ABSTRACT

OBJECTIVE: We aimed to capture General Dental Practitioners' (GDPs) views on delivering dietary advice to older adults in combination with treatment to replace missing teeth and identify solutions to help inform the development and implementation of future dietary interventions within primary dental care. BACKGROUND: As natural teeth are lost, older adults may need to choose softer, more manageable foods which might be of lower nutrient density. Previous research has indicated that prosthodontic rehabilitation can improve masticatory function but not the intake of nutrients, highlighting a potential need for a combined approach of oral rehabilitation and dietary counselling. MATERIALS AND METHODS: Semi-structured telephone interviews were conducted with a purposive sampling strategy of 12 GDPs. Interviews were digitally recorded and transcribed verbatim. An iterative coding process using theme-analytic methods was used. RESULTS: Twelve interviews were conducted with GDPs in the United Kingdom. The themes that emerged from the interviews included: the awareness of the importance of dietary advice among GDPs; the concerns GDPs had on patients' adherence to dietary advice; uncertainty over roles and responsibilities in the provision of dietary advice; and the limited time and remuneration for dietary advice in dental practice. A minor theme identified was the motivation of GDPs to implement dietary advice alongside oral rehabilitation. All reported that they were already providing dietary advice to their patients but that this was limited to caries prevention. CONCLUSION: The GDPs interviewed expressed positive attitudes towards providing dietary advice alongside oral rehabilitation for older adults. However, a lack of confidence, awareness, time and remuneration are barriers to its provision in primary dental care. To facilitate the implementation of dietary advice alongside oral rehabilitation, clear guidance on and training in delivering dietary advice and multidisciplinary cooperation are required.

ABSTRACT

BACKGROUND: Childhood obesity is associated with serious comorbidities during childhood and into adulthood. One potential risk factor for childhood obesity is consumption of unhealthy, energy-dense foods. This scoping review examines evidence on snacking in children aged 2-12 years of age and presents the patterns and position of snacking in children's diets. METHODS: A search of electronic databases (MEDLINE, Web of Science, PubMed, Embase) for articles published from March 2011 to November 2022 was conducted. Articles providing insight into the position of snacking (e.g., energy contribution), or patterns (e.g., location, timing), in children aged 2-12 years were included. A quality assessment was conducted and data was synthesised according to data source (nationally representative or other). RESULTS: Twenty-one articles were included, most (n = 13) reporting nationally representative data. The average number of daily snacks was 3, with 92.9-100.0% of children consuming snacks. Most were consumed in the afternoon (75.2-84.0%) and at home (46.5-67.3%). Snacks frequently consumed were 'fruits and vegetables', 'baked desserts', 'sweets, candy and confectionery', and 'dairy products'. Snacks contributed 231-565 kcal daily, up to a third of daily carbohydrate intake, a quarter of fat intake, and a fifth of protein intake. Snacks provided up to one third of vitamin C intake, one quarter of vitamin E, potassium and magnesium intake, and a fifth of calcium, folic acid, vitamins D and B12, iron and sodium intake. DISCUSSION: This scoping review provides insight into patterns and position of snacking within children's diets. Snacking plays a significant role in children's diets with multiple snacking occasions occurring throughout a child's day, the overconsumption of which has the potential to increase risk of childhood obesity. Further research is required into the role of snacking, particularly specific foods playing a role in micronutrient intake, and clear guidance for snacking intake in children.

