Maternal pre-pregnancy diet and prenatal depression: the mediating role of pre-pregnancy weight status and prenatal inflammation.

Depression is a common prenatal psychological complication. We aimed to investigate if maternal pre-pregnancy diet can impact prenatal depressive symptoms and the mediating role of pre-pregnancy BMI and inflammation. We used data (N 1141) from the Alberta Pregnancy Outcomes and Nutrition cohort study. We calculated Mediterranean diet adherence (MED) and dietary inflammatory index (DII) scores using data from pre-pregnancy FFQ. In the third-trimester, we assessed depressive symptoms using Edinburgh Postpartum Depression Scale (EPDS) and inflammation through serum C-reactive protein (CRP) levels. BMI was calculated from self-reported pre-pregnancy weight. Race-stratified analyses (white and people of colour) were run. We observed no association between MED or DII tertiles and depressive symptoms. However, white participants in the MED tertile-3 had lower risk of depression (EPDS < 10) compared with tertile-1 (OR = 0·56, 95 % CI, 0·33, 0·95). White individuals in MED tertile-3 had lower BMI (MD = -1·08; 95 % CI, -1·77, -0·39) and CRP (MD = -0·53; 95 % CI, -0·95, -0·11) than tertile-1, and those in DII tertile-2 (MD = 0·44; 95 % CI, 0·03, 0·84) and tertile-3 (MD = 0·42; 95 % CI, 0·01, 0·83) had higher CRP than tertile-1. Among people of colour, neither MED nor DII was associated with BMI or CRP, but BMI was negatively associated with depressive symptoms (ß = -0·25, 95 % CI, -0·43, -0·06). We found no association between diet and depressive symptoms through BMI or CRP, in either race. Pre-pregnancy diet might affect the risk of prenatal depression in a race-specific way. Further research is required to explore the racial differences in the association between maternal diet and prenatal depressive symptoms/depression risk.

Pre-Diagnosis Diet Predicts Response to Exclusive Enteral Nutrition and Correlates with Microbiome in Pediatric Crohn Disease.

Exclusive enteral nutrition (EEN) is effective in inducing remission in pediatric Crohn disease (CD). EEN alters the intestinal microbiome, but precise mechanisms are unknown. We hypothesized that pre-diagnosis diet establishes a baseline gut microbiome, which then mediates response to EEN. We analyzed prospectively recorded food frequency questionnaires (FFQs) for pre-diagnosis dietary patterns. Fecal microbiota were sequenced (16SrRNA) at baseline and through an 18-month follow-up period. Dietary patterns, Mediterranean diet adherence, and stool microbiota were associated with EEN treatment outcomes, disease flare, need for anti-tumor necrosis factor (TNF)-α therapy, and long-term clinical outcomes. Ninety-eight patients were included. Baseline disease severity and microbiota were associated with diet. Four dietary patterns were identified by FFQs; a "mature diet" high in fruits, vegetables, and fish was linked to increased baseline microbial diversity, which was associated with fewer disease flares (p < 0.05) and a trend towards a delayed need for anti-TNF therapy (p = 0.086). Baseline stool microbial taxa were increased (Blautia and Faecalibacterium) or decreased (Ruminococcus gnavus group) with the mature diet compared to other diets. Surprisingly, a "pre-packaged" dietary pattern (rich in processed foods) was associated with delayed flares in males (p < 0.05). Long-term pre-diagnosis diet was associated with outcomes of EEN therapy in pediatric CD; diet-microbiota and microbiota-outcome associations may mediate this relationship.

Maternal pre-pregnancy weight status and gestational weight gain in association with child behavior: The mediating role of prenatal systemic inflammation.

