characteristics were also assessed. Latent Profile Analysis (LPA) was used to identify profiles based on the three eating styles measured by the DEBQ. LPA allowed to distinguish four eating styles profiles: "women with medium emotional and external eating, high dietary restraint" (Profile 1, 36.64%); "women with low emotional, external and restraint eating" (Profile 2, 25.25%), "women with high emotional, external and restraint eating" (Profile 3, 21.85%); and "women with very low emotional and external eating, low dietary restraint" (Profile 4, 16.26%). Profile 1 had a greater proportion of women moderately satisfied with their body image. Profiles 2 and 4 scored higher in perceived social support and had greater proportions of women satisfied with their body image. Profile 4 had a higher proportion of married or cohabiting women. Profile 3 scored higher in the PSS and had higher proportion of obese and unsatisfied with their body image women. These results suggest that interventions to reduce emotional, external and restraint eating should not only involve the women, but also their family members.

An Interaction Path of Mothers' and Preschoolers' Food- and Physical Activity-Related Aspects in Disadvantaged Sicilian Urban Areas

Background: The relationship between mothers and their children’s lifestyle is still unclear, especially in disadvantaged areas. Consequently, the study aims to identify a path explaining the extent to which maternal eating habits and physical activity (PA) level predict food-related aspects, PA practice and Quotient of Gross Motor Development (QGMD) in preschoolers from disadvantaged urban areas. Methods: In this cross-sectional study, a total of 79 dyads of mothers and children were recruited from kindergartens. Information related to family socio-demographic aspects, mothers’ and children’s dietary intake frequencies and PA/sedentariness, mothers’ weight and height, mothers’ perception on children’s food intake, and children’s food literacy (FL) was collected with a questionnaire and the Food Literacy Assessment Tool (preschool-FLAT), while gross-motor skills were measured with the Test of Gross Motor Development (TGMD); weight and height of children were directly collected. Results: Associations were found between mothers’ and children’s food habits; mothers’ and children’s fruit/vegetables consumption, and intake of the other items; mothers’ education or PA level and children’s FL; mothers’ PA or sedentariness and children’s QGMD; mothers’ BMI and food habits and children’s BMI; education and food habits. Conclusions: These findings can be useful to plan effective interventions targeted both to preschoolers and their mothers of disadvantaged urban areas for promoting healthy lifestyles, which have become increasingly difficult to achieve during COVID-19 pandemic.

Determinants of Household Food Basket Composition: A Systematic Review

Background:

Demographic, socioeconomic, and environmental determinants are important to population health status in all countries and diet is the main way that these factors could affect health. We aimed to conduct a systematic review of recent research evidence about these determinants of household food basket composition.

Methods:

The PRISMA guideline was used to the reproducibility of this systematic review. Three databases including PubMed, Scopus and Google Scholar were systematically searched from 1991 to Dec 2017.

Results:

Thirty four studies were included. Most studies were done in the United States. Three categories of determinants including the demographic, socioeconomic, and environmental define the contribution of different food groups in the household food basket. These factors determine the healthiness of family diet.

Conclusion:

Many determinants affect household food basket. Comprehensive consideration of policymakers to these factors is essential to creating and maintaining a healthy society.

How do we improve adolescent diet and physical activity in India and sub-Saharan Africa? Findings from the Transforming Adolescent Lives through Nutrition (TALENT) consortium

OBJECTIVE

Adolescent diet, physical activity and nutritional status are generally known to be sub-optimal. This is an introduction to a special issue of papers devoted to exploring factors affecting diet and physical activity in adolescents, including food insecure and vulnerable groups.

SETTING

Eight settings including urban, peri-urban and rural across sites from five different low- and middle-income countries.

DESIGN

Focus groups with adolescents and caregivers carried out by trained researchers.

