Association Between Picky Eating, Weight Status, Vegetable, and Fruit Intake in Children and Adolescents: Systematic Review and Meta-Analysis.

Aim: Picky eating is a common appetitive trait reported among children and adolescents and may have detrimental effects on their weight, vegetable, and fruit intake, impacting health status. However, an updated systematic review of the literature and summary of effect estimates is required. This study aims to explore the association between picky eating with weight, vegetable and fruit intake, vegetable-only intake, and fruit-only intake. Methods: A systematic literature search of six electronic scientific databases and data extraction was performed between November 2022 and June 2023. Original articles that examined picky eating in association with weight, vegetable and/or fruit intake were included. PRISMA guidelines were followed and meta-analytical and meta-regression analyses were conducted to compute summary effect estimates and explore potential moderators. PROSPERO registration: CRD42022333043. Results: The systematic review included 59 studies of which 45 studies were included in the meta-analysis. Overall, the summarized effect estimates indicated that picky eating was inversely associated with weight [Cohen's dz: -0.27, 95% confidence interval (CI): -0.41 to -0.14, p < 0.0001]; vegetable and fruit intakes (Cohen's dz: -0.35, 95% CI: -0.45, -0.25, p < 0.0001); vegetable-only intake (Cohen's dz: -0.41, 95% CI: -0.56, -0.26, p < 0.0001), and fruit-only intake (Cohen's dz: -0.32, 95% CI: -0.45, -0.20, p < 0.0001). Picky eating was positively associated with underweight (Cohen's dz: 0.46, 95% CI: 0.20, 0.71 p = 0.0008). Conclusion: Although effect sizes were small, picky eating was inversely associated with weight, vegetable, and fruit intakes, and positively associated with underweight in children and adolescents aged birth to 17 years.

The knowledge, attitudes, and behaviours of pregnant women regarding seafood consumption during the antenatal period: a qualitative study.

BACKGROUND: Maternal nutrition impacts fetal growth and development. The Food Standards Australia New Zealand (FSANZ) guidelines recommend pregnant women consume 2-3 servings (224-336 g) of fish/seafood per week to support intake of long chain omega 3 fatty acids, given adequate consumption supports numerous health benefits including reduced risk of preterm and early preterm birth. Evidence indicates that pregnant women purposely lower their fish/seafood intake, largely due to fears of methylmercury exposure. The aim of this study was to explore pregnant women's knowledge, attitudes, and behaviours regarding their fish/seafood consumption during the antenatal period. METHODS: Semi-structured interviews were conducted between October 2018 and December 2020 among a purposive sample of 12 pregnant women from the Australian Capital Territory (ACT). The interviews were recorded, transcribed verbatim, and analysed using an interpretative phenomenological approach. Themes were developed on the women's lived experience related to fish/seafood knowledge, attitudes, and consumption behaviour. RESULTS: The most prominent finding was widespread non-adherence to fish/seafood consumption guidelines. This was largely owing to a lack of proactive health promotion related to the health benefits of fish/seafood throughout pregnancy, including the health promoting roles of long chain omega 3 fatty acids for fetal growth and development. Three themes were identified: nutrition knowledge; sources of health promotion; and barriers and enablers to fish/seafood consumption. CONCLUSIONS: To support adequate maternal consumption of fish/seafood throughout pregnancy, emphasis should be placed on the benefits of consuming this food group regularly. Additionally, pregnant women should receive education about the health promoting role of long chain omega 3 fatty acids. Dietitians are well placed to provide this information.

Exploration of Malaysian school-children's food preferences: what do we know?