ABSTRACT

Modifying food texture and eating slowly each reduce appetite and energy intake. No study has evaluated the effect of combining these measures to slow eating speed and determine the effect on appetite. The aim of this study was to investigate whether there is a combined effect of manipulating oral processing behaviours (OPBs) in this manner on self-reported satiety and subsequent food intake. A 2 × 2 design was used with four breakfast conditions in total. Twenty-four participants attended four study visits where they were asked to consume one of two isocaloric fixed-portion breakfasts differing in texture: 1) granola with milk and 2) yogurt with muesli and conserve. Participants consumed each breakfast twice, with verbal instructions to chew slowly at one visit and at a normal rate at another. Consumption was video-recorded to behaviourally code OPBs. Participants completed visual analogue scales of self-reported appetite measures at the beginning of the test session, immediately prior to and immediately after breakfast consumption. They also completed a food diary documenting food intake for the remainder of the day. The breakfast designed to be eaten slowest (the harder-textured meal with instructions to eat slowly) was eaten at a slower rate, with a greater number of chews per bite and a slower bite rate (p < 0.001) compared to the other meals. No differences were observed between the breakfast conditions on subjective measures of post-prandial satiety, or subsequent energy or macronutrient consumption. Results of this study highlight that combined effects of texture and instructions are most effective at reducing eating rate, though eating slower was not shown to enhance post-meal satiety. Reduced eating speed has previously been shown to reduce ad-libitum energy intake. Future research should consider combined approaches to reduce eating speed, to mitigate the risk of overconsumption within meals.

ABSTRACT

An ageing population presents significant nutritional challenges, particularly for partially dentate adults. This two-armed pilot randomised controlled trial (RCT) compared habit formation (automaticity) for healthy eating behaviours between control and intervention groups after participation in a habit-based dietary intervention for older adults, following oral rehabilitation in the United Kingdom (UK). n = 54 participants were randomised to receive a habit-based dietary intervention (intervention group n = 27, IG) or standard dietary advice in a leaflet (control group n = 27, CG). The IG attended three sessions over six weeks, which focused on habit formation for three healthy eating behaviours (increasing fruit and vegetables, wholegrains, and healthy proteins). Participants were assessed for habit strength (using the Self-Report Behavioural Automaticity Index (SRBAI)) alongside health and nutrition outcomes at six weeks, four months and eight months. Forty-nine participants completed all follow-up visits. The IG compared to the CG had significant increases in automaticity at six weeks, four months (primary outcome) and eight months for eating ≥3 portions of fruit and vegetables; choosing wholegrain sources over white alternatives, and choosing healthy protein sources over red/processed meat. The mean change in the Mini Nutritional Assessment total score was greater in the IG compared with the CG at six weeks only (p = 0.03). A habit-based dietary intervention following oral rehabilitation increased automaticity for healthy dietary behaviours, which could translate into clinically meaningful benefits in this cohort of older adults.

ABSTRACT

OBJECTIVES: (1) Explore the challenges of providing daily oral care in care homes; (2) understand oral care practices provided by care home staff; (3) co-design practical resources supporting care home staff in these activities. METHODS: Three Sheffield care homes were identified via the "ENRICH Research Ready Care Home Network," and three to six staff per site were recruited as co-design partners. Design researchers led three co-design workshops exploring care home staff's experiences of providing daily oral care, including challenges, coping strategies and the role of current guidelines. New resources were prototyped to support the use of guidelines in practice. The design researchers developed final resources to enable the use of these guidelines in-practice-in-context. FINDINGS: Care home staff operate under time and resource constraints. The proportion of residents with dementia and other neurodegenerative conditions is rapidly increasing. Care home staff face challenges when residents adopt "refusal behaviours" and balancing daily oral care needs with resident and carer safety becomes complex. Care home staff have developed many coping strategies to navigate "refusal behaviours." Supporting resources need to "fit" within the complexities of practice-in-context. CONCLUSIONS: The provision of daily oral care practices in care homes is complex and challenging. The co-design process revealed care home staff have a "library" of context-specific practical knowledge and coping strategies. This study offers insights into the process of making guidelines usable for professionals in their contexts of practice, exploring the agenda of implementing evidence-based guidelines.