RESULTS

Our results show that adolescents, even in poor settings, know about healthy diet and lifestyles. They want to have energy, feel happy, look good and live longer, but their desire for autonomy, a need to 'belong' in their peer group, plus vulnerability to marketing exploiting their aspirations, leads them to make unhealthy choices. They describe significant gender, culture and context-specific barriers. For example, urban adolescents had easy access to energy dense, unhealthy foods bought outside the home, whereas junk foods were only beginning to permeate rural sites. Among adolescents in Indian sites, pressure to excel in exams meant that academic studies were squeezing out physical activity time.

CONCLUSIONS

Interventions to improve adolescents' diets and physical activity levels must therefore address structural and environmental issues and influences in their homes and schools, since it is clear that their food and activity choices are the product of an interacting complex of factors. In the next phase of work, the Transforming Adolescent Lives through Nutrition consortium will employ groups of adolescents, caregivers and local stakeholders in each site to develop interventions to improve adolescent nutritional status.

'I should be disease free, healthy and be happy in whatever I do': a cross-country analysis of drivers of adolescent diet and physical activity in different low- and middle-income contexts

OBJECTIVE

To explore perceptions of how context shapes adolescent diet and physical activity in eight low- and middle-income (LMIC) sites at different stages of societal and economic transition.

DESIGN

Novel qualitative secondary analysis of eight data sets generated as part of the international Transforming Adolescent Lives through Nutrition (TALENT) collaboration.

SETTING

Diverse sites in India and Sub-Saharan Africa.

PARTICIPANTS

Fifty-two focus group discussions with 491 participants (303 adolescents aged 10-17 years; 188 caregivers).

RESULTS

Analysis of pooled qualitative data identified three themes: (1) transitions in generational nutrition education and knowledge; (2) transition in caregiver-adolescent power balance and (3) the implications of societal and economic transition for diet and physical activity. Adolescents in urban and peri-urban areas could readily access 'junk' food. Diets in rural settings were determined by tradition, seasonality and affordability. Physical activity was inhibited by site-specific factors including lack of space and crime in urban settings, and the prioritisation of academic performance. Gender influenced physical activity across all sites, with girls afforded fewer opportunities.

CONCLUSIONS

Interventions to improve adolescent diet and physical activity in LMIC need to be complex, context-specific and responsive to transitions at the individual, economic and societal levels. Moreover, solutions need to acknowledge gender inequalities in different contexts, as well as structural and cultural influences on diet and physical activity in resource-limited settings. Programmes need to be effective in engaging and reconciling adolescents' and caregivers' perspectives. Consequently, there is a need for action at both the community-household level and also through policy.

Fathers' food parenting: A scoping review of the literature from 1990 to 2019

BACKGROUND

While food parenting is a robust area of inquiry, studies have largely focused on mothers. Given the diversity of family structures today and increases in fathers' engagement in caregiving, fathers' food parenting warrants attention.

OBJECTIVE

We present a scoping review of research on fathers' food parenting (1990-2019). Eligible studies included peer-reviewed research published in English documenting fathers' food parenting and presenting results for fathers separate from mothers.

RESULTS

Seventy-seven eligible studies were identified. Most studies were based in the U.S (63.6%) and utilized a cross-sectional design (93.5%). Approximately half of studies used a validated measure of food parenting (54.5%) and slightly less than 30% utilized theory (28.6%). Many studies did not report information on fathers' residential status (37.7%) or their relationship to the target child (biological vs social) (63.6%). Content analysis of study findings showed that: fathers are involved in food parenting, but at lower levels than mothers; there are few consistent mother-father differences in food parenting practices; and fathers' controlling food parenting is linked with negative nutrition outcomes in children while responsive food parenting is linked with positive child outcomes.

CONCLUSION

To better inform family interventions to prevent childhood obesity, future food parenting research with fathers should recognize the diversity of family structures and utilize prospective, theory-based, designs.

