Dietary Interventions to Treat Type 2 Diabetes in Adults with a Goal of Remission: An Expert Consensus Statement from the American College of Lifestyle Medicine

Objective

The objective of this Expert Consensus Statement is to assist clinicians in achieving remission of type 2 diabetes (T2D) in adults using diet as a primary intervention. Evidence-informed statements agreed upon by a multi-disciplinary panel of expert healthcare professionals were used.

Methods

Panel members with expertise in diabetes treatment, research, and remission followed an established methodology for developing consensus statements using a modified Delphi process. A search strategist systematically reviewed the literature, and the best available evidence was used to compose statements regarding dietary interventions in adults 18 years and older diagnosed with T2D. Topics with significant practice variation and those that would result in remission of T2D were prioritized. Using an iterative, online process, panel members expressed levels of agreement with the statements, resulting in classification as consensus, near-consensus, or non-consensus based on mean responses and the number of outliers.

Results

The expert panel identified 131 candidate consensus statements that focused on addressing the following high-yield topics: (1) definitions and basic concepts; (2) diet and remission of T2D; (3) dietary specifics and types of diets; (4) adjuvant and alternative interventions; (5) support, monitoring, and adherence to therapy; (6) weight loss; and (7) payment and policy. After 4 iterations of the Delphi survey and removal of duplicative statements, 69 statements met the criteria for consensus, 5 were designated as near consensus, and 60 were designated as no consensus. In addition, the consensus was reached on the following key issues: (a) Remission of T2D should be defined as HbA1c <6.5% for at least 3 months with no surgery, devices, or active pharmacologic therapy for the specific purpose of lowering blood glucose; (b) diet as a primary intervention for T2D can achieve remission in many adults with T2D and is related to the intensity of the intervention; and (c) diet as a primary intervention for T2D is most effective in achieving remission when emphasizing whole, plant-based foods with minimal consumption of meat and other animal products. Many additional statements that achieved consensus are highlighted in a tabular presentation in the manuscript and elaborated upon in the discussion section.

Conclusion

Expert consensus was achieved for 69 statements pertaining to diet and remission of T2D, dietary specifics and types of diets, adjuvant and alternative interventions, support, monitoring, adherence to therapy, weight loss, and payment and policy. Clinicians can use these statements to improve quality of care, inform policy and protocols, and identify areas of uncertainty.

A Qualitative Study: Perceived Barriers and Facilitators to Nutrition Standard Adherence by In-home Childcare Providers

BACKGROUND

The Child and Adult Care Food Program (CACFP) nutrition standards may present food purchasing, preparation, and feeding challenges for caregivers of young children.

OBJECTIVE

To elucidate perceived barriers and facilitators faced by in-home childcare providers to following the CACFP food and beverage nutrition standards.

DESIGN

Virtual, semistructured individual interviews elicited perceptions from a cross section of low-income, in-home childcare providers in Michigan.

PARTICIPANTS/SETTINGS

Twenty childcare providers of various races, ethnicity, urban and rural residence, and licensure status.

ANALYSIS

Thematic coding analysis with NVivo (ver12.0) to organize and interpret data.

RESULTS

Four primary barriers to adhering to the CACFP nutrition standards emerged including (1) noncompliant food preferences of children and providers; (2) higher cost and lower availability of CACFP-approved items; (3) celebrations and food rewards; (4) excessive time and effort needed to prepare foods and beverages, especially with dietary restrictions for some children. Ten perceived facilitators included (1) using nutrition education available through community organizations; (2) finding convenient and easy ways to prepare foods and beverages; (3) using CACFP and Special Supplemental Nutrition Program for Women, Infants, and Children guidelines and funding; (4) increasing variety of foods and beverages by using a menu or recalling items recently served; (5) modeling eating healthful foods and encouraging sampling of new foods and beverages; (6) mixing preferred foods/beverages with less preferred; (7) using nutrition information available from social media and from peers; (8) allowing children to choose foods and beverages; (9) serving the same eligible food and beverages to all children; and (10) provider concern about impact of foods and beverages on children's health and behavior.