ABSTRACT

OBJECTIVES: Maintaining the oral health of dependent older adults is challenging, with limited access to dental care and limited focus on preventive oral health programmes. This study aimed to evaluate the attitudes of General Dental Practitioners (GDPs), working in Switzerland, to caring for dependent older adults with a focus on the use of silver diamine fluoride (SDF) as a caries preventive agent and more widely on the provision of domiciliary dental care (DDC). METHODS: Seventeen GDPs working in Switzerland were interviewed. Each interview was semi-structured by a topic guide, digitally recorded, and transcribed. The transcribed data were analysed using a thematic analysis. RESULTS: Three major themes to the widespread use of SDF in this population were identified: lack of basic knowledge including indications for use; aesthetic concerns and product availability. Those who had knowledge about the product believed that using it in the treatment of frail older adults had advantages, especially in the preservation and/or prolongation of the life of teeth without invasive treatments. The biggest barrier was its availability. The GDPs identified three major barriers related to DDC provision: lack of infrastructure, poor financial rewards and safety concerns (patient and operator safety). Those who provided this service stated that they were doing it because of self-motivation, kindness, or as a role in community service. CONCLUSIONS: The potential use of SDF was viewed positively by the majority of the GDPs interviewed but confusion exists over its availability in Switzerland, and other barriers were identified to more widespread use in this patient group. The GDPs interviewed in this study reported that a lack of infrastructure and a low level of remuneration continue to be barriers to more of them undertaking DDC for dependent older adults.

ABSTRACT

Health claims on food labelling can influence peoples' perception of food without them actually eating it, for example driving a belief that a particular food will make them feel fuller. The aim of this study was to investigate whether nutrient and health claims on food labelling can influence self-reported, and physiological indicators of, satiation. A total of 50 participants attended two visits where they were asked to consume a 380 kcal breakfast (granola and yogurt) labelled as a 500 kcal 'indulgent' breakfast at one visit and as a 250 kcal 'sensible' breakfast at the other. The order of the breakfast descriptions was randomly allocated. Participants were unaware that the two breakfasts were the same product and that only the food labels differed. At each visit blood samples were collected to measure gut hormone levels (acylated ghrelin, peptide tyrosine-tyrosine and glucagon-like peptide-1) at three time points: 20 min after arrival (baseline), after 60 min (anticipatory, immediately prior to consumption) and after 90 min (post-consumption). Visual analogue scales measuring appetite (hunger, satiety, fullness, quantity and desire to eat) were completed prior to each sample. Between 60 and 90 min, participants consumed the breakfast and rated its sensory appeal. Participants reported a higher mean change in self-reported fullness for the 'indulgent' than the 'sensible' breakfast from anticipatory to post-consumption (mean difference: 7.19 [95% CI: 0.73, 13.6]; p = 0.030). This change was not observed for the other appetite measures at the other time points or gut hormone levels. This study suggests that nutrient and health claims on food labels may influence satiation as measured by self-reported fullness. It also suggests that the observed differences in satiety scores are not due to changes in the main appetite regulating gut hormones, but are more likely centrally mediated. More high-quality trials are required to confirm these findings.

ABSTRACT

OBJECTIVE: To examine effectiveness, cost effectiveness, generalisability, and acceptability of financial incentives for smoking cessation during pregnancy in addition to variously organised UK stop smoking services. DESIGN: Pragmatic, multicentre, single blinded, phase 3, randomised controlled trial (Cessation in Pregnancy Incentives Trial phase 3 (CPIT III)). SETTING: Seven UK stop smoking services provided in primary and secondary care facilities in Scotland, Northern Ireland, and England. PARTICIPANTS: 944 pregnant women (age ≥16 years) who self-reported as being smokers (at least one cigarette in the past week) when asked at first maternity visit, less than 24 weeks' gestation, and notified to the trial team by routine stop smoking services. INTERVENTIONS: Participants in the control group were offered the standard stop smoking services, which includes the offer of counselling by specially trained workers using withdrawal orientated therapy and the offer of free nicotine replacement therapy. The intervention was the offer of usual support from the stop smoking services and the addition of up to £400 ($440; €455) of LoveToShop financial voucher incentives for engaging with current stop smoking services or to stop smoking, or both, during pregnancy. MAIN OUTCOME MEASURES: Self-reported smoking cessation in late pregnancy (between 34 and 38 weeks' gestation) corroborated by saliva cotinine (and anabasine if using nicotine replacement products). Results were adjusted for age, smoking years, index of multiple deprivation, Fagerström score, before or after covid, and recruitment site. Secondary outcomes included point and continuous abstinence six months after expected date of delivery, engagement with stop smoking services, biochemically validated abstinence from smoking at four weeks after stop smoking date, birth weight of baby, cost effectiveness, generalisability documenting formats of stop smoking services, and acceptability to pregnant women and their carers. RESULTS: From 9 January 2018 to 4 April 2020, of 4032 women screened by stop smoking services, 944 people were randomly assigned to the intervention group (n=471) or the control group (n=470). Three people asked for their data to be removed. 126 (27%) of 471 participants stopped smoking from the intervention group and 58 (12%) of 470 from the control group (adjusted odds ratio 2.78 (1.94 to 3.97) P<0.001). Serious adverse events were miscarriages and other expected pregnancy events requiring hospital admission; all serious adverse events were unrelated to the intervention. Most people who stopped smoking from both groups relapsed after their baby was born. CONCLUSIONS: The offer of up to £400 of financial voucher incentives to stop smoking during pregnancy as an addition to current UK stop smoking services is highly effective. This bolt-on intervention supports new guidance from the UK National Institute for Health and Care Excellence, which includes the addition of financial incentives to support pregnant women to stop smoking. Continuing incentives to 12 months after birth is being examined to prevent relapse. TRIAL REGISTRATION: ISRCTN Registry ISRCTN15236311.