BACKGROUND AND AIMS: Maternal pre-pregnancy obesity and excessive gestational weight gain (EGWG) may predispose children to behavioral problems through increased prenatal inflammation. We investigated the association between maternal body mass index (BMI) and gestational weight gain (GWG), and child behavioral problems (primary aim), and the mediating role of prenatal inflammation (secondary aim). METHODS: We used self-reported pre-pregnancy BMI and estimated-GWG data (N = 1137) from a longitudinal cohort study. Maternal serum C-reactive protein (CRP) was measured in the 3rd-trimester. Parent-reported Child Behavior Checklist (CBCL) was used to assess child internalizing and externalizing behaviors at 3-years-of-age. We used analysis of covariance (ANCOVA), multiple linear regression, and mediation analyses for data analysis. RESULTS: Maternal obesity (F = 21.98, df 3836), EGWG (F = 6.53, df 2764), and their combination (F = 18.51, df 3764) were associated with the 3rd trimester CRP, but not child behavior in the whole sample. Maternal underweight was associated with withdrawal problems in all children (ß = 0.56, 95%CI, 0.11,1.00) and aggressive behaviors in female children (ß = 2.59, 95%CI, 0.28,4.91). Obesity had a significant association with externalizing behaviors in female children after controlling for maternal CRP (ß = 3.72, 95%CI, 0.12,7.32). Both inadequate and EGWG were associated with somatic complaints in male children (ß = 0.50, 95%CI, 0.05,0.95; ß = 0.36, 95%CI, 0.01,0.71, respectively). Combined obesity/EGWG was associated with externalizing (ß = 6.12, 95%CI, 0.53,11.70) and aggressive (ß = 4.23, 95%CI, 0.90,7.56) behaviors in female children. We found no significant effects through CRP. CONCLUSIONS: Maternal pre-pregnancy BMI and GWG showed sex-specific associations with child behavioral problems. Prenatal CRP, although increased in obesity and EGWG, did not mediate these associations.

Applying suggested new terminology and definitions for human milk feeding in the Alberta Pregnancy Outcomes and Nutrition (APrON) longitudinal pregnancy cohort.

The complexity of human milk-feeding behaviours may not be captured using simpler definitions of "exclusive" and "non-exclusive" breastfeeding. New definitions have been suggested to describe variation in these behaviours more fully but have not been widely applied. We applied the new definitions to data derived from 3-day human milk-feeding diaries. Participants (n = 1091) recorded the number, beginning/end time, and modes of feeding of infants aged 3 months. Data were used to create six exclusive groups according to feeding mode(s): (1) human milk at-breast only; (2) human milk at-breast and human milk in a bottle; (3) human milk at-breast and infant formula in a bottle; (4) human milk at-breast and human milk and infant formula mixed in the same bottle; (5) human milk at-breast, human milk in a bottle, and infant formula in a bottle (not mixed); and (6) a bottle that sometimes contained human milk and sometimes infant formula (not mixed), never at-breast. Differences in maternal and infant characteristics were examined among groups. Fifty-seven percent fed at-breast only (Group 1). Those in Group 1 spent a similar amount of time feeding directly at-breast (median 132 (IQR 98-172) min/day) as those in Groups 2 (124 (95-158)), 3 (143 (100-190)), and 5 (114 (84-142)) (p > 0.05), indicating that adding bottle feeding did not always reduce the time infants were fed at-breast. Applying new suggested definitions to describe human milk-feeding behaviours from the mothers' perspective highlights the complexity of patterns used and warrants further application and research to explore impacts on health outcomes.

The Role of Mealtimes in Fostering Language Development and Aligning Home and School Learning: Protocol for a Multi-Method Study of Preschool Children in Rural Kenya and Zambia.