CONCLUSIONS

Results from this study can inform nutrition education from community organizations that occurs in tandem with CACFP sponsor organizations. In addition, they can be utilized to address state-level licensure regulations and quality improvement rating systems that include nutrition standards childcare providers are encouraged or required to follow.

Reliability of the Block Kid's Food Frequency Questionnaire translated to Arabic and adapted for Kuwaiti children

OBJECTIVES

Little is known about the nutrient intakes of Kuwaiti children; this is partly due to a lack of culture-specific dietary assessment instruments to estimate the usual food and nutrient intake of Arab children. The aim of this study was to describe the methodology used in translating the 2004 Block Kid's Food Frequency Questionnaire (Block FFQ) to Arabic using adapted food choices commonly consumed by Kuwaiti children, and to evaluate the reliability of the FFQ in a population of fifth-grade Kuwaiti children.

METHODS

The 2004 Block FFQ was translated from English to Arabic, and food options were replaced with culturally appropriate foods. The modified FFQ was administered to 367 male and female Kuwaiti fifth graders (10.4 ± 0.4 y of age; 53% girls). The FFQ was retested 1 wk later in 26 male students, and 4 wk later in 32 female students. Intraclass correlations (ICC) assessed the reliability between the participants' first and second FFQs for food groups, macronutrients, and five key micronutrients.

RESULTS

The combined analysis of boys and girls indicated a moderate reliability for food groups (ICC, 0.68; 95% confidence interval [CI]; 0.52-0.80) and micronutrients (ICC, 0.54; 95% CI, 0.29-0.72), but was poor for macronutrients (ICC, 0.43; 95% CI, 0.21-0.62).

CONCLUSIONS

The modified FFQ is a modestly reliable instrument for measuring usual dietary intake in Kuwaiti children. The ICC was higher in boys than in girls, probably due to the disparity in the FFQ retest time.

Promoting Healthy Eating and Regular Physical Activity in Low-Income Families Through Family-Centered Programs: Implications for Practice

Research concerning children who are overweight has historically focused on providing services to the affected individuals, and limited attention has been paid to their families. Further, childhood obesity prevention and clinical programs continue to be impacted by contextual factors that increase the likelihood of attrition when targeting underserved populations. This paper provides data with relevance for interventions aimed at promoting healthy eating and regular physical activity with low-income families. Participants in a childhood obesity exploratory study provided recommendations to improve programs by reflecting on specific family and contextual issues related to children who are overweight and obese. Following a thematic analysis approach, we conducted semi-structured interviews with 16 low-income, single, female parents. All participants had, at the time of the interview, at least one overweight or obese child between the ages of 3 and 8. We report the critical role of context in the etiology and challenges of childhood obesity among disadvantaged populations. Findings also highlight the need for interventions to be culturally relevant and sensitive and to create opportunities to address and discuss participant experiences of discrimination, cultural factors, and family of origin influences. Interventions that do not address these contextual factors run the risk of being unsuccessful. Our findings are important for mental and public health professionals who are interested in the direct provision of services using a combination of social determinants of systemic perspectives.

Dietary Association with Glycemic Status Among Adults Clinically Diagnosed with Type 2 Diabetes in Malawi

We elucidated diet and its association with glycemic status among adults clinically diagnosed with type 2 diabetes mellitus (T2DM) through across-sectional study in Malawi. Glycosylated hemoglobin (A1C) and dietary intakes were assessed. Consumption of cereals, roots, and tubers and sweet, sugary food, including sweetened beverages, was significantly higher among participants with A1C≥8%. Fruit and vegetable intake were disproportionately low overall. Consuming adiet high in carbohydrates (OR: 1.167; CI = 1.107-1.231; p < .001) and having <3 meals/day (OR: 2.680; CI = 1.445-4.970; p = .002) were both associated with A1C≥8%. Therefore, dietary interventions for T2DM focusing on carbohydrate counting, total dietary quality, and meal planning are needed in Malawi.