BACKGROUND: Feeding practices exert a definite influence over children's experiences. This article aims to explore parental feeding practices and investigate the prediction domain of food preference from parent-child perspectives. METHODS: Two individual studies were conducted on Malay families with children aged 7-12 years. In Study 1, mothers (n = 17) participated in semi-structured focus group interviews on their knowledge of foods and feeding practices. In Study 2, parent-child pairs (n = 14) answered a 36-item, 5-point Likert scale Food Preference Questionnaire followed by virtual structured qualitative interviews. The interviews were digitally recorded, transcribed verbatim, back-translated and analysed according to the framework analysis technique. RESULTS: In Study 1, mothers perceived vegetables, chicken, fish and plain water as healthy foods and drinks while discretionary options were snacks, fast foods and carbonated drinks. The mothers defined healthy foods as foods handled safely with health benefits. They used 'healthy' cooking methods to prepare preferred foods and overtly controlled the child's access to discretionary food. In Study 2, the food groups reported by parent-child pair's report were consistent for the most preferred foods [snacks, median (interquartile range), parent: 4.5 (1.0) vs. child: 4.5 (0.0), p > 0.05] and least preferred food [legumes, parent: 2.0 (1.0) vs. child: 2.0 (1.0), p > 0.05]. Parents emphasized taste as the key determinant of food preference. CONCLUSION: These studies were the first to qualitatively explore parents' perceptions of foods affecting their feeding practices among the Malaysian community to highlight the cultural contribution. Key insights into children's food intake and factors influencing their food preferences were identified.

Association Between a Low-Carbohydrate Diet, Glycemic Control, and Quality of Life in Australian Adults Living With Type 1 Diabetes: A Pilot Study.

OBJECTIVE: To examine if there is an association between a low-carbohydrate diet (LCD), glycemic control, and quality of life (QoL) in Australian adults with type 1 diabetes. METHODS: This single-group, pre-post, mixed methods (quantitative and qualitative) study was conducted in an outpatient tertiary hospital. Eligible participants were those aged ≥18 years, with type 1 diabetes for ≥1 year, and using multiple daily insulin injections. Participants followed a 12-week individualized LCD (<100 g/d). Daily glucose levels were monitored using a continuous glucose monitor. Glycated hemoglobin (HbA1c) and QoL were measured preintervention and postintervention. A post-hoc exploratory regression analysis determined whether changes in carbohydrate intake was associated with changes in HbA1c and QoL. Qualitative data collected postintervention explored participants' perceptions relating to a LCD, glycemic control, and QoL. RESULTS: Participants (n = 22) completed the 12-week LCD intervention. An LCD provided a statistically, significant improvement in HbA1c 0.83% (95% CI 0.32%-1.33%), P = .003 but did not impact QoL: estimated change 1.14 units (95% CI: -5.34 to 7.61); P = .72. The post-hoc exploratory regression analysis showed that participants with poorer baseline glycemic control were more likely to respond to an LCD resulting in significant reductions in HbA1c. Participant perceptions relating to the study variables were mixed. CONCLUSIONS: An LCD (<100 g/d) is a potentially effective and safe strategy to improve glycemic control without negatively effecting QoL in Australian adults with type 1 diabetes.

Identification and Evaluation of Tools Utilised for Measuring Food Provision in Childcare Centres and Primary Schools: A Systematic Review.

BACKGROUND: Children aged 2-11 years spend significant hours per week in early childhood education and care (ECEC) and primary schools. Whilst considered important environments to influence children's food intake, there is heterogeneity in the tools utilised to assess food provision in these settings. This systematic review aimed to identify and evaluate tools used to measure food provision in ECEC and primary schools. METHODS: The Preferred Reporting Items for Systematic Reviews (PRISMA) was followed. Publications (2003-2020) that implemented, validated, or developed measurement tools to assess food provision within ECEC or primary schools were included. Two reviewers extracted and evaluated studies, cross checked by a third reviewer and verified by all authors. The Academy of Nutrition and Dietetics Quality Criteria Checklist (QCC) was used to critically appraise each study. RESULTS: Eighty-two studies were included in the review. Seven measurement tools were identified, namely, Menu review; Observation; Weighed food protocol; Questionnaire/survey; Digital photography; Quick menu audit; and Web-based menu assessment. An evidence-based evaluation was conducted for each tool. CONCLUSIONS: The weighed food protocol was found to be the most popular and accurate measurement tool to assess individual-level intake. Future research is recommended to develop and validate a tool to assess service-level food provision.

Evaluation of a specialist antenatal nutrition clinic for women with a body mass index ≥ 40kg/m2: A qualitative study.