ABSTRACT

BACKGROUND: Dental service provision in the care home sector is poor, with little emphasis on prevention. Emerging evidence suggests that the use of Dental Care Professionals (dental therapists and dental nurses) as an alternative to dentists has the potential to improve preventive advice, the provision of care and access to services within care homes. However, robust empirical evidence from definitive trials on how to successfully implement and sustain these interventions within care homes is currently lacking. The aim of the study is to determine whether Dental Care Professionals could reduce plaque levels of dentate older adults (65 + years) residing in care homes. METHODS: This protocol describes a two-arm cluster-randomised controlled trial that will be undertaken in care homes across Wales, Northern Ireland and England. In the intervention arm, the dental therapists will visit the care homes every 6 months to assess and then treat eligible residents, where necessary. All treatment will be conducted within their Scope of Practice. Dental nurses will visit the care homes every month for the first 3 months and then three-monthly afterwards to promulgate advice to improve the day-to-day prevention offered to residents by carers. The control arm will be 'treatment as usual'. Eligible care homes (n = 40) will be randomised based on a 1:1 ratio (20 intervention and 20 control), with an average of seven residents recruited in each home resulting in an estimated sample of 280. Assessments will be undertaken at baseline, 6 months and 12 months and will include a dental examination and quality of life questionnaires. Care home staff will collect weekly information on the residents' oral health (e.g. episodes of pain and unscheduled care). The primary outcome will be a binary classification of the mean reduction in Silness-Löe Plaque Index at 6 months. A parallel process evaluation will be undertaken to explore the intervention's acceptability and how it could be embedded in standard practice (described in a separate paper), whilst a cost-effectiveness analysis will examine the potential long-term costs and benefits of the intervention. DISCUSSION: This trial will provide evidence on how to successfully implement and sustain a Dental Care Professional-led intervention within care homes to promote access and prevention. TRIAL REGISTRATION: ISRCTN16332897 . Registered on 3 December 2021.

ABSTRACT

AIM: To examine the cross-sectional associations between single nutrient intakes and posteriori nutrient-based dietary patterns and periodontal disease risk in a subset of the UK Biobank cohort. MATERIALS AND METHODS: Dietary data were collected by 24-h dietary recall on up to five separate occasions over 16 months. A touchscreen questionnaire was used to collect oral health information. Participants were considered at high risk of periodontal disease if they reported having painful gums and/or bleeding gums and/or loose teeth. Principal component analysis identified four nutrient-based dietary patterns from 20 nutrients. Logistic regression was used to estimate the odds ratio of periodontal disease risk for single nutrients and nutrient-based dietary patterns. RESULTS: A total of 9476 participants (mean age 56.2 years [SD 8.0]) were included in the analysis. Higher intakes of vitamin B6, B12, C, and E, folate, iron, potassium, magnesium, polyunsaturated fatty acids, and total sugar were associated with a lower risk of periodontal disease. Higher intake of saturated fat was associated with an increased risk. A dietary pattern characterized by high micronutrients and fibre intake was associated with low risk of periodontal disease. CONCLUSION: Within this sample of middle-aged and older adults, a "high micronutrient and fibre" dietary pattern was associated with reduced risk of periodontal disease.

