RESUMO
Background: Limited research exists on the specific approaches and behavior change techniques (BCT) used in nutrition-sensitive agriculture (NSA) programs and their effects on diet diversity. Objectives: We aimed to describe nutrition-related social behavior change (SBC) in the context of NSA and quantify the effectiveness of different SBC components of NSA programs in improving diet diversity. Methods: We searched PubMed, Embase, Web of Science, the International Food Policy and Research Institute repository, and Agricola for articles published between 2000 and 2023. We identified the agricultural activities each project used as a pathway to improved nutrition (ag-nutrition pathways), identified SBC approaches used by each project, and coded BCTs using validated coding protocols. Effectiveness ratios (ERs) were calculated to assess pathways, approaches, and BCTs in relation to dietary diversity outcomes (minimum diet diversity for children, child dietary diversity score, and women's dietary diversity). Results: Of 65 included NSA interventions, the most used agriculture-to-nutrition pathways included 1) agricultural production for home consumption (n = 61); 2) women's empowerment (n = 36); and 3) agricultural income (n = 37) pathways. The most used SBC approaches were interpersonal communication (IPC, n = 59) and community-based approaches (n = 53). Frequently used BCTs included "instructions on how to perform the behavior" (n = 65), "social support (unspecified)" (n = 43), and using a "credible source" (n = 43). The increased production for the home consumption pathway, IPC approach, and the BCT "behavioral practice" had high ERs for diet diversity outcomes. Conclusions: Although the agricultural production for home consumption pathway to improved nutrition had the highest ERs for diet diversity, other pathways, such as income generation and reducing wastage, hold promise and require additional investigation. The most commonly applied BCTs focused on information dissemination; however, participatory BCTs related to behavioral demonstration, and behavioral practice had higher ERs. Findings indicate a need to test less frequently utilized SBC components to determine effectiveness.This trial was registered at PROSPERO (=https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=179016) as CRD42020179016.
RESUMO
Background: Proper nutrition is a crucial factor in preventing osteoporosis, a significant pathological cause linked to skeletal weakness; this study investigated the relationship between dietary diversity score and food group diversity score with osteoporosis in postmenopausal women. Methods: This case-control study was conducted on 378 menopausal women aged 45-85 in Tehran, Iran. The age-matching method to control the confounding effect of age was used. The method of dual-energy X-ray absorptiometry (DXA) was used for assessing the bone mineral density of lumbar vertebrae and femoral neck. The bone mass status was evaluated with WHO criteria. All subjects were divided into the osteoporosis group and the non-osteoporosis group according to their T-score. A convenience sampling method was utilized to select the participants, which included two groups: case (n = 189) and control (n = 189). Data was collected using demographic and anthropometric information questionnaires, a valid 147 item food frequency questionnaire, and a physical activity questionnaire. Statistical analyses were conducted using SPSS-26, and p-values less than 0.05 were deemed to be statistically significant. Results: The results indicated significant differences in weight, body mass index, physical activity, smoking, and alcohol use between the two groups. The mean ± standard deviation of dietary diversity score (DDS) was lower in participants with osteoporosis (case) (3.31 ± 1.26) than in control (4.64 ± 1.33) (p < 0.001). The mean ± standard deviation of diversity score of cereals, fruits, and vegetables in the osteoporosis group (respectively: 0.71 ± 0.21, 0.94 ± 0.76, and 0.45 ± 0.44) was less than the control group (respectively: 0.80 ± 0.21, 1.64 ± 0.55 and 0.87 ± 0.42) (p < 0.001). After adjusting the confounding variables, the risk of osteoporosis had an inverse relationship with the diversity score of vegetable (OR = 0.16; 95%CI: 0.07-0.35), bread and cereal (OR = 0.21; 95% CI: 0.05-0.87) and fruit (OR = 0.35; 95%CI: 0.22-0.56) (p < 0.05). Nevertheless, no discernible correlation was seen between the tertiles of DDS, dairy and meat diversity score, and osteoporosis. Conclusion: We found a correlation between the diversity score of fruits, vegetables, and grains and osteoporosis. However, there is no significant correlation between the DDS triads and the diversity score of dairy products and meats with osteoporosis.