OBJECTIVE: To explore the views of women who attended a specialist antenatal nutrition clinic that was specifically developed and piloted for pregnant women with a BMI ≥ 40 kg/m2. DESIGN: A phenomenological approach, using individual interviews, was employed. Discussions were audio recorded, transcribed verbatim and scrutinised using Interpretive Phenomenological Analysis. Themes were pinpointed and supported with direct quotes to demonstrate results. SETTING AND PARTICIPANTS: Eight women, with a BMI ≥ 40 kg/m2, receiving antenatal care at a tertiary hospital in south eastern Australia and who participated in a specialist antenatal nutrition service were interviewed. FINDINGS: Three main themes emerged: 1) Motivation to be Healthy; 2) Woman Centred Nutrition Care; 3) Conflicts, Confusion and Assumptions. KEY CONCLUSIONS: Pregnant women with a BMI ≥ 40kgm2 responded positively to incorporating dietitians in the antenatal care setting. The reinforcement and reassurance provided by the specialist dietetic team was highly valued. More effective communication regarding referrals, improved consistency in information provided by the entire antenatal service and continuity of dietetic support beyond birth would add value to future interventions.

Circulating 25-hydroxy-vitamin D and the risk of cardiovascular diseases. Systematic review and meta-analysis of prospective cohort studies.

AIMS: Circulating vitamin D is linked with the risk of cardiovascular disease (CVD). A meta-analysis has yet to explicitly explore correlation between vitamin D and the risk of CVD incidence and recurrent CVD. This meta-analysis examines the association between 25-hydroxy-vitamin D (25(OH)D) and the risk of CVD incidence (fatal, non-fatal, fatal and non-fatal combined events) and the risk of recurrent CVD (fatal, recurrent, and fatal and recurrent combined events). PROSPERO registration-CRD42021251483. DATA SYNTHESIS: A total of 79 studies (46 713 CVD cases in 1 397 831 participants) were included in the meta-analysis, of which 61 studies examined the risk of CVD incidence events, and 18 studies examined risk of recurrent CVD events. The risk of CVD incidence events (RR = 1.34, 95% CI: 1.26-1.43, p < 0.001) and recurrent CVD events (RR = 1.86, 95% CI: 1.46-2.36, p < 0.001) was higher in the lowest than the highest category of circulating 25(OH)D. Dose-response analysis reported a linear association for every 10 ng/ml increment of 25(OH)D and non-fatal CVD incidence events (RR = 0.94; 95% CI = 0.89-0.98, p = 0.005), lower fatal recurrent CVD events (RR = 0.45; 95% CI = 0.32-0.62, p < 0.001) and lower combined recurrent CVD events (RR = 0.80; 95% CI = 0.65-0.97, p = 0.023). A non-linear association was observed between higher 25(OH)D and lower fatal CVD incidence events (P-nonlinear<0.001), lower combined CVD incidence events (P-nonlinear = 0.001), and lower non-fatal recurrent CVD events (P-nonlinear = 0.044). CONCLUSIONS: The lowest category of circulating 25(OH)D was associated with a higher risk of CVD incidence events and recurrent CVD events.

Maternal body mass index and country of birth in relation to the adverse outcomes of large for gestational age and gestational diabetes mellitus in a retrospective cohort of Australian pregnant women.

BACKGROUND: The prevalence of gestational diabetes mellitus in Australia has been rising in line with the increased incidence of maternal overweight and obesity. Women with gestational diabetes mellitus, high body mass index or both are at an elevated risk of birthing a large for gestational age infant. The aim was to explore the relationship between country of birth, maternal body mass index with large for gestational age, and gestational diabetes mellitus. In addition to provide additional information for clinicians when making a risk assessment for large for gestational age babies. METHOD: A retrospective cohort study of 27,814 women residing in Australia but born in other countries, who gave birth to a singleton infant between 2008 and 2017 was undertaken. Logistic regression analysis was used to examine the association between the aforementioned variables. RESULTS: A significantly higher proportion of large for gestational age infants was born to overweight and obese women compared to those who were classified as underweight and healthy weight. Asian-born women residing in Australia, with a body mass index of ≥40 kg/m2, had an adjusted odds ratio of 9.926 (3.859-25.535) for birthing a large for gestational age infant. Conversely, Australian-born women with a body mass index of ≥40 kg/m2 had an adjusted odds ratio of 2.661 (2.256-3.139) for the same outcome. Women born in Australia were at high risk of birthing a large for gestational age infant in the presence of insulin-requiring gestational diabetes mellitus, but this risk was not significant for those with the diet-controlled type. Asian-born women did not present an elevated risk of birthing a large for gestational age infant, in either the diet controlled, or insulin requiring gestational diabetes mellitus groups. CONCLUSIONS: Women who are overweight or obese, and considering a pregnancy, are encouraged to seek culturally appropriate nutrition and weight management advice during the periconception period to reduce their risk of adverse outcomes.