BACKGROUND: The association between school and home is fundamental to sustainable education: parents' understanding of the school's priorities and teachers' understanding of their pupils' home environment are both vital for children to remain in school and succeed academically. The relationship between parents and teachers is closest in preschool settings, providing a valuable opportunity to build bridges between home and school. In this protocol paper, we outline our planned methods for identifying beneficial home and school behaviors. OBJECTIVE: Our project aims to identify culture-specific structures and behaviors in home and school settings, which influence the quantity and quality of child-directed speech and identify positive experiences that can help improve children's linguistic development and nutrition. METHODS: Using a mixed methods approach and focusing on early language learning, nutrition, and responsive caregiving, we will video-record and analyze mealtime language and eating behaviors at home and in school, targeting 80 preschool children and their families in rural Kenya and Zambia. In addition, we will assess children's language skills through audio recordings and use questionnaire-based interviews to collect extensive sociodemographic and dietary data. RESULTS: Between the start of our project in January 2020 and the end of December 2021, we had collected complete sets of sociodemographic, observational, and food recall data for 40 children in Kenya and 16 children in Zambia. By the end of May 2022, we had started data collection for an additional 24 children in Zambia and transcribed and coded approximately 85% of the data. By the end of September, 2022, we plan to complete data collection, transcription, and coding for the entire sample of 80 children across both countries. From September 2022 onwards, we will focus on analyzing our language data, and we hope to have results ready for publication in early 2023. By relating children's language outcomes and nutritional intake to the observed mealtime behaviors, we hope to identify practices that increase the quantity and quality of child-directed speech and improve children's nutritional intake. CONCLUSIONS: Good nutrition and the promotion of language learning are key issues in early childhood development. By using a cross-cultural approach, combining a variety of methods, and working closely with stakeholders and policy makers throughout the project, we hope to find and share best practices for improving children's linguistic outcomes and nutrition and lay the foundation for the development of practitioner networks and parent outreach programs.

Qualitative Accounts of School-Aged Children's Diets during the COVID-19 Pandemic in Rural, Central, Kenya.

The COVID-19 pandemic has caused disruption to food security in many countries, including Kenya. However, the impact of this on food provision to children at an individual level is unknown. This small study aimed to provide a qualitative snapshot of the diets of children during the COVID-19 pandemic. During completion of 24-h food recalls, with 15 families with children aged 5-8 years, caregivers were asked about changes they had made to foods given to their children due to the pandemic. Food recalls were analysed to assess nutrient intakes. Qualitative comments were thematically analysed. Most of the families reported making some changes to foods they provided to their children due to COVID-19. Reasons for these changes fell into three themes, inability to access foods (both due to formal restriction of movements and fear of leaving the house), poorer availability of foods, and financial constraints (both decreases in income and increases in food prices). The COVID-19 pandemic has affected some foods parents in rural Kenya can provide to their children.

An exploration of differences in infant feeding practices among women with and without diabetes in pregnancy: A mixed-methods study.

AIMS: (1) To determine the likelihood of full breastfeeding at 3 months postpartum in women with and without diabetes in pregnancy (DiP); (2) to explore the associations between diabetes management practices and infant feeding practices in those who had DiP and (3) to examine women's experiences of feeding their infants after having DiP. METHODS: The quantitative study used data from Alberta Pregnancy Outcomes and Nutrition (APrON) cohort study. Participants who had DiP (n = 62) were matched 1:3 to participants without DiP for pre-pregnancy BMI, parity, mode of delivery and pre-term birth. Infant feeding questionnaires, prospective breastfeeding diaries and medical chart data were analysed to determine likelihood of fully breastfeeding at 3 months postpartum. For the qualitative study, interviews were conducted with postpartum women who had DiP to explore the experiences of infant feeding. Interviews were thematically analysed, and the results were compared between women who were categorized as 'full breast feeders' or 'mixed feeders'. RESULTS: The odds of fully breastfeeding were 50% lower in women with DiP than women without DiP (OR: 0.50, 95% CI 0.25-0.99, p = 0.04). Qualitative interviews identified that although all women showed resilience in the face of infant feeding challenges, those who were fully breastfeeding reported seeking out external infant feeding supports, for example, classes or Doula's. Mixed Feeders perceived there was a lack of infant feeding information and support given to them prior to giving birth. CONCLUSION: Women with DiP may require additional prenatal and postnatal infant feeding support to be better prepared to overcome feeding challenges they may face.