Introduction: Variety and adequacy of intake of food are required to meet the nutritional needs of the children. Due to poverty/illiteracy, poor families depend on a single food group that is, cereals. Due to the pandemic also, the nutrition of the growing children is affected. Objective: To know the effect of quantity and quality of diet on the nutritional status of under-five children. Methodology: This study had 270 children aged between 1 and 4 years registered at Anganwadi as study participants. Information on sociodemographic variables, quantity of calories and proteins consumed, quality of diet, and anthropometry of children was collected. Percentages and paired t-tests were used to find the difference between nutritional status and diet at different intervals, which was found to be statistically significant (P < 0.05). Results: In our study, we found that as the quantity and quality of diet improved nutritional status, especially weight for age, body mass index (BMI) for age Z score also improved. There was a significant difference between calories consumed at the baseline, 6 months and 1 year with P < 0.05. Protein intake was significant between baseline and six months with P < 0.005. Conclusion: Our study found a high percentage of undernutrition and wasting in the under-five population when diet was not sufficient in quality and quantity. As the quality and quantity of diet improved nutritional status also improved.
RESUMO
BACKGROUND: Adoption of allergen avoidance diets may increase the risk of nutritional deficiencies and affect growth in children with food allergy (FA). How these dietary restrictions have an impact on diet diversity, a health-promoting eating behavior, remains unclear. OBJECTIVE: To evaluate diet diversity, dietary intake, and weight status of children with FA. DESIGN: Observational study. PARTICIPANTS/SETTING: One hundred children with immunoglobulin E (IgE)-mediated milk, egg, or nut FA or multiple FAs and 60 children with perennial respiratory allergies (RA) matched as controls, aged 3 to 18 years, were consecutively recruited into the study. MAIN OUTCOME MEASURES: Dietary intake and diet diversity (number of different foods consumed/day) were assessed through 4 24-hour recalls. Weight status (underweight, healthy weight, overweight, or obesity) was also evaluated. STATISTICAL ANALYSES PERFORMED: Chi-squared test and 2-sample independent t test were used to test differences between groups. Adjustment for sex, age, and energy intake was made using linear regression. RESULTS: The percentage of underweight was higher in children with FA (19.6%) compared with children in the control group (5.1%). Children with FA compared with children in the control group consumed more servings of meat (1.7, 95% CI, 1.6, 1.9 vs. 1.5, 95% CI, 1.3, 1.7 servings/day [Padj = 0.031]). No difference was observed in the diet diversity between the 2 groups (11-12 different foods/day). Within the FA group, children with allergy to milk proteins had lower energy intake from protein, lower intake of calcium, lower consumption of commercially prepared sweets, and higher consumption of eggs, compared with children with nut or egg allergy, but no difference in diet diversity was observed. CONCLUSIONS: Diet diversity did not differ between children with FA and children with no FA, despite some differences in the intake from specific food groups. However, the higher percentage of underweight in children with FA suggests the need for targeted nutrition intervention as early as possible after FA diagnosis.
RESUMO
Background: Concurrent losses in biodiversity and human dietary diversity are evident in Madagascar and across many food systems globally. Wild food harvest can mitigate nutrition insecurities but may also pose species conservation concerns. Objectives: This study aimed to examine the association of wild plant and animal species consumption during hunger season with diet diversity and child growth near the Alandraza-Agnalavelo protected forest in Southwestern Madagascar. Second, we studied the conservation status of the consumed wild plants. Methods: Methods from public health nutrition (24-h recall dietary intake, anthropometry using World Health Organization [WHO] Growth Standards), ethnobotany, and forest ecology (ecologic studies of abundance, habitat preference, associated species, food chemistry assays, and species richness) were applied. Results: Malnutrition in children (n = 305) was highly prevalent: stunting (32.3%); wasting (18.8%); and low-dietary diversity (4% meeting WHO minimum dietary diversity threshold). Animal foods were consumed in small quantities, providing <10% of Dietary Reference Intakes for all limiting nutrients. Twenty-two wild plant species were consumed during hunger season, prominently tubers (Dioscoreaceae), and leafy greens (Asteraceae, Blechnaceae, Portulacaceae, and Solanaceae). Eight of the 9 target species were identified as abundant and "Least Concern," whereas Amorphophollus taurostigma was abundant and "Vulnerable." Regression modeling showed wild food consumption was associated with an increased household dietary diversity score [ß = 0.29 (0.06 standard error); P < 0.001], and total wild animal foods positively correlated with height-for-age Z score [ß = 0.14 (0.07 standard error); P = 0.04]. Conclusions: Wild plant and animal foods may be an important element of food systems to support human nutrition while maintaining ecosystem viability.