Living with type 2 diabetes mellitus in the Kingdom of Tonga: a qualitative investigation of the barriers and enablers to lifestyle management.

BACKGROUND: Despite the increasing prevalence of Type 2 Diabetes Mellitus (T2DM) in the Kingdom of Tonga, little is known of non-communicable disease experiences among adults living in this location. This investigation aimed to explore the barriers and enablers to healthy lifestyle in a group of men and women living with T2DM residing in this Pacific Island nation. METHODS: This qualitative study consisted of three semi-structured focus groups (n = 16), conducted at the only Tongan Public Hospital located at Nuku'alofa, capital of Tonga (north coast of the island of Tongatapu). Discussions were audio-recorded, transcribed, cross-checked for consistency, and entered into a word processing document for analysis. Thematic analysis was employed to synthesise results. RESULTS: Four main themes were identified: (1) Knowledge and Support; (2) Fear and Motivation; 3) Physical and Psychological Environment; and (4) Faith and Culture. CONCLUSIONS: The qualitative findings from this study will assist the future development and information dissemination of culturally appropriate lifestyle-related for men and women living with T2DM in the Kingdom of Tonga. The need for collaboration between practitioners at the hospital, the church, family members, and local traditional healers is important if the lifestyle-related needs and wants of this group of people are to be met.

Taste Sensitivity and Taste Preference among Malay Children Aged 7 to 12 Years in Kuala Lumpur-A Pilot Study.

The taste and food preferences in children can affect their food intake and body weight. Bitter and sweet taste sensitivities were identified as primary taste contributors to children's preference for consuming various foods. This pilot study aimed to determine the taste sensitivity and preference for bitter and sweet tastes in a sample of Malaysian children. A case-control study was conducted among 15 pairs of Malay children aged 7 to 12 years. Seven solutions at different concentrations of 6-n-propylthiouracil and sucrose were prepared for testing bitterness and sweet sensitivity, respectively. The intensity of both bitter and sweet sensitivity was measured using a 100 mm Labelled Magnitude Scale (LMS), while the taste preference was rated using a 5-point Likert scale. The participants were better at identifying bitter than sweet taste (median score 6/7 vs. 4/7). No significant differences were detected for both tastes between normal-weight and overweight groups (bitter: 350 vs. 413, p = 0.273; sweet: 154 vs. 263, p = 0.068), as well as in Likert readings (bitter 9 vs. 8: p = 0.490; sweet 22 vs. 22: p = 0.677). In this sample of Malay children, the participants were more sensitive to bitterness than sweetness, yet presented similar taste sensitivity and preference irrespective of their weight status. Future studies using whole food samples are warranted to better characterize potential taste sensitivity and preference in children.

Association Between a Low Carbohydrate Diet, Quality of Life, and Glycemic Control in Australian Adults Living With Type 1 Diabetes: Protocol for a Mixed Methods Pilot Study.