Perceived barriers and facilitators to diet and physical activity among adults diagnosed with type 2 diabetes in Malawi

Diet and physical activity are crucial to Type 2 diabetes mellitus (T2DM) self-management. However, socio-environmental, and cultural factors can impede lifestyle behaviours, and hence T2DM management. This study aimed to identify barriers, facilitators and support for diet and physical activity among adults with T2DM in Malawi selected from a larger clinical assessment study, conducted in urban and semi-urban public hospitals. Four focus group discussions were conducted, and audio-recorded, transcribed verbatim, coded, then organised and analysed using thematic analysis. Emergent themes included: family, friends, and health worker ties that facilitated both diet and physical activity as socio-support systems. Diabetes peer groups occurred more often in urban than semi-urban areas. Dietary barriers to self-management of T2DM included: cost and access to food; lack of knowledge on what and how much to eat; challenges of separate preparation and purchase of food; dilemmas of what to eat during functions and travel; and conflicting dietary information from different sources. Comorbidities and fear of public ridicule were key perceived barriers to participants being physically active. Therefore, socio-environmental factors should be considered by nutritionists, dietitians, and health workers when developing and providing nutrition and physical activity education to adults with T2DM in Malawi.

Non-Dietary Factors Associated with Glycemic Status among Adults Diagnosed with Type 2 Diabetes Mellitus in Malawi

We assessed glycemic status and associations with socio-demographic, biomedical, anthropometric, and physical activity (PA) levels among adults with type 2 diabetes mellitus (T2DM) (n = 428; urban n = 288; semi-urban n = 140) using a cross-sectional study. Multivariate linear regression was used to determine factors associated with glycosylated hemoglobin (A1C) . A1C was clinically elevated ≥8% for 60.3% of the participants. Overall, age and PA levels showed a negative association with A1C, and positively with underweight status, duration of diabetes, and participants' view of fluctuating/unstable blood glucose and blood glucose not improved compared to first diagnosed. A significant negative association with A1C was shown with PA levels and additional blood glucose monitoring (BGM) beyond that received at the public clinic in the urban area. Whilst, in the semi-urban area, there was a significant positive association with A1C with regards to duration of diabetes and insulin regimen. Determinants of A1C in this target group are multifactorial, therefore, interventions aiming to improve diabetes clinical outcomes are needed to reduce the likelihood of serious ramifications. Additionally, a team approach from healthcare professionals is needed in conjunction with active patient engagement as well as the development of more comprehensive diabetes care guidelines and policies.

Risk and Protective Factors Associated with Childhood Obesity in a Sample of Low-Income, Single Female, Parent/Guardian Households: Implications for Family Therapists

The United States is in the midst of a childhood obesity epidemic that disproportionately impacts underserved and diverse populations. In this study, in-depth qualitative interviews were conducted with 16 low-income, single, female, parent/guardians of an overweight or obese 3- to 8-year-old from socioeconomically disadvantaged backgrounds. Following the tenets of the thematic analysis approach, interviews focused on identifying risk and protective factors influencing parental and child health behaviors associated with child weight status. Results from the interviews are organized according to the Socioecological Framework to help identify risk and protective factors at various system levels. Findings from this investigation have relevance for family therapists as they can inform clinical and advocacy-focused interventions with disadvantaged families affected by childhood obesity.

Participant experiences in a paraprofessional-led weight management program for children and families

Background:

Pediatric obesity is a serious and widespread medical condition that is increasing in the United States. Unfortunately, family-based programming to address the disorder fails to successfully reach and engage many children, particularly in low-income communities. To provide more affordable, accessible, and scalable programming options, researchers partnered with pediatricians and the Cooperative Extension Service (Extension) in a Midwestern state to develop a collaborative intervention. Partnering pediatricians referred children and families to a weight management program delivered by a trained Extension paraprofessional. The current study describes family experiences with the program.

Methods:

Researchers conducted a focus group or family interview with 13 program completers to elicit program perceptions, experiences with paraprofessionals, and motivators to continue. The focus group and family interviews were audio recorded and transcribed verbatim for textual analysis. Using thematic analysis, researchers examined patterns across transcripts and formulated emerging themes.