Mothers' Nutrition Knowledge Is Unlikely to Be Related to Adolescents' Habitual Nutrient Intake Inadequacy in Japan: A Cross-Sectional Study of Japanese Junior High School Students

Dietary habits in adolescence persist into adulthood; thus, it is important to identify the factors that influence adolescent diet and establish a healthy diet. This study aimed to examine the association between mothers' nutrition knowledge and their children's nutrient intake inadequacy among Japanese junior high school student-mother dyads. The participants were 288 students and their mothers. Data regarding mothers' nutrition knowledge were obtained using a validated, self-administered general nutrition knowledge questionnaire for Japanese adults (JGNKQ). Participants were categorised into two groups according to the mothers' total JGNKQ scores. Adolescents' dietary habits during the preceding month were assessed using a brief self-administered diet history questionnaire. Inadequacy of each nutrient intake was assessed using the cut-point method, which showed that 14 nutrients were below "estimated average requirement (EAR)" and five nutrients were outside the range of "tentative dietary goal to prevent lifestyle-related diseases (DG)". In the habitual daily nutrient intakes and the proportion of nutrient intake inadequacy of the students, no differences were observed according to mother's nutritional knowledge level. Our findings suggest that mothers' nutrition knowledge may not be directly associated with adolescents' nutrient intake among Japanese junior high school student-mother dyads.

Finding my own way in the kitchen from maternal influence and beyond - A grounded theory study based on Brazilian women's life stories

Mothers are frequently seen as the gatekeepers of the transmission of food-related meanings and practices to their children, but little is known about how they transmit cooking-related aspects. This study aimed to understand the intergenerational transmission of cooking-related meanings and practices using a life course perspective and a constructivist grounded theory approach to present a substantive theory. The study was carried out in southern Brazil with 27 women. The core category Finding my own way in the kitchen from maternal influence and beyond is explained by four other categories. The first three show (1) that daughters implicitly and explicitly learn the idea of cooking responsibility from their mothers; (2) that mothers influence daughters by the way they involve children in the kitchen and by the feelings they express regarding cooking and (3) that daughters learn cooking practices observing their mother's cooking, cooking together, receiving instructions and eating their mother's food. The fourth category shows that daughters recreate what they learned from the mother according to their own life trajectories, social and historical context, and the people they interact with. Some of what they recreate is now part of their mothers' lives, resulting in a bidirectional influence. Strategies designed to encourage cooking need to challenge the view that the activity is solely a woman's responsibility, as well as communicate to the parents that their influence goes beyond transmitting cooking practices, as the attitudes and feelings they express towards cooking are also transferred.

Improving the Reporting of Young Children's Food Intake: Insights from a Cognitive Interviewing Study with Mothers of 3-7-Year Old Children

Short food questions (SFQ) allow for rapid reporting of food intake across a variety of settings but are limited by poor validity and reliability. Understanding the recall process used by parents to report children’s food intake can improve question design and psychometric performance. This study aimed to improve understanding of how parents report children’s dietary intake using SFQ. Semi-structured, cognitive interviews were conducted with 21 mothers of 3–7-year-old children. Mothers were asked to ‘think-aloud’ while answering SFQ about their child’s food intake. Thematic analysis identified themes relating to parent’s question and answer process and barriers to recall. Information retrieval strategies focused on ‘use-of-time’ and ‘sphere of food provision’ and differed for core versus unhealthy foods. Recall of routine and home food provision were used to report core food intake, whereas recall of special occasions and food provision outside the home guided recall of discretionary foods. Mothers utilize different recall strategies for core and discretionary foods based on use of time and the sphere of food provision. The ease of reporting children’s dietary intake may be improved by utilizing a shorter recall time frame, clear and direct question wording, and use of food examples and recall prompts.

Food cultures and aging: a qualitative study of grandparents' food perceptions and influence of food choice on younger generations

OBJECTIVE

To explore food perceptions among grandparents and understand the influence of these perceptions on food choice for the younger generations in their family.

DESIGN

Qualitative methodology, thematic analysis of the transcripts from fourteen focus groups.

SETTING

Grandparents in the southern region of the United States.

SUBJECTS

Participants were fifty-eight Black, Hispanic, and White grandparents, predominantly women (72%), ranging in age from 44-86 years (mean age = 65·4 (sd 9·97) years).