RESUMO
The purpose of the current study was to critically assess the gaps in the existing methodologies of dietary data collection for diet diversity indicators. The study proposed the importance of smartphone application to overcome the drawbacks. The review paper identified and assessed the conventional methodologies used in diet diversity indicators including Minimum Dietary Diversity for Women (MDD-W), Minimum Dietary Diversity of Infant and Young Child Feeding Practices (IYCF-MDD), and Household Dietary Diversity Score (HDDS). The 80 research studies from 38 countries were critically assessed on the basis of their research aim, study design, target audience, dietary data collection methodology, sample size, dietary data type, dietary data collection frequency, and location point of dietary data collection. Results indicated that most studies employed interviewer-administered 24-h recall assessing the dietary diversity. The review paper concluded that smartphone application had potential to overcome the identified limitations of conventional methodologies including recall bias, social-desirability bias, interviewer training, and cost-time constraints.
RESUMO
Poor diet quality (diet diversity and animal-source food [ASF] consumption) during childhood negatively affects growth, development, behaviour and physiologic function in later life. Relatively less is known about the impact of poor diet on the growth of school-age children compared to children <5 years of age, especially in low/middle-income countries. A better understanding of delivery strategies for effective interventions to improve diet and hence growth in school-age children is needed. A 36-month longitudinal controlled impact evaluation in rural Nepal assessed the nutrition and growth of children <5 years of age in families assigned via community clusters to full package intervention (community development, training in nutrition [during pregnancy and for children <5 years] and livestock husbandry), partial package (training only) or control (no inputs). Concurrent data were collected prospectively (baseline plus additional four rounds) on school-age children (5-8 years at baseline) in these households; the present study analysed findings in the cohort of school-age children seen at all five study visits (n = 341). Diet quality improved more in the full package school-age children compared to those in partial package or control households. full package children consumed more ASF (ß +0.40 [CI 0.07,0.73], p < 0.05), more diverse diets (ß +0.93 [CI 0.55,1.31], p < 0.001) and had better head circumference z-scores (ß +0.21 [CI 0.07,0.35], p < 0.01) than control children. In conclusion, a multi-sectoral community development intervention was associated with improvements in diet and growth of school-age children in rural Nepal even though the intervention focused on the diet of children <5 years of age. The diet and growth of school-age children can be favourably influenced by community-level interventions, even indirectly.

INTRODUCTION: Food security and nutrition have been severely impacted during the COVID-19 pandemic, particularly in low- and middle-income countries (LMICs). We aimed to quantify the impacts of the pandemic on food security and diet diversity within Chilanga District in Zambia and identify target areas for high-impact social protection and safety net programs. METHODS: We conducted a cross-sectional study in Chilanga district immediately after the Omicron variant surge in February 2022. Diet quality and food security were assessed based on a household diet questionnaire and a Minimum Dietary Diversity-Women (MDD-W) score was calculated. A paired t-test was used to determine whether there was a statistically significant change in the MDD-W score and McNemar test was used to investigate the change in food security between the pre- and peri-COVID-19 period. RESULTS: Compared to the pre-COVID-19 period, there were increases in food prices across the board in the peri-COVID-19 period and decreased consumption of key food categories including legumes, dairy and vitamin A rich foods. Despite high rates of food insecurity, only 6.6% of surveyed households received any cash or in-kind assistance from a government agency, non-profit, or other organization in the post-COVID-19 period. CONCLUSION: The COVID-19 pandemic had significant impacts on food security and dietary diversity in Chilanga district. This is particularly relevant in the low-income communities that we surveyed, which had pre-existing challenges with food security. Additional resources must be invested in Chilanga District and similarly affected areas to address this gap in access to food and promote national equity. Trial Registration N/A.

