Background Vitamin D may modify iron status through regulation of hepcidin and inflammatory pathways. This study aimed to investigate effects of maternal vitamin D supplementation on iron status in pregnancy and early infancy. Methods In a trial in Dhaka, Bangladesh, women (n=1300) were randomised to one of five vitamin D 3 regimens from 17 to 24 weeks’ gestation until 26 weeks postpartum (prenatal; postpartum doses): 0;0, 4200;0, 16 800;0, 28 000;0 or 28 000;28 000 IU/week. All participants received standard iron-folic acid supplementation. In this secondary analysis (n=998), we examined effects of prenatal;postpartum vitamin D on serum ferritin and other biomarkers of maternal iron status (transferrin saturation, total iron binding capacity, soluble transferrin receptor and hepcidin) at delivery, and infant ferritin and haemoglobin at 6 months of age. Using linear regression, we estimated per cent mean differences between each intervention group and placebo with 95% CIs, with and without adjustment for baseline ferritin or inflammatory biomarkers (C reactive protein and α-1-acid glycoprotein (AGP)). Results At delivery, ferritin concentrations were similar between each intervention group and placebo in unadjusted (n=998) and baseline ferritin-adjusted analyses (n=992; p>0.05). Compared with placebo, AGP was lower in each intervention group (per cent difference (95% CI) = −11% (−21 to –1.0), −14% (−23 to –3.5) and −11% (−19 to –2.0) in the 4200 IU/week, 16 800 IU/week and 28 000 IU/week groups, respectively; n=779). In the subgroup of women with baseline 25-hydroxyvitamin D < 30 nmol/L, ferritin was lower in each intervention group versus placebo (−23% (−37 to –5.0), −20% (−35 to –1.9) and −20% (−33 to –4.1) in the 4200 IU/week, 16 800 IU/week and 28 000 IU/week groups, respectively; n=645); effects were slightly attenuated after adjustment for inflammation (n=510). There were no effects of vitamin D on other iron biomarkers among women at delivery or infants aged 6 months. Conclusion These findings do not support improvement of iron status by vitamin D. The effect of prenatal vitamin D supplementation on ferritin may reflect an anti-inflammatory mechanism.

Background Research on menstrual hygiene management practices (MHMP) has yet to be conducted among adolescent girls in Bangladesh who have gained services from the Urban Primary Health Care Project (UPHCP). This study aimed to assess the effects of behavioural change communication activities on MHMP among urban school adolescent girls. Methods A convenience sample of 270 adolescent girls (aged 10–19) who had no chronic diseases from 5 schools in Dhaka city was selected using a descriptive cross-sectional design from February to May 2018. A semistructured (interviewer-administered) questionnaire was used. Frequencies were calculated for descriptive analysis. Results About 17% of girls had irregular menstrual cycles, 57% felt uneasy and 27% had >7 days of menstrual flow. Fifty-five per cent of the girls used sanitary napkins. Most (95%) and 26% of the girls did not change their pads during school and at night, respectively. Sixty-five per cent of girls disposed of the used pads at the public dustbin, and 83% bathed during menstrual. Only 4% of girls were aware of the iron folic acid tablets. Conclusions Despite the availability of services from UPHCP, the acceptance and adherence to MHMP among adolescent girls still need to be improved.