Results:

Key themes that emerged included (1) nutrition guidance, (2) interaction, (3) child influence, and (4) family engagement. Families viewed paraprofessionals as compassionate and competent educators who were instrumental in helping families modify health-related behaviors.

Conclusions:

Results of the current study are important to efforts focused on addressing childhood obesity, particularly in underserved communities where access to healthcare services is limited.

African American Women's Perceptions on Access to Food and Water in Flint, Michigan

OBJECTIVE

To explore the perceptions of food access by African American women in Flint, MI.

METHODS

Using womanist theory, in which African American women's experiential knowledge centered the analysis, 8 focus groups were conducted during fall/spring, 2014-2015. Seventeen mothers aged 21-50 years with children aged <18 years and 13 women aged >60 years comprised the groups.

RESULTS

The high cost of water, poor availability of healthy foods in inner-city stores, and limited transportation were barriers to accessing healthy food. Conversely, receiving food from food giveaways, friends, and family, as well as access to transportation facilitated food access. These women also reported discriminatory experiences and diet-related health concerns. Participants were keenly aware of available free community resources and gender, racial, and income barriers to accessing them.

CONCLUSION AND IMPLICATIONS

Understanding these barriers and facilitators provides information to aid local food policy assistance decisions and inform community-based interventions, especially given the lead contamination of water and the purported importance of a healthy diet to sequester lead.

Effects of a High Protein Food Supplement on Physical Activity, Motor Performance and Health Related Quality of Life of HIV Infected Botswana Children on Anti-Retroviral Therapy (ART)

Objective

Despite existing evidence about the benefits of nutrition, physical activity (PA) and sport to the overall health and wellbeing of children, knowledge gaps remain on this relationship in children living with chronic conditions like HIV/AIDS. Such knowledge should inform context specific programs that could enhance the quality of life of children. The purpose of this study was to examine the effects of integrating a nutrition intervention (culturally tailored food supplement) into antiretroviral therapy (ART) on psychosocial outcomes and physical activity among HIV-positive children in Botswana.

Method

201 HIV-positive children (6–15 years; M = 9.44, SD = 2.40) were recruited and randomly assigned (stratified by age and gender) to two groups. The intervention group (n = 97) received a high protein (bean-sorghum plus micronutrients) food supplement, while the control group (n = 104) received a sorghum plus micronutrients supplement. Participants were followed over 12 months. Anthropometric measures, PA, motor performance, and health related quality of life (HRQL) were collected at baseline, 6 and 12 months.

Results

Mixed repeated-measures ANOVA revealed a significant time effect of the food supplement on target variables except body fat percentage, speed, and school functioning. Time × treatment interaction was found for physical functioning, psychosocial functioning and total quality of life score. Scores on physical functioning and total of quality life in the intervention group significantly increased from baseline to 6 months compared with the control group (p = 0.015).

Conclusion

A combination of ART and nutritional intervention had a positive effect on physical functioning and total quality of life of HIV-positive children in this study. There were also improvements to physical activity and motor performance tests over time. More research is needed on long term effects of nutrition and PA interventions on HRQL in children living with HIV.

Acculturation and Self-Management Perceptions Among Mexican American Adults With Type 2 Diabetes

Because type 2 diabetes (T2DM) is disproportionately high among Mexican Americans in the United States, this study examined how acculturation influences T2DM self-management, a critical component for disease outcome. Qualitative interviews of 24 low-income Mexican American patients with T2DM were matched to their biomedical and dietary data and degree of acculturation. Greater acculturation to the United States was associated with less favorable diabetes control, fiber density, leisure-time physical activity, and more physical disability. Health care professionals can improve their cultural competence by learning culturally appropriate foods and fostering a warm, caring manner with Mexican Americans to enhance their sense of well-being and compliance with T2DM recommendations.