OBJECTIVE: In South Asia, while women make substantial economic contributions through their participation in agricultural sector, these contributions are undercounted as most of their work is underpaid or unpaid. This paper examines how mothers allocate their time to productive and reproductive activities and its association with a household's ability to achieve high household diet diversity score. DESIGN: The analysis uses data on household consumption and expenditure including food during the kharif (June to October) season (seeds are sown) and a modular time-use survey. SETTING: Two districts of rural Bihar, India. PARTICIPANTS: Mothers with children less than 5 years of age and supported by the head of the household from 2026 households. RESULTS: The estimates indicate that the high household diet diversity (High HDDS ≥ 10) is associated with greater time spent in reproductive activities by all women (OR = 1·12, 95 % CI: 1·06, 1·18). However, with increasing time spent in productive activities by the women the odds of achieving 'High HDDS' reduced (OR = 0·83, 95 % CI: 0·77, 0·89) in adjusted logistic regression analysis. CONCLUSION: The findings highlight propensity to achieve 'High HDDS' in Bihar increased with mothers allocating time towards reproductive activities, while it had an opposing effect with mothers allocating time on productive activities. Our study highlights that the policies that encourage women's participation in agriculture or livestock should acknowledge the unpaid nature of some of the productive activities and design programs to improve economic agency of women to actuate the true potential of agriculture-nutrition pathways.

Pollinators face many stressors, including reduced floral diversity. A low-diversity diet can impair organisms' ability to cope with additional stressors, such as pathogens, by altering the gut microbiome and/or immune function, but these effects are understudied for most pollinators. We investigated the impact of pollen diet diversity on two ecologically and economically important generalist pollinators, the social bumble bee (Bombus impatiens) and the solitary alfalfa leafcutter bee (Megachile rotundata). We experimentally tested the effect of one-, two-, or three-species pollen diets on gut bacterial communities in both species, and the melanization immune response in B. impatiens. Pollen diets included dandelion (Taraxacum officinale), staghorn sumac (Rhus typhina), and hawthorn (Crataegus sp.) alone, each pair-wise combination, or a mix of all three species. We fed bees their diet for 7 days and then dissected out guts and sequenced 16S rRNA gene amplicons to characterize gut bacterial communities. To assess melanization in B. impatiens, we inserted microfilament implants into the bee abdomen and measured melanin deposition on the implant. We found that pollen diet did not influence gut bacterial communities in M. rotundata. In B. impatiens, pollen diet composition, but not diversity, affected gut bacterial richness in older, but not newly-emerged bees. Pollen diet did not affect the melanization response in B. impatiens. Our results suggest that even a monofloral, low-quality pollen diet such as dandelion can support diverse gut bacterial communities in captive-reared adults of these bee species. These findings shed light on the effects of reduced diet diversity on bee health.

(1) Background: Sub-optimal feeding practices and dietary intakes in childhood are associated with poor health outcomes in adulthood. This mixed methods study aims to profile feeding practices, parent perceptions, and dietary diversity in a sample of children aged 0-5 years (n = 29) from Western Sydney, Australia. (2) Methods: In 2019, semi-structured interviews were conducted with parents, exploring their child's feeding practices. An online quantitative survey was used to assess children's feeding history. Nutrient intakes and dietary diversity scores were assessed using an online 24-h dietary recall. Quantitative data were analysed using descriptive statistics and one-way ANOVA, while qualitative data were analysed using inductive thematic analysis. (3) Results: The analysis showed that 27.6% of children were exclusively breastfed until 6 months of age and that 62.1% of children were introduced to solids before 6 months. Over 60% of children achieved minimum dietary diversity. The thematic analysis identified four themes, including mothers' feeding choices, mothers' perceptions of their children's diet, influences on feeding choices, and mothers' personal experiences. (4) Conclusions: The feeding history of over half the children in this sample indicated non-compliance with Australian and WHO infant feeding guidelines. The thematic analysis revealed various possible influences on parent feeding choices that can be used to inform targeted support.