Introduction Previous studies in humans and rats suggest that erythritol might positively affect vascular function, xylitol decrease visceral fat mass and both substances improve glycaemic control. The objective of this study was to investigate the impact of a 5-week intake of erythritol and xylitol on vascular function, abdominal fat and blood lipids, glucose tolerance, uric acid, hepatic enzymes, creatinine, gastrointestinal tolerance and dietary patterns in humans with obesity. Methods Forty-two participants were randomised to consume either 36 g erythritol, 24 g xylitol, or no substance daily for 5 weeks. Before and after the intervention, arterial stiffness (pulse wave velocity, arteriolar-to-venular diameter ratio), abdominal fat (liver volume, liver fat percentage, visceral and subcutaneous adipose tissue, blood lipids), glucose tolerance (glucose and insulin concentrations), uric acid, hepatic enzymes, creatinine, gastrointestinal tolerance and dietary patterns were assessed. Data were analysed by linear mixed effect model. Results The 5-week intake of erythritol and xylitol showed no statistically significant effect on vascular function. Neither the time nor the treatment effects were significantly different for pulse wave velocity (time effect: p=0.079, Cohen’s D (95% CI) −0.14 (−0.54–0.25); treatment effect: p=0.792, Cohen’s D (95% CI) control versus xylitol: −0.11 (–0.61–0.35), control versus erythritol: 0.05 (0.44–0.54), erythritol versus xylitol: 0.07 (–0.41–0.54)). There was no statistically significant effect on abdominal fat, glucose tolerance, uric acid, hepatic enzymes and creatinine. Gastrointestinal tolerance was good except for a few diarrhoea-related symptoms. Participants of all groups reduced their consumption of sweetened beverages and sweets compared with preintervention. Conclusions The 5-week intake of erythritol and xylitol showed no statistically significant effects on vascular function, abdominal fat, or glucose tolerance in people with obesity.

Introduction Tooth extraction due to dental caries is associated with socioeconomic deprivation and is a major reason for elective childhood hospital admissions in England. Consumption of sugar-sweetened beverages is a risk factor for dental caries. We examined whether the soft drinks industry levy (SDIL), announced in March 2016 and implemented in April 2018, was associated with changes in incidence rates of hospital admissions for carious tooth extraction in children, 22 months post-SDIL implementation. Methods Changes in incidence rates of monthly National Health Service hospital admissions for extraction of teeth due to a primary diagnosis of dental caries (International Classification of Diseases; ICD-10 code: K02) in England, between January 2012 and February 2020, were estimated using interrupted time series and compared with a counterfactual scenario where SDIL was not announced or implemented. Periodical changes in admissions, autocorrelation and population structure were accounted for. Estimates were calculated overall, by Index of Multiple Deprivation (IMD) fifths and by age group (0–4 years, 5–9 years, 10–14 years, 15–18 years). Results Compared with the counterfactual scenario, there was a relative reduction of 12.1% (95% CI 17.0% to 7.2%) in hospital admissions for carious tooth extractions in all children (0–18 years). Children aged 0–4 years and 5–9 years had relative reductions of 28.6% (95% CI 35.6% to 21.5%) and 5.5% (95% CI 10.5% to 0.5%), respectively; no change was observed for older children. Reductions were observed in children living in most IMD areas regardless of deprivation. Conclusion The UK SDIL was associated with reductions in incidence rates of childhood hospital admissions for carious tooth extractions, across most areas regardless of deprivation status and especially in younger children.

Introduction Deteriorating mobility and falls reduce independence and quality of life for older people receiving aged care services. This trial aims to establish effectiveness on the mobility of older people, and explore cost-effectiveness and implementation of a telehealth physiotherapy programme. Method and analysis This type 1 hybrid effectiveness-implementation randomised controlled trial will involve 240 people aged 65+ years receiving aged care services in community or residential settings. Participants will be randomised to either: (1) the Telehealth Physiotherapy for Older People (TOP UP) Program or (2) a wait-list control group. The 6-month intervention includes 10 physiotherapy sessions delivered by videocall (Zoom). The intervention will include the local support of an aged care worker and online exercise resources. Primary outcome is mobility at 6 months post randomisation measured by the Short Physical Performance Battery. Secondary outcomes include rate of falls, sit-to-stand, quality of life, and goal attainment at 6 months after randomisation. Regression models will assess the effect of group allocation on mobility and the other continuously scored secondary outcomes, adjusting for baseline scores. The number of falls per person over 6 months will be analysed using negative binomial regression models to estimate between-group differences. An economic analysis will explore the cost-effectiveness of the TOP UP programme compared with usual care. Implementation outcomes and determinants relating to the intervention’s reach, fidelity, exercise dose delivered, adoption, feasibility, acceptability, barriers and facilitators will be explored using mixed methods. Conclusion This is the first trial to investigate the effectiveness, cost-effectiveness and implementation of a physiotherapy intervention in aged care delivered solely by telehealth internationally. The study has strong aged care co-design and governance and is guided by steering and advisory committees that include staff from aged care service providers and end-users. Trial results will be disseminated via peer-reviewed articles, conference presentations and lay summaries. Trial registration number The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN 12621000734864).