BACKGROUND: Globally, the prevalence of type 1 diabetes mellitus (T1DM) is rising. In 2020, a total of 124,652 Australians had T1DM. Maintaining optimal glycemic control (hemoglobin A1c ≤7.0%, ≤53 mmol/mol) on a standard carbohydrate diet can be a challenge for people living with T1DM. The Diabetes Complications and Control Trial established that macrovascular and microvascular complications could be reduced by improving glycemic control. Recent studies have found that a very low or low carbohydrate diet can improve glycemic control. However, the overall evidence relating to an association between a very low or low carbohydrate diet and glycemic control in people living with T1DM is both limited and mixed. In addition, research has suggested that a reduced quality of life due to anxiety and depression adversely influences glycemic control. Despite a potential link between a very low or low carbohydrate diet and optimal glycemic control, to our knowledge, no research has examined an association between a low carbohydrate diet, quality of life, and glycemic control, making this study unique in its approach. OBJECTIVE: The study aims to develop a validated diabetes-specific quality of life questionnaire for use in Australian adults with T1DM and to determine if an association exists between a low carbohydrate diet, quality of life, and glycemic control in Australian adults living with T1DM. METHODS: This cross-sectional study will be conducted in a tertiary hospital outpatient setting and will consist of 3 phases: phase 1, online Australian diabetes-specific quality of life questionnaire development and piloting (25-30 adults with T1DM); phase 2, questionnaire validation (364 adults with T1DM); and phase 3, a 12-week dietary intervention to determine if an association exists between a low carbohydrate diet, quality of life, and glycemic control in adults with T1DM (16-23 adults with T1DM). The validation of the study-developed Australian diabetes-specific quality of life questionnaire, and changes in hemoglobin A1c and quality of life in adults with T1DM while undertaking a low carbohydrate diet over 12 weeks will be the primary outcomes of this study. RESULTS: Phase 1 of the study is currently open for recruitment and has recruited 12 participants to date. It is anticipated that the first results will be submitted for publication in November 2021. Presently, no results are available. CONCLUSIONS: This study is the first of its kind in that it will be the first to generate a new validated instrument, which could be used in evidence-based practice and research to understand the quality of life of Australian adults with T1DM. Second, the low carbohydrate dietary intervention outcomes could be used to inform clinicians about an alternative approach to assist T1DM adults in improving their quality of life and glycemic control. Finally, this study could warrant the development of an evidence-based low carbohydrate dietary guideline for adults living with T1DM with the potential to have a profound impact on this population.

The relationship between maternal pre-pregnancy body mass index and exclusive breastfeeding initiation: Findings from an Australian obstetric cohort.

BACKGROUND: To assess the type of infant nutrition at initiation of first feed in association with increasing maternal pre-pregnancy Body Mass Index in an Australian obstetric population. METHODS: A retrospective cohort study from 2008 to 2013 was undertaken. Body Mass Index was available for 12,347 women categorised into groups according to: underweight (≤18 kg/m2); normal weight (19-24 kg/m2); overweight (25-29 kg/m2); obese class I (30-34 kg/m2); obese class II (35-39/kg2) and obese class III (40+ kg/m2). Type and initiation of infant feeding is routinely recorded in the study hospital's birthing outcomes system. Six body mass index categories and mode of infant feeding were examined using logistic regression. Confounding factors that were controlled for included smoking status, parity, country of birth and maternal age. RESULTS: Within this cohort, 609 (4.93%) women were underweight, 6235 (50.50%) had a normal BMI, 3116 (25.24%) were overweight, 1314 (10.64%) were obese class I, 596 (4.83%) were obese class II and 477 (3.86%) were obese class III. In adjusted models', as BMI rose, women were significantly less likely to initiate exclusive breastfeeding and more likely to exclusively formula feed. Women with a BMI of 40+ kg/m2 had an AOR of 2.91(CI 1.94-4.25) for initiating exclusive formula at the time of their infant's first feed. CONCLUSIONS: Women who are overweight or obese are significantly less likely to initiate exclusive breastfeeding and more likely to give exclusive formula at the time of their newborn infants first feed. Effective breastfeeding interventions are required for these high-risk groups in the days leading up to and within the first hours after birth.

Challenges to Introducing Integrated Diabetes Care to an Inner-Regional Area in South Western Sydney, Australia.

INTRODUCTION: Diabetes care often requires collaboration between general practitioners, allied health professionals, nurses, and/or medical specialists. This study aimed to describe the establishment of an integrated diabetes prevention and care approach in an area with limited access to primary and secondary care, and the challenges faced in its initial development. DESCRIPTION: A qualitative research approach to identify challenges was taken. Data included meeting minutes, observational data and reports involving local clinical and non-clinical stakeholders from June 2016- December 2018 and were thematically analysed. DISCUSSION: Key challenges were low patient attendance in general practice, healthcare professional time, low participation at health promotion activities/peer support groups and diabetes education reflecting a low priority among people with and at risk of diabetes. Coordination between services remained a challenge. CONCLUSION: This study highlights the need to integrate new diabetes services with existing health activities in the community and the importance of allowing flexibility and regular contact with local healthcare professional and community to encourage their involvement. Regular meetings with the funders, internal and external stakeholders are key for sustainability and to adapt programmes to the local situation. Further work is needed to identify and implement strategies to overcome these challenges.

The Association Between Pre-Pregnancy Body Mass Index, Perinatal Depression and Maternal Vitamin D Status: Findings from an Australian Cohort Study.