Association between breastfeeding during infancy and white matter microstructure in early childhood.

INTRODUCTION: Associations between breastfeeding and brain development, in the context of child, perinatal, and sociodemographic variables, remain unclear. This study investigated whether exclusive breastfeeding for the first 6 months and total duration of breastfeeding were associated with brain white matter microstructure in young children. METHODS: This study included 85 typically developing children (42 males) born to 83 mothers that were predominantly white, highly educated, and in high income households. Children underwent their first diffusion tensor imaging scan between ages 2.34 and 6.97 years; some children returned multiple times, providing a total of 331 datasets. Feeding information was collected from mothers at 3, 6, and 12 months postpartum and at their child's scan to calculate breastfeeding status at 6 months (exclusive or not) as well as total duration of any breastfeeding. Linear regression was used to investigate associations between breastfeeding exclusivity/duration and fractional anisotropy (FA) for the whole brain and 10 individual white matter tracts. RESULTS: Breastfeeding exclusivity and duration were associated with global and regional white matter microstructure, even after controlling for perinatal and sociodemographic factors. Greater exclusivity was associated with higher FA in females and lower FA in males. CONCLUSIONS: These findings suggest white matter differences associated with breastfeeding that differ by sex. These may stem from different trajectories in white matter development between males and females in early childhood and suggest possible long-term white matter differences associated with breastfeeding.

Use of healthy conversation skills to promote healthy diets, physical activity and gestational weight gain: Results from a pilot randomised controlled trial.

OBJECTIVES: This study evaluated the use of Healthy Conversation Skills (a client-centered communication approach to behaviour change) in supporting women to achieve optimal gestational-weight-gain and health behaviours. METHODS: Seventy pregnant women were randomised to the control or intervention group. Study visits and phone calls were delivered by Registered Dietitians (RDs) to women in the intervention and control groups. The intervention RD was trained in Healthy Conversation Skills while the control RD was not. Diet, physical activity and gestational-weight-gain were assessed at baseline and again at follow-up in the intervention and control groups. RESULTS: Women in the intervention group improved their diet score between baseline and visit 2, while the control group did not. At 34 weeks, women in the control group reported being sedentary for longer than women in the intervention group. There were no differences in total gestational-weight-gain between the groups. CONCLUSIONS: Pregnant women who interacted with an RD using Healthy Conversation Skills reported positive outcomes in health behaviours. PRACTICE IMPLICATIONS: Healthy Conversation Skills shows promise as an approach to initiate, and maintain discussions promoting health behaviour change in pregnancy.

Development of a diet quality index to assess adherence to Canadian dietary recommendations in 3-year-old children.

OBJECTIVE: Little is known about the diet quality of preschool children in Canada. We adapted an established diet quality index for European preschool children to align with the Canadian context and applied the index to dietary data of 3-year-old children to assess patterns of diet quality. DESIGN: Our diet quality index (DQI-C) consists of four components that align with Canada's Food Guide (Vegetables and Fruit, Grain Products, Milk and Alternatives and Meat and Alternatives) and two components that account for less healthy intakes (Candy/Snacks, and Sugar-Sweetened Beverages (SSB)). The ratio between consumption v. recommended intakes is calculated for each component and summed to give a total score from 0 to 6. SETTING: Alberta, Canada. PARTICIPANTS: The DQI-C was applied to FFQ data from 1260 3-year-old children. RESULTS: Mean DQI-C was 3·69 (sd 0·6). Most children met recommendations for Vegetables and Fruit (73 %) and Meat and Alternatives (70 %); however, fewer met recommendations for Milk and Alternatives (38 %) and Grain Products (13 %). Children in the lowest quartile for DQI-C score consumed a mean of 82 g of Candy/Snacks and 193 g of SSB daily, whereas those in the highest quartile consumed 45 g/d and 17 g/d of Candy and Snacks and SSB, respectively. CONCLUSION: This DQI-C score is useful for ranking Canadian preschool children according to their overall diet quality. There is room for improvement for consumptions of Grain Products, Meat and Alternatives, Candy/Snacks and SSB, which could be a target for initiatives to improve diet quality of preschool children in Canada.