Objective To systematically map nutrition content in medical curricula across all 23 medical schools in Australia and New Zealand accredited by the Australian Medical Council (AMC). Methods A cross-sectional content analysis was conducted. Learning outcomes for 20 AMC-accredited medical curricula were extracted from online repositories and directly from universities in February to April 2021. Nutrition relevant learning outcomes or equivalent learning objectives/graduate attributes were identified. Nutrition learning outcomes were analysed according to Bloom’s revised taxonomy to determine whether outcomes met cognitive, psychomotor or affective domains and at what level. Results Of the total 23 AMC-accredited medical curricula, 20 medical schools had learning outcomes able to be sourced for analysis. A total of 186 nutrition learning outcomes were identified within 11 medical curricula. One medical school curriculum comprised 129 of 186 (69.4%) nutrition learning outcomes. The majority of outcomes (181, 97.3%) were in the cognitive domain of Bloom’s revised taxonomy, predominantly at level 3 ‘applying’ (90, 49.7%). The psychomotor domain contained five nutrition learning outcomes (5, 2.7%), while the affective domain contained none. New Zealand medical curricula (153, 82.3%) contained 4.6-fold more nutrition learning outcomes than Australian curricula (33, 17.7%). When comparing clinical and preclinical years across curricula, the proportion of learning outcomes in the psychomotor domain was 3.7-fold higher in clinical years (4.08%) versus preclinical years (1.15%). Conclusion There is wide variation across medical curricula regarding the number of nutrition learning outcomes. This may lead to varying competency of medical graduates to provide nutrition care in Australia and New Zealand.

The majority of outcomes (181, 97.3%) were in the cognitive domain of Bloom’s revised taxonomy, predominantly at level 3 ‘applying’ (90, 49.7%). The psychomotor domain contained five nutrition learning outcomes (5, 2.7%), while the affective domain contained none. New Zealand medical curricula (153, 82.3%) contained 4.6-fold more nutrition learning outcomes than Australian curricula (33, 17.7%). When comparing clinical and preclinical years across curricula, the proportion of learning outcomes in the psychomotor domain was 3.7-fold higher in clinical years (4.08%) versus preclinical years (1.15%). Conclusion There is wide variation across medical curricula regarding the number of nutrition learning outcomes. This may lead to varying competency of medical graduates to provide nutrition care in Australia and New Zealand.","PeriodicalId":36307,"journal":{"name":"BMJ Nutrition, Prevention and Health","volume":" 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135241681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background Although several lifestyle intervention studies have been conducted in low/middle-income countries, there were no such studies in Nepal. Therefore, a group-based culturally tailored Diabetes Prevention Education Program (DiPEP) was conducted recently. The study aimed to evaluate the effect of DiPEP in glycated haemoglobin (HbA1c), weight, waist circumference, physical activity and diet among population with pre-diabetes. Method A two-arm cluster randomised controlled trial was conducted in 12 clusters of two urban areas in Nepal. The DiPEP was a 6 month intervention (four 1-hour weekly educational sessions and 5 months of follow-up by community health workers/volunteers (CHW/Vs)). A postintervention assessment was done after 6 months. Linear mixed model was used to estimate the mean difference in primary outcome (HbA1c) and secondary outcomes (weight, waist circumference, physical activity and diet) between intervention and control arms, adjusted for baseline measure. Results In intention-to-treat analysis with a total of 291 participants, the estimated mean difference in HbA1c was found to be 0.015 percentage point (95% CI −0.074 to 0.104) between the intervention arm and the control arm, while it was −0.077 (95% CI −0.152 to −0.002) among those who attended at least 3 out of 4 educational sessions. The estimated mean difference in weight (in participants who attended ≥1 educational session) was −1.6 kg (95% CI −3.1 to −0.1). A significantly lower grain consumption was found in intervention arm (−39 g/day, 95% CI −65 to −14) compared with the control arm at postintervention assessment. Conclusion Although compliance was affected by COVID-19, individuals who participated in ≥3 educational sessions had significant reduction in HbA1c and those who attended ≥1 educational session had significant weight reduction. Grain intake was significantly reduced among the intervention arm than the control arm. Hence, group-based lifestyle intervention programmes involving CHW/vs is recommended for diabetes prevention.