PURPOSE: This study aimed to assess the relationship between early-pregnancy Body Mass Index (BMI), perinatal depression risk and maternal vitamin D status. PATIENTS AND METHODS: A retrospective cohort study from 2013 to 2017 was undertaken involving 16,528 birth events in the Australian Capital Territory. Multivariate binary logistic regression was conducted using the forced entry method. Mediation of the association between maternal early-pregnancy BMI and perinatal depression risk by vitamin D status was also tested. RESULTS: Adjusted logistic regression models found that high maternal early-pregnancy BMI was associated with increased risk of developing perinatal depression (AOR 1.421; 95% CI, 1.191, 1.696) as well as increased odds of being vitamin D deficient (AOR 1.950; 95% CI; 1.735, 2.191). In comparison to women with low perinatal depression risk, women with high perinatal depression risk had increased odds of being vitamin D deficient (AOR 1.321; 95% CI, 1.105, 1.579). Maternal early-pregnancy BMI was a weak significant predictor of perinatal depression risk after including vitamin D as a mediator, consistent with partial mediation, Path C: B=0.016 (95% CI 1.003, 1.030), p= 0.02. Path C´: B=0.014 (95% CI 1.001, 1.028), p= 0.04. CONCLUSION: In line with current Australian recommendations, women with high early-pregnancy BMI should be screened for both perinatal depression risk and vitamin D deficiency, with referral to relevant support services when indicated.

Associations between appetitive traits, dietary patterns and weight status of children attending the School Kids Intervention Program.

BACKGROUND: The nexus between appetitive traits, dietary patterns and weight status has predominantly been studied in a mixed sample (healthy weight, overweight and obese sample). AIM: This cross-sectional study examined associations between overweight/obese children's appetitive traits, dietary patterns and weight status. METHODS: We studied children (N = 58, body mass index z-score: 2.25±0.46), 4-12 years attending the School Kids Intervention Program. Children's appetitive traits and dietary patterns were measured with the Child Eating Behaviour Questionnaire and Children's Dietary Questionnaire, respectively. Children's height and weight were used to compute body mass index z-score; waist circumference was also measured and waist-to-height ratio was calculated. RESULTS: After controlling for children's age and gender, hierarchical linear regression analyses showed that lower scores for slowness in eating were associated with higher body mass index z-scores in children (ß = -0.31, p = 0.01). Higher scores for emotional overeating were associated with higher waist-to-height ratio in children (ß = 0.48, p = 0.01). Higher scores for fussiness were correlated with lower scores for fruits and vegetables (ß = -0.59, p < 0.001) and higher scores for non-core foods (ß = 0.26, p = 0.04). CONCLUSION: Results observed in the current sample of overweight and obese children are consistent with previous studies examining healthy-weight children. Slowness in eating may foster an obesity 'protective' effect, whereas emotional overeating may promote susceptibility to weight gain. Fussy eating may impair diet quality by lower consumption of vegetables and fruits and higher intake of non-core foods. This evidence will support dietitians to consider children's appetitive traits when providing dietary consultation to support obesity management among overweight/obese children.

The Environmental and Bitter Taste Endophenotype Determinants of Picky Eating in Australian School-Aged Children 7-12 years-A Cross-Sectional Pilot Study Protocol.

Caregivers' perceptions of children's pickiness are relatively scarce in relation to the five core food groups and their importance in providing a nutritionally balanced diet. Furthermore, there is no validated questionnaire that examines child-reported food preferences in an age-appropriate manner, and the use of terms such as a "picky eater" can be attributed to environmental and genetic factors. Despite potential links between children's food preferences and endophenotype bitter taste, associations between bitter taste sensitivity and picky eating is relatively unexplored. The proposed cross-sectional study aims to develop and validate a parent-reported core-food Picky Eating Questionnaire (PEQ) and child-reported Food Preference Questionnaire (C-FPQ) and simultaneously investigate environmental and phenotype determinants of picky eating. The study will be conducted in three stages: Phase 1, piloting PEQ and C-FPQ questionnaires (15-20 primary caregivers and their children aged 7-12 years); Phase 2 and 3, validating the revised questionnaires and evaluating the 6-n-propylthiouracil (PROP) bitter taste sensitivity to examine perception to bitter taste (369 primary caregivers and their children). Study findings will generate new validated tools (PEQ, C-FPQ) for use in evidence-based practice and research and explore picky eating as a behavioural issue via the potential genetic-phenotype basis of bitter taste sensitivity.