ABSTRACT

OBJECTIVE: To evaluate the effectiveness of professionally applied fluoride varnish on the incidence of dental caries amongst older adults resident in LTCFs in Northern Ireland. BACKGROUND: The oral health status of older adults within Long-Term Care Facilities (LTCFs) is significantly worse than their community living peers. Whilst evidence suggests an important role for fluoride varnish in preventing caries in this population, very few studies have evaluated this intervention. MATERIALS AND METHODS: A quality improvement project was undertaken with dentate residents (n = 190) in nine LTCFs who had fluoride varnish applied by Dental Care Professionals on two separate occasions during a 12-month period (intervention group). Nine LTCFs were chosen as matched controls (control group) with comparable numbers of residents of similar medical status (n = 217). For the intervention group, oral hygiene training was also provided for the care home staff. RESULTS: A total of 407 patients (n = 271 female) were included in the analyses (mean age [SD]: 84.1 [6.6] years). After 12 months, the intervention group recorded a significant reduction in mean number of carious teeth (mean [95% CI]: -0.85 [-1.12, -0.58]; P < .001). Patients in the control group had significant increases in the mean number of carious teeth (mean [95% CI]: 0.21 [0.05, 0.37]; P = .012), mean plaque score (mean [95% CI]: 1.16 [0.28, 2.04]; P = .010) and mean DMFT score (mean [95% CI]: 0.13 [0.04, 0.22]; P = .004). CONCLUSIONS: This study demonstrates the potential role of fluoride varnish in combination with oral hygiene training for staff in the prevention and arrest of carious lesions among older adults in LTCFs.

ABSTRACT

OBJECTIVE: Many older patients, housebound or living in long-term care facilities (LTCFs) have limited access to dental care. This descriptive qualitative study aimed to understand general dental practitioners (GDPs) attitudes and perceived barriers to undertaking Domiciliary Dental Care (DDC) for those patients in Northern Ireland (NI). METHODS: Semi-structured telephone interviews were conducted with a purposive sample of 12 GDPs in Northern Ireland. Interviews were digitally recorded and transcribed verbatim. An iterative coding process using theme-analytic methods was used. RESULTS: The data were characterised into four major themes-risk of professional litigation, remuneration for those undertaking DDC, complexity of treatment, and the overall framework of the dental care system in NI. Two minor themes identified were practice culture and reasons for undertaking DDC. The GDPs in the study identified a number of barriers to undertaking DDC including a legal requirement to transport oxygen, lack of organisation and limited oral hygiene care provision in LTCFs, and confusion around their responsibilities for provision of DDC. Those GDPs who were providing DDC indicated that they did so out of kindness and a sense of loyalty to their long-standing patients. CONCLUSION: The GDPs in this study identified a number of significant barriers to provision of DDC at organisational, structural and clinical levels. The GDPs indicated that they required clarification of their responsibilities around DDC with clear guidelines necessary given the increase in demand for this service.

ABSTRACT

BACKGROUND: Evidence for interventions promoting oral health amongst care home residents is weak. The National Institute for Health and Care Excellence (NICE) guideline NG48 aims to maintain and improve the oral health of care home residents. A co-design process that worked with residents and care home staff to understand how the NG48 guideline could be best implemented in practice has been undertaken to refine a complex intervention. The aim of this study is to assess the feasibility of the intervention to inform a future larger scale definitive trial. METHODS: This is a protocol for a pragmatic cluster randomised controlled trial with a 12-month follow-up that will be undertaken in 12 care homes across two sites (six in London, six in Northern Ireland). Care homes randomised to the intervention arm (n = 6) will receive the complex intervention based on the NG48 guideline, whilst care homes randomised to the control arm (n = 6) will continue with routine practice. The intervention will include a training package for care home staff to promote knowledge and skills in oral health promotion, the use of the Oral Health Assessment Tool on residents by trained care home staff, and a 'support worker assisted' daily tooth-brushing regime with toothpaste containing 1500 ppm fluoride. An average of ten residents, aged 65 years or over who have at least one natural tooth, will be recruited in each care home resulting in a recruited sample of 120 participants. Assessments will be undertaken at baseline, 6 months and 12 months, and will include a dental examination and questionnaires on general health and oral health administered by a research assistant. A parallel process evaluation involving semi-structured interviews will be undertaken to explore how the intervention could be embedded in standard practice. Rates of recruitment and retention, and intervention fidelity will also be recorded. A cost-consequence model will determine the relevance of different outcome measures in the decision-making context. DISCUSSION: The study will provide valuable information for trialists, policymakers, clinicians and care home staff on the feasibility and associated costs of oral health promotion in UK care homes.