背景:虽然在中低收入国家进行了一些生活方式干预研究，但在尼泊尔没有这样的研究。因此，最近开展了一项基于群体的文化定制糖尿病预防教育计划(DiPEP)。该研究旨在评估DiPEP对糖尿病前期人群糖化血红蛋白(HbA1c)、体重、腰围、身体活动和饮食的影响。方法采用两组随机对照试验，选取尼泊尔2个城市地区的12个聚类。DiPEP是一个为期6个月的干预(4次每周1小时的教育课程和5个月的社区卫生工作者/志愿者(CHW/Vs)的随访)。6个月后进行干预后评估。采用线性混合模型估计干预组和对照组之间主要结局(HbA1c)和次要结局(体重、腰围、体力活动和饮食)的平均差异，并根据基线测量进行调整。在总共291名参与者的意向治疗分析中，干预组和对照组的HbA1c估计平均差异为0.015个百分点(95% CI - 0.074至0.104)，而在至少参加了4次教育课程中的3次的患者中，HbA1c的估计平均差异为- 0.077 (95% CI - 0.152至- 0.002)。估计体重的平均差异(参加≥1次教育课程的参与者)为- 1.6 kg (95% CI为- 3.1至- 0.1)。在干预后评估中，与对照组相比，干预组的谷物消耗量显著降低(- 39 g/天，95% CI为- 65至- 14)。结论尽管依从性受到COVID-19的影响，但参加≥3次教育课程的个体HbA1c显著降低，参加≥1次教育课程的个体体重显著减轻。与对照组相比，干预组的谷物摄入量明显减少。因此，建议以群体为基础的生活方式干预方案，包括CHW/vs预防糖尿病。试验注册号NCT04074148。

Women’s roles in the US military have progressively changed over the past several decades. Previously women were barred from combat roles. Recent change in policy allow women into combat roles in the Marine Corps, and this has led to women being trained for combat specialties. Objectives This observational cross-sectional study describes body composition and performance values for modern Marine Corps women. Methods Volunteers were 736 Marine women who were assessed for body composition and physical performance; (age 29.5±7.3 (18–56) years; height 163.6±6.8 (131.0–186.1) cm; body mass 68.3±9.2 (42.0–105.3) kg; years in the military 8.9±6.8 (0.5–37) years-in-service). Body composition measures were obtained using dual-energy X-ray absorptiometry and single-frequency bioelectrical impedance analyses. Performance measures were obtained from official physical and combat fitness test scores (PFT; CFT) as well as from data on measured countermovement jumps (CMJ) on a calibrated force platform. Results Mean body composition metrics for Marine women were: 47.5±5.7 fat free mass (FFM) (kg), 30.1%±6.4% body fat (%BF), 2.6±0.3 bone mineral content (kg), and 25.5±2.8 body mass index (kg/m 2 ); performance metrics included 43.4±3.2 maximal oxygen uptake (VO2max; mL.kg.min), 22.4±7.1 CMJ height (cm) and 2575±565.2 CMJ peak power (W). Data showed strong correlations (r) (≥0.70) between PFT and VO2max scores (0.75), and moderate correlations (≥0.50) between CFT and VO2max scores (0.57), CFT and PFT scores (0.60), FFM and CMJ peak power (W) (0.68), and %BF to VO2max (−0.52), PFT (−0.54), CMJ-Ht (−0.52) and CMJ relative power (W/kg) (−0.54). Conclusion Modern Marine women are both lean and physically high performing. Body composition is a poor predictor of general physical performance.

