Development of an index to assess adherence to the traditional Mexican diet using a modified Delphi method.

ABSTRACT:

Objective

Promoting a traditional Mexican diet (TMexD) could potentially reduce high rates of non-communicable diseases (NCD) and support food sustainability in Mexico. This study aimed to develop an index to assess adherence to the TMexD.

Design

A three-round Delphi study was conducted to examine the food groups, specific foods and food-related habits that would constitute a TMexD index. Participants selected the TMexD items using Likert scales, lists of responses, and yes/no questions. Consensus was determined using percentages of agreement, mean values and/or coefficients of variation.

Setting

Online Delphi study.

Participants

Seventeen nutrition and food experts in Mexico completed all three rounds.

Results

The resulting index (ranging from 0 to 21 points) consisted of 15 food groups, containing 102 individual foods. Food groups included in higher quantities were maize, other grains, legumes, vegetables, fruits, herbs, nuts and seeds, and tubers. Animal foods, vegetable fats and oils, homemade beverages, maize-based dishes, and plain water were also included, but in lower quantities. The food-related habits included were consuming homemade meals, socialising at meals and buying food in local markets. Consensus was reached for all index items apart from quantities of consumption of six food groups (herbs, nuts, grains, tubers, dairy and eggs).

Conclusions

Although future research could improve the measures for which consensus was not reached, the TMexD index proposed in this study potentially displays a healthy and sustainable dietary pattern and could be used to examine links between the TMexD and health outcomes in Mexican populations.

Project description:BackgroundWomen of Mexican descent are disproportionally affected by obesity, systemic inflammation, and insulin resistance (IR). Available approaches used to give scores to dietary patterns relative to dietary guidelines may not effectively capture traditional diets of Mexicans, who comprise the largest immigrant group in the United States.ObjectivesWe characterized an a priori traditional Mexican diet (MexD) score high in corn tortillas, beans, soups, Mexican mixed dishes (e.g., tamales), fruits, vegetables, full-fat milk, and Mexican cheeses and low in refined grains and added sugars and evaluated the association of the MexD score with systemic inflammation and IR in 493 postmenopausal participants in the Women's Health Initiative (WHI) who are of Mexican ethnic descent.MethodsThe MexD score was developed from the baseline (1993-1998) WHI food frequency questionnaire, which included Hispanic foods and was available in Spanish. Body mass index (BMI) was computed from baseline measured weight and height, and ethnicity was self-reported. Outcome variables were high sensitivity C-reactive protein (hsCRP), glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), and triglyceride concentrations measured at follow-up (2012-2013). Multivariable linear and logistic regression models were used to test the associations of the MexD score with systemic inflammation and IR.ResultsThe mean ± SD MexD score was 5.8 ± 2.1 (12 maximum points) and was positively associated with intakes of carbohydrates, vegetable protein, and dietary fiber and inversely associated with intakes of added sugars and total fat (P < 0.01). Women with high compared with low MexD scores, consistent with a more-traditional Mexican diet, had 23% and 15% lower serum hsCRP (P < 0.05) and insulin concentrations, respectively (P < 0.05). Baseline BMI modified these associations such that lower MexD scores were associated with higher insulin and HOMA-IR in overweight/obese women (P-interaction <0.05).ConclusionThese findings suggest that greater adherence to a traditional Mexican diet could help reduce the future risk of systemic inflammation and IR in women of Mexican descent.

Project description:ObjectivesRural-urban healthcare disparities exist globally. Various countries have used a rurality index for evaluating the disparities. Although Japan has many remote islands and rural areas, no rurality index exists. This study aimed to develop and validate a Rurality Index for Japan (RIJ) for healthcare research.DesignWe employed a modified Delphi method to determine the factors of the RIJ and assessed the validity. The study developed an Expert Panel including healthcare professionals and a patient who had expertise in rural healthcare.SettingThe panel members were recruited from across Japan including remote islands, mountain areas and heavy snow areas. The panel recruited survey participants whom the panel considered to have expertise.ParticipantsThe initial survey recruited 100 people, including rural healthcare providers, local government staff and residents.Primary outcome measuresFactors to include in the RIJ were identified by the Expert Panel and survey participants. We also conducted an exploratory factor analysis on the selected factors to determine the factor structure. Convergent validity was examined by calculating the correlation between the index for physician distribution and the RIJ. Criterion-related validity was assessed by calculating the correlation with average life expectancy.ResultsThe response rate of the final survey round was 84.8%. From the Delphi surveys, four factors were selected for the RIJ: population density, direct distance to the nearest hospital, remote islands and whether weather influences access to the nearest hospital. We employed the factor loadings as the weight of each factor. The average RIJ of every zip code was 50.5. The correlation coefficient with the index for physician distribution was -0.45 (p<0.001), and the correlation coefficients with the life expectancies of men and women were -0.35 (p<0.001) and -0.12 (p<0.001), respectively.ConclusionThis study developed the RIJ using a modified Delphi method. The index showed good validity.

Project description:BackgroundDiet quality in early childhood has a long-term impact on health outcomes. However, there are scarce dietary indexes for Chinese preschool children, and the existing indexes had limited validity and reliability. This study thus aimed to develop a dietary index for preschool children based on the Chinese Dietary Guideline and Chinese Dietary Reference Intakes and to assess their overall diet quality using the China Health and Nutrition Survey (CHNS).MethodsThe Chinese Preschooler Dietary Index (CPDI) included 11 components, covering 9 food group components and two nutrient components. The total scores of CPDI ranged from 0 to 90, with a higher score indicating greater diet quality. This study assessed the diet quality of 1742 preschoolers aged two to five years old from CHNS using the CPDI. Dietary intake data were obtained using three-day 24-h diet recalls, and sociodemographic information was also collected. Cochran-Mantel-Haensel (CMH) test was used to explore the association between demographic and CPDI total scores. The principal component analysis, correlation analysis and Cronbach's alpha were used to evaluate the relative reliability and validity of the CPDI. Finally, a stepwise multiple regression analysis was performed to explore potential influencing factors of CPDI.ResultsAmong the 1742 CHNS preschool children, more than 70% resided in rural areas and 41.2% of the sample were raised in a low-income family. The mean CPDI score of the preschoolers was 38.8 ± 12.9. Higher diet scores were correlated with higher energy and nutrient intake. Children with higher age (β = 0.93, SE = 0.26, P = 0.0003), raised in a home with higher household income (β = 3.11, SE = 0.27, P < 0.0001) or living in urban areas (β = -4.44, SE = 0.66, P < 0.0001) were associated with higher CPDI scores.ConclusionsThe CPDI is useful in evaluating the diet quality of preschool children. Based on the CPDI, the diet quality of Chinese preschoolers needs to be improved, especially in rural areas.