ABSTRACT

BACKGROUND: Older adults suffering partial tooth loss may need additional intervention strategies other than natural tooth replacement alone to improve their nutritional status. This study aimed to design and develop a habit-based tailored dietary intervention and to assess the feasibility and acceptability of the intervention, in conjunction with natural tooth replacement, amongst partially dentate older adults. METHODS: The design and development of the dietary intervention (phase 1) consisted of analysis of the target population's dietary intake and qualitative research through focus groups with community-dwelling older adults (aged 65 years and over). The dietary intervention consisted of forming three healthy dietary habits around fruits and vegetables, wholegrains and healthy proteins. Feasibility of the intervention was then tested amongst older adults who had recently completed dental treatment for natural tooth replacement in a small non-randomised single arm study (phase 2). The principal feasibility outcome was the usability and acceptability of the intervention which was measured using evaluation questionnaires and by conducting post-intervention semi-structured interviews. Supporting outcomes consisted of feasibility of screening procedures, recruitment strategies and retention/attrition rates as well as the participant's compliance to the intervention assessed through self-monitoring tracking sheets. RESULTS: Twenty-one older adults (mean [SD] age 72.1 [10.4].) took part in one of four focus group discussions (phase 1). Twelve themes related to barriers (e.g. oral health, appetite) and facilitators (e.g. nutritional knowledge, retirement) of healthy eating guided intervention development, as did a further five themes when asked for direct intervention feedback. Nine older adult participants (mean [SD] age 72.5[9.7]) were recruited into the feasibility study (phase 2) where eight themes were identified from feedback interview discussions. The principal outcome measures identified intervention feasibility as participants considered the intervention acceptable and useable as both the evaluation questionnaire and qualitative interview results were overwhelmingly positive. As a supporting outcome measure, strong intervention compliance was also achieved. Screening procedures were accepted but additional recruitment strategies (e.g. incorporation of home study visits or recruitment via posters advertisement) may benefit future study enrolment and retention. CONCLUSION: Phase 1 and phase 2 findings have allowed for an iterative, user-driven intervention to be developed and refined for a randomised control study to evaluate the intervention's effectiveness.

ABSTRACT

BACKGROUND: Oral healthcare service provision for dependent older adults is often poor. For dental services to provide more responsive and equitable care, evidence-based approaches are needed. To facilitate future research, the development and application of a core outcome set would be beneficial. The aim of this study is to develop a core outcome set for oral health services research involving dependent older adults. METHODS: A multi-step process involving consensus methods and including key stakeholders will be undertaken. This will involve identifying potentially relevant outcomes through a systematic review of previous studies examining the effectiveness of strategies to prevent oral disease in dependent older adults, combined with semi-structured interviews with key stakeholders. Stakeholders will include dependent older adults, family members, carers, care-home managers, health professionals, researchers, dental commissioners and policymakers. To condense and prioritise the long list of outcomes generated by the systematic review and semi-structured interviews, a Delphi survey consisting of several rounds with key stakeholders, as mentioned above, will be undertaken. The 9-point Likert scale proposed by the GRADE Working Group will facilitate this consensus process. Following the Delphi survey, a face-to-face consensus meeting with key stakeholders will be conducted where the stakeholders will anonymously vote and decide on what outcomes should be included in the finalised core outcome set. DISCUSSION: Developing a core set of outcomes that are clinically and patient-centred will help improve the design, conduct and reporting of oral health services research involving dependent older adults, and ultimately strengthen the evidence base for high-quality oral health care for dependent older adults. TRIAL REGISTRATION: The study was registered with the COMET initiative on 9 January 2018 http://www.cometinitiative.org/studies/details/1081?result=true .