BACKGROUND: Sarcopenia is a clinical issue in older adults that leads to serious adverse health outcomes, including disability. The present study investigated whether dietary diversity affects the incidence of disability in older adults with sarcopenia. METHOD: Participants were 759 Japanese older adults with sarcopenia (mean age 77.2 ± 6.0 years; 44.4 % men) who were aged ≥65 years at the time of the examination. Sarcopenia was diagnosed according to the recommendations of the European Working Group on Sarcopenia in Older People 2. Dietary diversity was assessed using a diet variety score. This diet variety score assessed the one-week consumption frequency of ten food groups, according to the following responses: "eat almost every day" (1 point), or "not eaten almost daily" (0 points). Older adults with a diet variety score of 3 or more points were defined as having high dietary diversity. Incident disability was certified by long-term care insurance (mean follow-up duration 32 months). RESULTS: The cumulative disability incidence rates in the older adults with low dietary diversity and high dietary diversity were 23.3 % and 16.9 %, respectively. Cox proportional hazards regression analysis revealed high dietary diversity was associated with a lower risk of incident disability in older adults with sarcopenia (hazard ratio 0.66, 95 % confidence interval 0.47-0.92; p = 0.015), after adjusting for covariates. CONCLUSIONS: This longitudinal study revealed that high dietary diversity is associated with a lower risk of incident disability among sarcopenic Japanese older adults.

OBJECTIVE: To assess how well national sentinel lists of the most frequently consumed foods in each food group capture data at subnational levels to measure minimum diet diversity (MDD). DESIGN: We analysed data from seven surveys with 24-h open dietary recalls to evaluate: (1) the percentage of reported foods that were included in each sentinel food list; (2) whether these lists captured consumption of some food groups better than others and (3) differences between estimates of dietary diversity calculated from all food items mentioned in the open 24-h recall v. only food items included in the sentinel lists. SETTING: Seven subnational areas: Bangladesh (2), Benin, Colombia, Kenya, Malawi and Nepal. PARTICIPANTS: 8094 women 15-49 years; 4588 children 6-23 months. RESULTS: National sentinel food lists captured most foods reportedly consumed by women (84 %) and children (86 %). Food groups with the highest variability were 'other fruits' and 'other vegetables.' MDD calculated from the sentinel list was, on average, 6·5 (women) and 4·1 (children) percentage points lower than when calculated from open 24-h recalls, with a statistically significant difference in most subnational areas. CONCLUSION: National sentinel food lists can provide reliable data at subnational levels for most food groups, with some variability by country and sub-region. Assessing the accuracy of national sentinel food lists, especially for fruits and vegetables, before using them at the subnational level could avoid potentially underestimating dietary diversity and provide more accurate local information for programmes, policy and research.

Dietary diversity (DD) plays a crucial role in fostering high-quality diets, but its association with health outcomes, particularly body adiposity and non-communicable diseases (NCDs), is inconsistent. This may be due to a lack of a standardized method for estimating DD. Our study investigates the association between two DD indices, namely the dietary diversity score (DDS) and food variety score (FVS), and anthropometric measures, biochemical parameters, and diet quality in a large population sample from the I.Family study across research centers in eight European countries. In our cross-sectional analysis of 3035 participants, DDSs varied among countries, with a higher prevalence in the third DDS tertile among those with higher education. DDS showed a positive association with diet quality across all age groups. Higher DDS tertile individuals showed increased fiber, fruit, and vegetable intake, greater meal frequency, and lower ultra-processed food consumption. No relevant biochemical differences were observed across DDS tertiles, and a higher DDS was associated with lower overweight/obesity prevalence only in adults. No significant associations were found with FVS. Our findings emphasize the need to consider food groups for a more accurate estimation of diet quality. This aligns with studies suggesting DDS alone is not an independent risk factor for obesity in children and adolescents. Public health programs should prioritize food diversity to promote improved nutrition and overall well-being in communities.
RESUMO
Background and aims: Diversity is a key element of diet quality. The Food Variety Score (FVS) is used to assess diversity, especially in low- and middle-income countries. It sums up the number of foods consumed ignoring their nutrient content. A more suitable index should combine the number of foods consumed and their nutritional composition. We adapted the Nutritional Functional Diversity indicator (NFD), proposed by ecologists, to measure diversity in the human diet. We compared NFD and FVS evaluating subjects' distributions across quartiles of the two diversity indices. To evaluate which one reflected a higher diet quality, we estimated associations between these two diversity indices and diet quality measures, i.e., the Mediterranean Diet Score (MDS) and the Healthy Eating Index-2015 (HEI-2015). Associations were expressed by odds ratios (OR) and corresponding 95% confidence intervals (CI). Materials and methods: We used the data of controls only derived from an integrated series of hospital-based case-control cancer studies conducted in different Italian areas. The NFD identifies groups of foods based on a set of nutrients according to a cluster analysis. Some steps are required: creating a food-nutrient matrix; clustering of the Euclidean food-food distance matrix to identify groups of foods with nutritional (dis)similarities; and calculating the NFD as the ratio between the sum of branch lengths of the dendrogram belonging to the number of foods consumed by individuals (i.e., subject-specific diversity) and the sum of all branch lengths of the dendrogram (i.e., maximal diversity). Results: More than one quarter of individuals (28.4%) were differently classified within quartiles of the two diversity indices. For both indices, increasing the diversity level increased the risk for adhering to MDS (OR for NFD = 11.26; 95% CI: 7.88-16.09, and OR for FVS = 6.80; 95% CI: 4.84-9.54) and to HEI-2015 (OR for NDF = 2.86; 95% CI: 2.39-3.42, and OR for FVS = 2.72; 95% CI: 2.27-3.26). Associations were stronger for NFD. Conclusion: Our findings showed a greater ability of NFD to assess diet quality quantifying the degree of diversity.