Background A healthful plant-based diet was associated with lower risks of coronary heart disease and type 2 diabetes, and a favourable profile of adiposity-associated biomarkers, while an unhealthful plant-based diet was associated with elevated risk of cardiometabolic disease in health professional populations. However, little is known about the associations between plant-based dietary patterns and risk of cardiovascular disease (CVD) in US veterans. Methods The study population consisted of 148 506 participants who were free of diabetes, CVD and cancer at baseline in the Veterans Affairs (VA) Million Veteran Program. Diet was assessed using a Food Frequency Questionnaire at baseline. We calculated an overall Plant-Based Diet Index (PDI), a healthful PDI (hPDI) and an unhealthful PDI (uPDI). The CVD endpoints included non-fatal myocardial infarction (MI) and acute ischaemic stroke (AIS) identified through high-throughput phenotyping algorithms approach and fatal CVD events identified by searching the National Death Index. Results With up to 8 years of follow-up, we documented 5025 CVD cases. After adjustment for confounding factors, a higher PDI was significantly associated with a lower risk of CVD (HR comparing extreme quintiles=0.75, 95% CI 0.68 to 0.82, P trend <0.0001). We observed an inverse association between hPDI and the risk of CVD (HR comparing extreme quintiles=0.71, 95% CI 0.64 to 0.78, P trend <0.001), whereas uPDI was positively associated with the risk of CVD (HR comparing extreme quintiles=1.12, 95% CI 1.02 to 1.24, P trend <0.001). We found similar associations of hPDI with subtypes of CVD; a 10-unit increment in hPDI was associated with HRs (95% CI) of 0.81 (0.75 to 0.87) for fatal CVD, 0.86 (0.79 to 0.94) for non-fatal MI and 0.86 (0.78 to 0.95) for non-fatal AIS. Conclusions Plant-based dietary pattern enriched with healthier plant foods was associated with a substantially lower CVD risk in US veterans.
健康的植物性饮食与较低的冠心病和2型糖尿病风险以及有利的脂肪相关生物标志物相关，而在卫生专业人群中，不健康的植物性饮食与心脏代谢疾病风险升高相关。然而，在美国退伍军人中，人们对植物性饮食模式与心血管疾病(CVD)风险之间的关系知之甚少。方法研究人群包括1448506名在退伍军人事务(VA)百万退伍军人计划基线时无糖尿病、心血管疾病和癌症的参与者。基线时使用食物频率问卷对饮食进行评估。我们计算了总体植物性饮食指数(PDI)、健康PDI (hPDI)和不健康PDI (uPDI)。CVD终点包括通过高通量表型算法确定的非致死性心肌梗死(MI)和急性缺血性卒中(AIS)，以及通过搜索国家死亡指数确定的致死性CVD事件。结果在长达8年的随访中，我们记录了5025例CVD病例。校正混杂因素后，较高的PDI与较低的CVD风险显著相关(HR比较极端五分位数=0.75,95% CI 0.68至0.82,P趋势<0.0001)。我们观察到hPDI与CVD风险呈负相关(HR比较极端五分位数=0.71,95% CI 0.64至0.78,P趋势<0.001)，而uPDI与CVD风险呈正相关(HR比较极端五分位数=1.12,95% CI 1.02至1.24,P趋势<0.001)。我们发现hPDI与CVD亚型有类似的关联;10个单位的hPDI增加与致死性心血管疾病的hr (95% CI)相关，非致死性心肌梗死为0.86(0.79至0.94)，非致死性AIS为0.86(0.78至0.95)。结论:富含健康植物性食物的植物性饮食模式与美国退伍军人心血管疾病风险显著降低相关。