Healthy conversation skills as an intervention to support healthy gestational weight gain: Experience and perceptions from intervention deliverers and participants.

OBJECTIVE: In a pilot RCT we assessed training a dietitian in "Healthy Conversation Skills" (HCS) to support behavior change. This study describes the acceptability of the intervention from the participant and practitioner perspective. METHODS: Seventy pregnant women participated (intervention = 33; control = 37). The evaluation included: i)audio-recording sessions to assess use of HCS from the intervention dietitian; ii)semi-structured interview with the intervention dietitian to assess experiences of using HCS; iii)Quality of Prenatal Care Questionnaire and focus groups to assess participants' views of study experience. RESULTS: Intervention sessions involved conversations where the dietitian used HCS. The dietitian reflected on the simplicity of learning HCS in training but the challenges of embedding these new skills in practice and highlighted the need to review and reflect on practice as an ongoing process. Intervention participants were more satisfied with the study (p = 0.05) and more likely to agree that the dietitian took time to ask about things that were important to them (p = 0.04) than control participants. CONCLUSION: Use of HCS by practitioners is an acceptable way to support lifestyle changes in pregnancy. PRACTICE IMPLICATIONS: Use of HCS provide opportunities to support behaviour change. Review of and reflecting on practice may facilitate the application of new skills in practice.

Dietary Patterns Prior to Pregnancy and Associations with Pregnancy Complications.

Few studies have explored pre-pregnancy diet and its relationship with pregnancy outcomes. The objectives of this study were to: (1) derive pre-pregnancy dietary patterns for women enrolled in a prospective cohort in the province of Alberta, Canada; (2) describe associations between dietary patterns and socio-demographic characteristics; and (3) describe associations between dietary patterns and pregnancy complications. Upon enrolment into the Alberta Pregnancy Outcomes and Nutrition (APrON) study (median age of gestation, 17 weeks), women (n = 1545) completed a validated 142-item food frequency questionnaire recording food and beverages consumed "in the 12 months prior to pregnancy". Other assessments included pre-pregnancy body mass index (BMI), gestational weight gain, gestational hypertension, gestational diabetes, and socio-demographic characteristics. Dietary patterns were derived using principal components analysis. Scores were calculated to represent adherence with each dietary pattern retained. Four dietary patterns were retained, accounting for 22.9% of the variation in the overall diet. Dietary patterns were named the "healthy", "meat and refined carbohydrate", "beans, cheese and salad" or "tea and coffee" patterns. Higher "healthy" pattern scores prior to pregnancy were associated with lower odds of developing gestational hypertension during pregnancy (adjusted Odds Ratio (OR): 0.6, 95% Confidence Intervals (CI): 0.4, 0.9). Diet prior to pregnancy is an important target for interventions and may reduce the likelihood of developing complications such as gestational hypertension during pregnancy.

Translating Developmental Origins: Improving the Health of Women and Their Children Using a Sustainable Approach to Behaviour Change.