RESUMO
Human food foraging in community forests offers extensive and expandable sources of food and high-quality nutrition that support chronic disease prevention and management and are underrepresented in US diets. Despite severe gaps in non-commercial "wild food" data, research in Syracuse, NY, identified substantial amounts of five key antioxidant phytochemicals in locally available, forageable foods with the potential to augment local dietary diversity and quality. Findings endorse the need for micro- and macro-nutrient research on an expanded range of forageable foods, community nutrition education on those foods, an expanded study on antioxidant phytochemical function, and the inclusion of forageables in the food system definition.

Diet plays a crucial role in regulating individuals' lifestyles and is closely related to health. The intake of animal-sourced foods (ASF) provides the human body with high-quality protein and various micronutrients. This study aimed to investigate whether the diversity of animal foods has a positive impact on the health-related quality of life (HRQoL) among residents. The data came from the Shaanxi baseline survey of the Northwest Chinese Regional Ethnic Cohort Study, which recruited more than 100 thousand participants aged 35 to 74 from five provinces between June 2018 and May 2019. A total of 39,997 participants in Shaanxi (mean age: 50 years; 64% women) were finally included in this current study. The animal source food diet diversity score (ASFDDS) was established based on the frequency of consuming pork, mutton, beef, poultry, seafood, eggs, pure milk, and yogurt. The physical component score (PCS) and mental component score (MCS), ranging from 0 to 100 on the 12-Item Short Form Survey (SF-12), were used to assess participants' HRQoL. Better PCS/MCS was defined as scores higher than the 90th percentile. The results showed that men had a higher intake of ASF and ASFDDS than women. After adjusting for potential confounders, compared with those who never or rarely consumed animal foods, the likelihood of having better PCS and MCS increased by 16% (OR = 1.16, 95%CI: 1.01-1.34) and 24% (OR = 1.24, 95%CI: 1.03-1.448), respectively, in men with an ASFDDS ≥ 2. In women, a 34% increase (OR = l.34, 95%CI: 116-l.54) likelihood for better PCS was observed for an ASFDDS ≥ 2, but no association was observed for MCS. Increasing each specific animal source's food intake was associated with better PCS after adjusting for all covariates. However, for MCS, positive associations were only observed in seafood consumption among men and eggs among women. Restricted cubic splines showed a substantial dose-response association between intake frequency of animal-source foods and PCS, both in men and women. The study suggests that a diverse intake of animal-sourced foods can potentially improve the HRQoL of Chinese adults.

Allergic diseases are increasing both in morbidity and mortality. Genetic, environmental, and dietary factors may all be involved in this increase. Nutrition during pregnancy, breastfeeding, and early life may play a particularly important role in preventing allergic diseases. Based on current systematic reviews, the intake of specific nutrients has failed to prevent allergic disease. Prevention strategies have shifted their focus to the overall diet which can be described using diet diversity. Infant and maternal diet diversity in pregnancy has been associated with reduced allergy outcomes in childhood. Overall, diet also seems to have a marked effect on the microbiome compared to single foods. Factors that may negate the allergy-preventative effect of overall diet diversity include the addition of emulsifiers, advanced glycation end-product content, and overuse of commercial baby foods. There is a need to perform randomized controlled trials using overall dietary intake to support international food allergy guidelines. These studies should ideally be conducted by multi-professional teams.