Assessing attentional prioritization of front-of-pack nutrition labels using change detection

We used a change detection method to evaluate attentional prioritization of nutrition information that appears in the traditional "Nutrition Facts Panel" and in front-of-pack nutrition labels. Results provide compelling evidence that front-of-pack labels attract attention more readily than the Nutrition Facts Panel, even when participants are not specifically tasked with searching for nutrition information. Further, color-coding the relative nutritional value of key nutrients within the front-of-pack label resulted in increased attentional prioritization of nutrition information, but coding using facial icons did not significantly increase attention to the label. Finally, the general pattern of attentional prioritization across front-of-pack designs was consistent across a diverse sample of participants. Our results indicate that color-coded, front-of-pack nutrition labels increase attention to the nutrition information of packaged food, a finding that has implications for current policy discussions regarding labeling change.

Validity of prepregnancy weight status estimated from self-reported height and weight

The Institute of Medicine's gestational weight gain guidelines are intended to reduce pregnancy complications, poor birth outcomes and excessive postpartum weight retention. The specific weight gain guidelines vary by prepregnancy weight status. We evaluated the validity of prepregnancy weight status (underweight, normal weight, overweight and obesity) classified from self-reported prepregnancy height and weight in reference to those from measured data during the first trimester of pregnancy and imputed data for both pregnant and age-matched non-pregnant women included in the National Health and Nutrition Examination Survey 2003-2006. Self-reported prepregnancy weight status was validated by two ideal references: imputed data with the number of imputations as 10 (n = 5,040) using the data of age-matched non-pregnant women who had both self-reported and measured data, and weight status based on height and weight measured during the first trimester (n = 95). Mean differences, Pearson's correlations (r), and Kappa statistics (κ) were used to examine the strength of agreement between self-reported data and the two reference measures. Mean (standard error of the mean) differences between self-reported versus imputed prepregnancy weight was -1.7 (0.1) kg with an r = 0.98 (p < 0.001), and κ = 0.78 which indicate substantial agreement for the 504 pregnant women. Mean (SEM) differences between self-reported prepregnancy weight versus measured weight in the first trimester was -2.3 (0.7) kg with r = 0.98 (p < 0.001), and κ = 0.76, which also showed substantial agreements in 95 pregnant women. Prepregnancy weight status classified based on self-reported prepregnancy height and weight was valid.

Social and health care provider support in diabetes self-management

OBJECTIVE

To qualitatively determine social and health care provider support in diabetes self-management of Asian Indians in the United States.

METHODS

Thirty Asian Indian adults with type 2 diabetes in either acceptable (AC) (HbA1c<7%) or unacceptable (UC) (HbA1c≥7%) glycemic control were interviewed. Emergent themes were analyzed using the constant comparison method.

RESULTS

Support from social networks and health care providers was more evident in the AC versus the UC group. UC participants tended to rely more on health-care provider guidance and communication.

CONCLUSION

Involvement of a patient's social networks might be an important part of patient-tailored interventions targeting this population.

Mealtime television viewing and dietary quality in low-income African American and Caucasian mother-toddler dyads

To examine maternal demographic characteristics and depressive symptoms as predictors of TV viewing during mealtimes, and to investigate how mealtime TV viewing predicts mothers' and toddlers' food consumption. A prospective, cross-sectional survey design was employed with 199 African American and 200 Caucasian, low-income, mother-toddler dyads enrolled in eight Early Head Start programs in a Midwestern state. Mothers completed the Toddler-Parent Mealtime Behavior Questionnaire to assess toddler mealtime behavior. Data were analyzed using a three-step multiple regression: (a) step one was to determine what characteristics predicted family TV viewing during mealtime; (b) step two was to determine whether TV viewing during mealtime predicted maternal food consumption, and (c) step three was to determine whether TV viewing during mealtime predicted toddler food consumption. Direct and indirect effects of TV watching were explored via path models. Maternal race, education, and depressive symptoms predicted 8% of the variance in TV viewing during mealtime (P < or = 0.001). African American mothers and mothers who had fewer years of schooling and exhibited more depressive symptoms tended to watch more TV during mealtime. More TV viewing during mealtime predicted mothers' intake of 'more' unhealthy foods. Mothers' food consumption was the single best predictor of toddlers' food consumption, while TV viewing during mealtime had an indirect effect through mothers' TV viewing. TV viewing practices affect mothers' food consumption and mealtime behaviors; this, in turn, impacts toddlers' food consumption. Practical interventions are needed to positively influence the nutritional habits of lower-income mothers. Reducing mothers' "unhealthy" food consumption while watching TV may offer one effective strategy.