Theories of the developmental origins of health and disease imply that optimising the growth and development of babies is an essential route to improving the health of populations. A key factor in the growth of babies is the nutritional status of their mothers. Since women from more disadvantaged backgrounds have poorer quality diets and the worst pregnancy outcomes, they need to be a particular focus. The behavioural sciences have made a substantial contribution to the development of interventions to support dietary changes in disadvantaged women. Translation of such interventions into routine practice is an ideal that is rarely achieved, however. This paper illustrates how re-orientating health and social care services towards an empowerment approach to behaviour change might underpin a new developmental focus to improving long-term health, using learning from a community-based intervention to improve the diets and lifestyles of disadvantaged women. The Southampton Initiative for Health aimed to improve the diets and lifestyles of women of child-bearing age through training health and social care practitioners in skills to support behaviour change. Analysis illustrates the necessary steps in mounting such an intervention: building trust; matching agendas and changing culture. The Southampton Initiative for Health demonstrates that developing sustainable; workable interventions and effective community partnerships; requires commitment beginning long before intervention delivery but is key to the translation of developmental origins research into improvements in human health.

Southampton PRegnancy Intervention for the Next Generation (SPRING): protocol for a randomised controlled trial.

BACKGROUND: The nutritional status and health of mothers influence the growth and development of infants during pregnancy and postnatal life. Interventions that focus on improving the nutritional status and lifestyle of mothers have the potential to optimise the development of the fetus as well as improve the health of mothers themselves. Improving the diets of women of childbearing age is likely to require complex interventions that are delivered in a socially and culturally appropriate context. In this study we aim to test the efficacy of two interventions: behaviour change (Healthy Conversation Skills) and vitamin D supplementation, and to explore the efficacy of an intervention that combines both, in improving the diet quality and nutritional status of pregnant women. METHODS/DESIGN: Women attending the maternity hospital in Southampton are recruited at between 8 and 12 weeks gestation. They are randomised to one of four groups following a factorial design: Healthy Conversation Skills support plus vitamin D supplementation (1000 IU cholecalciferol) (n = 150); Healthy Conversation Skills support plus placebo (n = 150); usual care plus vitamin D supplementation (n = 150); usual care plus placebo (n = 150). Questionnaire data include parity, sunlight exposure, diet assessment allowing assessment of diet quality, cigarette and alcohol consumption, well-being, self-efficacy and food involvement. At 19 and 34 weeks maternal anthropometry is assessed and blood samples taken to measure 25(OH) vitamin D. Maternal diet quality and 25(OH) vitamin D are the primary outcomes. Secondary outcomes are women's level of self-efficacy at 34 weeks, pregnancy weight gain, women's self-efficacy and breastfeeding status at one month after birth and neonatal bone mineral content, assessed by DXA within the first 14 days after birth. DISCUSSION: This trial is evaluating two approaches to improving maternal diet: a behaviour change intervention and vitamin D supplementation. The factorial design of this trial has the advantage of enabling each intervention to be tested separately as well as allowing exploration of the synergistic effect of both interventions on women's diets and vitamin D levels. TRIAL REGISTRATION: ISRCTN07227232 . Registered on 13 September 2013.

Patterns and trajectories of gestational weight gain: a prospective cohort study.

BACKGROUND: Gestational weight gain in excess of or below Health Canada's guidelines is known to increase the risk of adverse outcomes for both the woman and her baby. This study describes patterns and trajectories of total and rate of gestational weight gain in a large prospective cohort of pregnant women and adolescents in the Alberta Pregnancy Outcomes and Nutrition study. METHODS: We collected weight and height data for 1541 pregnant adolescents and women (mean age 31 years, < 27 weeks' gestation) recruited through advertisements and physicians' offices in Calgary and Edmonton between May 2009 and November 2012. Data were collected once during each trimester following enrolment and once at about 3 months post partum. The participants were categorized according to their prepregnancy body mass index (BMI) as underweight, of normal weight, overweight or obese. We calculated distributions of total and weekly rates of weight gain and determined trajectories of weight gain for each prepregnancy BMI category. RESULTS: Of the 1541 participants, 761 (49.4%) exceeded Health Canada's guidelines for total gestational weight gain, and 272 (17.6%) gained less weight than recommended. A total of 63 (19.2%) and 38 (23.6%) participants categorized as overweight or obese, respectively, exceeded the recommended upper limit by 5 to less than 10 kg, and 53 (16.2%) and 27 (16.8%), respectively, exceeded the upper limit by at least 10 kg. Ninety-five participants (30.3%) in the overweight group and 59 (39.6%) of those in the obese group gained weight at more than double the recommended rate between the second and third trimesters. The median weight gain for participants in the normal, overweight and obese categories had exceeded recommended upper limits by about 30, 20 and 18 weeks' gestation, respectively. INTERPRETATION: Adherence to Health Canada's guidelines for gestational weight gain was low. Excess gestational weight gain was most marked among those with a prepregnancy BMI in the overweight or obese category. The findings suggest that weight management in pregnancy is challenging and complex. Messages and supports that are tailored for women in different prepregnancy BMI categories may help to improve guideline-concordant gestational weight gain.