ABSTRACT

As natural teeth are lost, many older adults choose softer foods lacking in essential micronutrients and fiber, yet replacing missing teeth alone does not positively influence diet. Dietary intervention in combination with treatment to replace missing teeth is increasing, though understanding of effective intervention components is limited. This systematic review synthesized literature relating to oral rehabilitation coupled with dietary intervention in adults. The primary outcome was dietary intake; secondary outcomes pertained to oral health and dietary intervention characteristics including: theoretical basis and behavior change techniques (BCTs). MEDLINE, Web of Science, PubMed and CENTRAL were searched. Nine studies were included. Study designs were heterogeneous involving 526 participants. Narrative synthesis identified improvements in at least one aspect of participants' oral health (i.e. biting/chewing) alongside at least one positive diet/nutrition outcome post-intervention for all studies. F/V results were pooled for three studies using meta-analysis techniques resulting in a standardized mean difference (SMD) of 0.29 [CI -0.54, 1.12], p = 0.49, but with marked heterogeneity (p = 0.0007). Few interventions were theory-based and intervention components were poorly described. Overall, narrative synthesis indicated support for dietary intervention coupled with oral rehabilitation on diet. Meta-analysis was only possible with three studies highlighting limitations. Large-scale, appropriately described trial methodologies are needed.Trial registry: This review was prospectively registered with PROSPERO on the 11 July 2017 [CRD42017071075].

ABSTRACT

BACKGROUND: Many factors determine dietary intake in older adults, including physical health, psychological well-being and socio-economic status. Dental status may also be important. The aim was to examine how dental status impacts perceived ability to eat to certain foods, nutrient intake and nutritional status in UK older adults. METHODS: Data collected by the National Diet and Nutrition Survey Rolling Programme was analysed. A 4-day food diary assessed dietary intake, while a Computer Assisted Personal Interview collected socio-demographic, health behaviour and oral health information. Participants aged 65 years and over (n = 1053) were categorised into three groups according to their dental status: edentate with dentures (E-DEN, n = 292), dentate with dentures (D-DEN, n = 305) or dentate with no dentures (DEN, n = 456). A total of 515 participants provided a blood sample that was used to assess nutrient concentrations including vitamin B12, vitamin C, ferritin, vitamin B6 (pyridoxal-5-phosphate, PLP), retinol, ß-carotene and 25-hydroxyvitamin D (25-OH-D). Multiple regression methods were performed to examine cross-sectional associations between dental status, food selection, nutrient intake and nutritional status. RESULTS: Both E-DEN and D-DEN groups, compared with the DEN group, were more likely to report difficulty eating apples, raw carrots, lettuce, nuts, well-cooked steak and crusty bread (P < 0.01). No group differences were observed in perceived ability to eat sliced bread, sliced cooked meats and cheese. The E-DEN group compared with the DEN group had lower mean daily intakes of omega 3 fatty acids (P = 0.006), non-starch polysaccharides (P = 0.001), ß-carotene (P = 0.001), folate (P = 0.001), vitamin C (P = 0.008), magnesium (P < 0.001) and potassium (P < 0.001), and had lower plasma vitamin B6 PLP (P = 0.001), vitamin C (P = 0.009) and ß-carotene (P = 0.015) concentrations, after adjusting for socio-demographic and health behavioural factors. Compared with the DEN group, the D-DEN group did not have lower nutrient intakes or lower blood nutrient concentrations. CONCLUSIONS: Within this sample of older adults, impaired dental status appears to influence food selection, and intake of important nutrients. Future research should focus on developing dental interventions coupled with dietary counselling to encourage the adoption of healthy eating habits in this high-risk population group.