RESULTS

Grandparents' perceptions related to personal food choice were related to health issues and the media. Grandparents' perceived influence on their children's and grandchildren's food choices was described through the themes of proximity and power (level of influence based on an interaction of geographic proximity to grandchildren and the power given to them by their children and grandchildren to make food decisions), healthy v. unhealthy spoiling, cultural food tradition, and reciprocal exchange of knowledge.

CONCLUSION

Our results highlight areas for future research including nutrition interventions for older adults as well as factors that may be helpful to consider when engaging grandparents concerning food decisions for younger generations to promote health. Specifically, power should be assessed as part of a holistic approach to addressing dietary influence, the term 'healthy spoiling' can be used to reframe notions of traditional spoiling, and the role of cultural food tradition should be adapted differently by race.

How do grandparents influence child health and development? A systematic review

Grandparents are often a key source of care provision for their grandchildren, yet they are sidelined in caregiving research and policy decisions. We conducted a global, systematic review of the literature to examine the scope and quality of studies to date (PROSPERO database CRD42019133894). We screened 12,699 abstracts across 7 databases, and identified 206 studies that examined how grandparents influence child health and development. Indicators of grandparent involvement were contact, caregiving behaviors, and financial support. Our review focused on two research questions: how do grandparents influence child health and development outcomes, and what range of child outcomes is reported globally? We examined study design, sample characteristics, key findings, and outcomes pertaining to grandchildren's physical health, socio-emotional and behavioral health, and cognitive and educational development.  Our search captured studies featuring grandparent custodial care (n = 35), multigenerational care (n = 154), and both types of care (n = 17). We found substantial heterogeneity in the data provided on co-residence, caregiving roles, resources invested, outcomes, and mechanisms through which "grandparent effects" are manifested. We identified two important issues, related to operationalizing indicators of grandparent involvement and conceptualizing potential mechanisms, leading to gaps in the evidence base. Currently, our understanding of the pathways through which grandparents exert their influence is constrained by limited data on what grandparents actually do and insufficient attention given to interpersonal and structural contexts. We present a conceptual framework to explicitly measure and theorize pathways of care, with a view to inform research design and policy implementation. We underscore the need for more robust data on three indicators of caregiver involvement-contact, behavior, and support-and for careful description of structural and interpersonal contexts in caregiving research.

Exploring Grandparents' Roles in Young Children's Lifestyle Behaviors and the Prevention of Childhood Obesity: An Australian Perspective

Childhood obesity remains a significant public health issue. Because lifestyle behaviors and weight are established early and track through life stages, prevention strategies must commence in the first years of life. Traditionally, such strategies target parents or formal child care providers. Yet grandparents are increasingly providing care to grandchildren and therefore have an important role in their eating and activity behaviors, which creates a major research gap. This commentary piece, focusing on the Australian context, argues that it is imperative and timely for obesity prevention research to include investigations regarding the role of grandparents in the prevention of obesity-related behaviors in young children.

Associations Between Maternal Nutrition Knowledge, Attitude, and Practice and 25-Hydroxyvitamin D Levels and Rickets in Children in Xinjiang Province, People's Republic of China

We explored the association between maternal nutrition knowledge, attitude, and practice (KAP) and 25-hydroxyvitamin D (25(OH)D) values in children with rickets in Xinjiang, People's Republic of China. We recruited 514 mothers with children (<2 years) from pediatric outpatient departments. We determined general status of families, maternal nutrition KAP, and 25(OH)D values in 212 children with rickets, with doctors using "Prevention and Treatment Program for Infant and Young Children Rickets" and "Application Guideline for Vitamin D and Bone Health in Adult Chinese (2014 Standard Edition)" to identify. We then assessed the associations between nutrition KAP and 25(OH)D values. The 25(OH)D values were positively correlated with maternal nutrition KAP scores. Factors influencing rickets included per-capita monthly dietary expenditure and spousal education level. Factors associated with nutrition practice included maternal education level, gestational vitamin D level, and nutrition knowledge. Augmented maternal nutrition KAP may improve 25(OH)D levels in children with rickets to a normal range.