'Making every contact count': Evaluation of the impact of an intervention to train health and social care practitioners in skills to support health behaviour change.

A total of 148 health and social care practitioners were trained in skills to support behaviour change: creating opportunities to discuss health behaviours, using open discovery questions, listening, reflecting and goal-setting. At three time points post-training, use of the skills was evaluated and compared with use of skills by untrained practitioners. Trained practitioners demonstrated significantly greater use of these client-centred skills to support behaviour change compared to their untrained peers up to 1 year post-training. Because it uses existing services to deliver support for behaviour change, this training intervention has the potential to improve public health at relatively low cost.

How do mothers manage their preschool children's eating habits and does this change as children grow older? A longitudinal analysis.

The practices mothers adopt in relation to feeding their children have been identified as important predictors of children's quality of diet. However, most studies of the impact of these practices on quality of children's diets have been cross-sectional in design, limiting conclusions about change and causality. Previous research has called for qualitative exploration of the way these practices are used in a real-life setting. This study set out to address these gaps in knowledge. At baseline, mothers recruited to a community-based intervention study and who had a preschool child, completed a questionnaire about their use of covert and overt control practices, child food neophobia and demographics. The quality of children's diets was assessed using a validated food frequency questionnaire. Both questionnaires were repeated with the mothers two years later. Complete data at both time points were available for 228 mother-child pairs. Four focus group discussions were conducted with 29 mothers of preschool children to explore their experiences of feeding young children. Mothers who increased their use of overt control had children whose level of food neophobia also increased (P = 0.02). Mothers who used more covert control had children with better quality diets at both time points (P = <0.01) and mothers who increased their use of covert control over the two year follow-up had children whose diet quality improved (P = 0.003). These associations were independent of confounders such as mother's level of education. In the focus groups, mothers suggested that feeding young children was stressful and that control was often relinquished in order to reduce conflict at mealtimes. Supporting parents to adopt more covert techniques to control their children's eating habits may be an effective way of improving the quality of young children's diets.

Influences on the diet quality of pre-school children: importance of maternal psychological characteristics.

OBJECTIVE: To test the hypothesis that maternal psychological profiles relate to children's quality of diet. DESIGN: Cross-sectional study. Mothers provided information on their health-related psychological factors and aspects of their child's mealtime environment. Children's diet quality was assessed using an FFQ from which weekly intakes of foods and a diet Z-score were calculated. A high score described children with a better quality diet. Cluster analysis was performed to assess grouping of mothers based on psychological factors. Mealtime characteristics, describing how often children ate while sitting at a table or in front of the television, their frequency of takeaway food consumption, maternal covert control and food security, and children's quality of diet were examined, according to mothers' cluster membership. SUBJECTS: Mother-child pairs (n 324) in the Southampton Initiative for Health. Children were aged 2-5 years. SETTING: Hampshire, UK. RESULTS: Two main clusters were identified. Mothers in cluster 1 had significantly higher scores for all psychological factors than mothers in cluster 2 (all P < 0.001). Clusters were termed 'more resilient' and 'less resilient', respectively. Children of mothers in the less resilient cluster ate meals sitting at a table less often (P = 0.03) and watched more television (P = 0.01). These children had significantly poorer-quality diets (ß = -0.61, 95% CI -0.82, -0.40, P ≤ 0.001). This association was attenuated, but remained significant after controlling for confounding factors that included maternal education and home/mealtime characteristics (P = 0.006). CONCLUSIONS: The study suggests that mothers should be offered psychological support as part of interventions to improve children's quality of diet.