Availability and price of healthier food choices and association with obesity prevalence in New Zealand Maori.

BACKGROUND AND OBJECTIVES: Examine availability and price of healthier foods-vs-regular counterparts and their association with obesity. METHODS AND STUDY DESIGN: A cross-sectional survey of weight and height among Maori in 2 urban and 96 rural areas in the Waikato/Lakes Districts-NZ (year 2004-06) was undertaken. Concurrently, availability of 11 'healthier' food in fast-food-outlets was examined by location (urban vs rural) and median income (high-low). In supermarkets, five-specific 'regular' foods were scored against 'healthier' counterparts (white-vs-wholemeal bread, with-skin-vs-skinless chicken, regular-vs-trim meat, standard-vs-trim milk, sugarsweetened- beverages vs-water) for in-store availability and price according to the Nutrition Environment Measures Survey. RESULTS: Overall, 3,817 Maori (BMI: women: 32.9±7.8 kg/m2; men: 33.1±6.7 kg/m2) were included with 451 food-outlets in two urban-clusters and 698 food-outlets in 96 rural-clusters. Fast-foods: The availability of healthier food choices was higher for 8/11 items in rural and low-income areas than urban and high-income areas. Multivariate analysis considered location and income as cofactors. No association between number of fast-food-outlets/cluster and healthier foods/cluster with obesity prevalence (General/Maori BMI cutoffs) was observed. Supermarkets: Water was cheaper than sugar-sweetened-beverages and negatively associated with obesity prevalence (General r=-0.53, p=0.03; Maori r=-0.53, p=0.03); high availability scores for trim milk compared to standard milk correlated with higher obesity prevalence (General r=0.49, p=0.04; Maori r=0.57, p=0.01). CONCLUSIONS: Bottled water vs sugar-sweetened-beverages prices were inversely associated with obesity. This supports the argument to regulate the availability and price of sugar-sweetened-beverages in NZ. The positive association of the availability of trim milk with the prevalence of obesity warrants investigation into individual's dietary and food-purchase behaviour.

Protein intake and physical activity are associated with body composition in individuals with phenylalanine hydroxylase deficiency.

OBJECTIVE: Determine whether body composition as it relates to dietary protein in patients with phenylalanine hydroxylase (PAH) deficiency is associated with genotype, dietary factors, and lifestyle choices. METHODS: We examined associations between protein intake (intact and medical foods: MF) and body composition in PAH-deficient patients along with, physical activity, and genotype. Protein intakes (total, intact, and MF) were analysed from three-day food records with Nutrition Data System for Research (NDSR) in 59 children and 27 adults (N=86, median age=16.0years). The severity of PAH deficiency was classified using the genotype assigned value method (AV sum). Physical activity was assessed using a study-developed question (light vs. intense activity). Body composition was measured by DXA, including android:gynoid ratio (A:G), fat-free mass index (FFMI), fat mass index (FMI), and FMI:FFMI ratio. RESULTS: High intact protein intake was associated with high FFMI (rs=0.75, p=0.008) and low FMI:FFMI (rs=-0.59, p=0.04) in adults. Only in children, MF protein (rs=0.38, p=0.04) was directly proportional to FFMI. Median intact protein intakes of adults (25.1 vs. 9.9g/d, p<0.001) and children (11 vs. 6g/d, p<0.001) were higher than prescribed. Only in adults, the actual median MF protein intake was lower than prescribed (53 vs. 60g/d, p=0.03). In adults and children, light activity was associated with higher fat mass indices compared to intense activity (adults: FMI:FFMI: ß=1.1, p=0.001, children: FMI:FFMI: ß=1.1, p=0.007; FMI ß=2.1, p=0.01; A:G ß=1.1, p=0.04). All associations remained significant after covariate adjustment. Genotype was not associated with body composition. CONCLUSIONS: Although fat-free mass in adults was positively associated with intact protein intake, it should be consumed as prescribed per individual tolerance to maintain plasma Phe concentrations within treatment range. In children, total protein maximized with MF should be encouraged to promote lean mass. Nutrition counselling could be complemented with physical activity recommendations for optimal clinical outcomes.