The presence of children in households was associated with dietary intake among Japanese married women: the POTATO study

A growing body of evidence from Western countries shows that the presence of children in households is associated with the dietary intake of adults, but little is known about this relationship in non-Western countries with different food cultures. Our aim was to examine whether dietary intake was different with respect to the presence of young children in the home among Japanese married women. Subjects were Japanese married women (aged 23–44 years) living with children aged less than 5 years (n 73) and married women who did not have children (n 85). Data regarding habitual dietary intake were obtained using a validated, self-administered diet history questionnaire. A cross-sectional comparison between women with young children and women without children was conducted using ANCOVA adjusted for potential confounding factors. Women with young children had a significantly greater intake of protein, carbohydrates, Na, Zn and Cu than did women without children. Intake of cereals, pulses and sugar was significantly higher among mothers than among non-mothers. Intake of both alcoholic and non-alcoholic beverages was significantly higher among non-mothers than among mothers. Thus, the presence of young children at home might influence women's intake of macronutrients and some minerals, especially Na, and beverages among Japanese married women. Our findings suggest that effective dietary interventions among Japanese mothers with young children may differ from those of married women without children.

Somali, Latino and Hmong parents' perceptions and approaches about raising healthy-weight children: a community-based participatory research study

OBJECTIVE

Immigrants in the USA are confronted with health disparities, including childhood obesity and obesity-related chronic diseases. We aimed to identify perceptions of childhood body weight, approaches to raising healthy children and desires for supportive programmes of Somali, Latino and Hmong (SLM) parents in the Twin Cities, Minnesota, USA.

DESIGN

Using community-based participatory research, ten focus groups (FG) were conducted with sixty-seven parents (n 28 Somali, three FG; n 19 Latino, four FG; n 20 Hmong, three FG) of 3-12-year-old children in their native language. Demographic information was collected.

RESULTS

SLM parents perceived that health is not necessarily weight-based; childhood obesity is caused by overeating, eating unhealthy foods and sedentary activities; traditional foods are generally healthy while American foods are generally unhealthy; and healthy children are inherently physically active. Parents identified their goals as feeding children so they would be healthy and happy, helping them be active and safe, and teaching them to cook traditional foods to be self-sufficient and maintain their cultural identity. Parents were challenged by children's unhealthy food and sedentary preferences, their own uncertainties about healthy foods and behaviours, and structural factors. Parents thought interventions could help them with these challenges, including information about healthy foods, age-appropriate portion sizes, safe places to be active and strategies tailored to their cultural norms.

CONCLUSIONS

SLM parents are trying to raise healthy-weight children based on their understanding of children's health, weight, diet and physical activity, while dealing with social, economic and environmental challenges and trying to maintain cultural identity and traditions.

Diet Quality and Satisfaction with Life, Family Life, and Food-Related Life across Families: A Cross-Sectional Pilot Study with Mother-Father-Adolescent Triads

Family is a major determinant of children's and adolescents' eating behavior. The objectives of the present study were to assess diet quality, eating habits, satisfaction with life, family life, and food-related life in mother-father-adolescent triads, and to identify profiles of families according to family members' diet quality. Questionnaires were administered to a sample of 300 two-parent families with one child over the age of 10 in the city of Temuco (Chile), including the Adapted Healthy Eating Index (AHEI), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFoL) scale, Satisfaction with Family Life (SWFaL) scales, and questions relating to their eating habits. Positive relationships were found between the diet quality of the family members, particularly between mothers and adolescents. Three family profiles with different diet qualities were identified: "families with an unhealthy diet" (39.3%), "families in which mothers and adolescents have healthy diets, but the fathers' diets require changes" (14.3%), and "families that require changes in their diet" (46.4%). These findings stress the key role of mothers in determining family diet quality and suggest a positive relationship between diet quality and satisfaction with life.