Healthy Kids, Healthy Families: A Collaborative Program to Address Childhood Overweight

Healthy Kids, Healthy Families is a program of outreach and research that has been developed to address treatment and prevention of the childhood obesity epidemic through a family-centered, multidisciplinary approach. The American Dietetic Association recommends community-based and environmental interventions as the most feasible methods to support healthful lifestyles for the greatest numbers of children and families (Ritchie, Crawford, Hoelscher, & Sothern, 2006). Healthy Kids, Healthy Families was developed as an innovative, collaborative program to help children and families maintain healthy weight, through impacting the systemic medical and psychosocial aspects of overweight in children. The program involves in-home, family-based intervention followed by multi-family group education and community outreach.

Nutrition students improve attitudes after a guided experiential assignment with older adults

OBJECTIVE

Develop, implement, and evaluate an intervention (a guided experiential assignment) to improve nutrition students' attitudes toward working with older adults.

DESIGN

A quasi-experimental design with an additional qualitative component (mixed methods).

SETTING

A North Central land-grant university.

PARTICIPANTS

100 college students from an upper-level community nutrition course.

INTERVENTION

Students were randomly assigned to conduct a guided experiential assignment (dietary behavior change project) working with either an older adult (intervention, n = 52) or a younger adult (comparison, n = 48). Each student conducted 3 client interviews and completed a project report by responding to reflective questions about changes in beliefs, values, and self-efficacy in working with older adults.

MAIN OUTCOME

The primary outcome was attitudes toward older adults as changed in reference to students' beliefs, values, and self-efficacy in working with other adults. Additional outcomes were knowledge of aging and interest in working with older adults.

ANALYSIS

General linear model multivariate/univariate analysis and content analysis were conducted on the quantitative and qualitative data, respectively.

RESULTS

The intervention group had significantly increased scores on attitudes toward older adults relative to the comparison group. This finding appeared as a result of changes in beliefs about older adults and the increased value and self-efficacy in working with this group by most students in the intervention group.

CONCLUSION AND IMPLICATIONS

Completion of a guided experiential assignment with older adults in the community was an effective method to improve students' attitudes. Used in the curriculum for nutrition students, this technique might help to improve both attitudes toward and self-efficacy in working with older adults.

Previous experience with older adults positively affects nutrition students' attitudes toward this age group

OBJECTIVES

To explore: (1) dietetic and nutritional science students' attitudes toward working with older adults and the factors affecting those attitudes; (2) the differences in attitudes between students who preferred to work with older adults and those who did not; (3) factors affecting self-efficacy to work with them; and (4) factors influencing current preference to work with older adults.

DESIGN

Triangulated qualitative research methods (focus groups and in-depth interviews).

SETTING

Department of Food Science and Human Nutrition at a land grant university in the north central United States.

PARTICIPANTS

Upper-level dietetics and nutritional sciences students (N=27), half of whom preferred to work with older adults and half who did not.

MAIN OUTCOMES

Attitudes and preference for working with older adults and influencing factors.

ANALYSIS

Transcripts from audiotapes and field notes were analyzed using open and axial coding methods.

RESULTS

Students who preferred working with older adults had more positive attitudes toward working with older adults compared to those who did not. Previous experience with older adults was strongly associated with comfort level, self-efficacy to work with them, attitudes toward this age group, and preference for working with them.

IMPLICATIONS FOR RESEARCH AND PRACTICE

Direct and positive interaction with older adults is likely a key intervention to improving students' attitudes toward working with this age group.