ABSTRACT

BACKGROUND: Exposure to aflatoxin, a mycotoxin produced by fungi that commonly contaminates cereal crops across sub-Saharan Africa, has been associated with impaired child growth. We investigated the impact of aflatoxin exposure on the growth of Gambian infants from birth to two years of age, and the impact on insulin-like growth factor (IGF)-axis proteins. METHODS: A subsample (N = 374) of infants from the Early Nutrition and Immune Development (ENID) trial (ISRCTN49285450) were included in this study. Aflatoxin-albumin adducts (AF-alb) were measured in blood collected from infants at 6, 12 and 18 months of age. IGF-1 and IGFBP-3 were measured in blood collected at 12 and 18 months. Anthropometric measurements taken at 6, 12, 18 and 24 months of age were converted to z-scores against the WHO reference. The relationship between aflatoxin exposure and growth was analysed using multi-level modelling. RESULTS: Inverse relationships were observed between lnAF-alb and length-for-age (LAZ), weight-for-age (WAZ), and weight-for-length (WLZ) z-scores from 6 to 18 months of age (ß = - 0·04, P = 0·015; ß = - 0·05, P = 0.003; ß = - 0·06, P = 0·007; respectively). There was an inverse relationship between lnAF-alb at 6 months and change in WLZ between 6 and 12 months (ß = - 0·01; P = 0·013). LnAF-alb at 12 months was associated with changes in LAZ and infant length between 12 and 18 months of age (ß = - 0·01, P = 0·003; ß = - 0·003, P = 0·02; respectively). LnAF-alb at 6 months was associated with IGFBP-3 at 12 months (r = - 0·12; P = 0·043). CONCLUSIONS: This study found a small but significant effect of aflatoxin exposure on the growth of Gambian infants. This relationship is not apparently explained by aflatoxin induced changes in the IGF-axis.

ABSTRACT

Aflatoxin, a human liver carcinogen, frequently contaminates groundnuts, maize, rice, and other grains, especially in Africa. The aim of this study was to evaluate the effectiveness of an educational intervention that involved training rural Gambian women on how to identify and remove moldy groundnuts to reduce aflatoxin B1 (AFB1) contamination. In total, 25 women, recruited from the West Kiang region of The Gambia, were trained on how to recognize and remove moldy groundnuts. Market-purchased groundnuts were hand sorted by the women. Groundnuts were sampled at baseline (n =5), after hand sorting ("clean," n =25 and "moldy," n =25), and after roasting (n =5). All samples were analyzed for AFB1 by enzyme-linked immunosorbent assay. A reduction of 42.9% was achieved based on the median AFB1 levels at baseline and after hand sorting (clean groundnuts), whereas an alternative estimate, based on the total AFB1 in moldy and clean groundnuts, indicated a reduction of 96.7%, with a loss of only 2% of the groundnuts. By roasting the already clean sorted groundnuts, the AFB1 reduction achieved (based on median levels) was 39.3%. This educational intervention on how to identify and remove moldy groundnuts was simple and effective in reducing AFB1 contamination.

ABSTRACT

Child undernutrition, a form of malnutrition, is a major public health burden in developing countries. Supplementation interventions targeting the major micronutrient deficiencies have only reduced the burden of child undernutrition to a certain extent, indicating that there are other underlying determinants that need to be addressed. Aflatoxin exposure, which is also highly prevalent in developing countries, may be considered an aggravating factor for child undernutrition. Increasing evidence suggests that aflatoxin exposure can occur in any stage of life, including in utero through a trans-placental pathway and in early childhood (through contaminated weaning food and family food). Early life exposure to aflatoxin is associated with adverse effects on low birth weight, stunting, immune suppression, and the liver function damage. The mechanisms underlying impaired growth and aflatoxin exposure are still unclear but intestinal function damage, reduced immune function, and alteration in the insulin-like growth factor axis caused by the liver damage are the suggested hypotheses. Given the fact that both aflatoxin and child undernutrition are common in sub-Saharan Africa, effective interventions aimed at reducing undernutrition cannot be satisfactorily achieved until the interactive relationship between aflatoxin and child undernutrition is clearly understood, and an aflatoxin mitigation strategy takes effect in those vulnerable mothers and children.