The effect of a behaviour change intervention on the diets and physical activity levels of women attending Sure Start Children's Centres: results from a complex public health intervention.

OBJECTIVES: The UK government's response to the obesity epidemic calls for action in communities to improve people's health behaviour. This study evaluated the effects of a community intervention on dietary quality and levels of physical activity of women from disadvantaged backgrounds. DESIGN: Non-randomised controlled evaluation of a complex public health intervention. PARTICIPANTS: 527 women attending Sure Start Children's Centres (SSCC) in Southampton (intervention) and 495 women attending SSCCs in Gosport and Havant (control). INTERVENTION: Training SSCC staff in behaviour change skills that would empower women to change their health behaviours. OUTCOMES: Main outcomes dietary quality and physical activity. Intermediate outcomes self-efficacy and sense of control. RESULTS: 1-year post-training, intervention staff used skills to support behaviour change significantly more than control staff. There were statistically significant reductions of 0.1 SD in the dietary quality of all women between baseline and follow-up and reductions in self-efficacy and sense of control. The decline in self-efficacy and control was significantly smaller in women in the intervention group than in women in the control group (adjusted differences in self-efficacy and control, respectively, 0.26 (95% CI 0.001 to 0.50) and 0.35 (0.05 to 0.65)). A lower decline in control was associated with higher levels of exposure in women in the intervention group. There was a statistically significant improvement in physical activity in the intervention group, with 22.9% of women reporting the highest level of physical activity compared with 12.4% at baseline, and a smaller improvement in the control group. The difference in change in physical activity level between the groups was not statistically significant (adjusted difference 1.02 (0.74 to 1.41)). CONCLUSIONS: While the intervention did not improve women's diets and physical activity levels, it had a protective effect on intermediate factors-control and self-efficacy-suggesting that a more prolonged exposure to the intervention might improve health behaviour. Further evaluation in a more controlled setting is justified.

Assessing diets of 3-year-old children: evaluation of an FFQ.

OBJECTIVE: To evaluate the use of an administered eighty-item FFQ to assess nutrient intake and diet quality in 3-year-old children. DESIGN: Frequency of consumption and portion size of the foods listed on the FFQ during the 3 months preceding the interview were reported by the child's main caregiver; after the interview a 2 d prospective food diary (FD) was completed on behalf of the child. Nutrient intakes from the FFQ and FD were estimated using UK food composition data. Diet quality was assessed from the FFQ and FD according to the child's scores for a principal component analysis-defined dietary pattern ('prudent' pattern), characterised by high consumption of fruit, vegetables, water and wholemeal cereals. SETTING: Southampton, UK. SUBJECTS: Children (n 892) aged 3 years in the Southampton Women's Survey. RESULTS: Intakes of all nutrients assessed by the FFQ were higher than FD estimates, but there was reasonable agreement in terms of ranking of children (range of Spearman rank correlations for energy-adjusted nutrient intakes, r s = 0·41 to 0·59). Prudent diet scores estimated from the FFQ and FD were highly correlated (r = 0·72). Some family and child characteristics appeared to influence the ability of the FFQ to rank children, most notably the number of child's meals eaten away from home. CONCLUSIONS: The FFQ provides useful information to allow ranking of children at this age with respect to nutrient intake and quality of diet, but may overestimate absolute intakes. Dietary studies of young children need to consider family and child characteristics that may impact on reporting error associated with an FFQ.
