The Impact of a Lifestyle Intervention on Postpartum Cardiometabolic Risk Factors Among Hispanic Women With Abnormal Glucose Tolerance During Pregnancy: Secondary Analysis of a Randomized Trial

BACKGROUND

Women with abnormal glucose tolerance during pregnancy are at risk for cardiovascular disease (CVD), with higher rates among Hispanics. However, studies on the impact of lifestyle interventions on postpartum CVD profiles are sparse.

METHODS

This is a secondary analysis of a controlled trial among a subsample of Hispanic women with abnormal glucose tolerance participating in Estudió PARTO (Project Aiming to Reduce Type twO diabetes; mean age = 28.2 y, SD: 5.8) who were randomized to a culturally modified Lifestyle intervention (n = 45) or a comparison Health and Wellness intervention (n = 55). Primary endpoints were biomarkers of cardiovascular risk (lipids, C-reactive protein, fetuin-A, and albumin-to-creatinine ratio) and insulin resistance (fasting insulin, glucose, HbA1c, homeostasis model assessment, leptin, tumor necrosis factor-alpha, and adiponectin) measured at baseline (6-wk postpartum) and 6 and 12 months.

RESULTS

In intent-to-treat analyses, there were no significant differences in changes in biomarkers of CVD risk or insulin resistance over the postpartum year. In prespecified sensitivity analyses, women adherent with the Lifestyle Intervention had more favorable improvements in insulin (intervention effect = -4.87, SE: 1.93, P = .01) and HOMA-IR (intervention effect = -1.15, SE: 0.53, P = .03) compared with the Health and Wellness arm. In pooled analyses, regardless of intervention arm, women with higher postpartum sports/exercise had greater increase in HDL-cholesterol (intervention effect = 6.99, SE: 1.72, P = .0001).

CONCLUSIONS

In this randomized controlled trial among Hispanic women with abnormal glucose tolerance, we did not observe a significant effect on postpartum biomarkers of CVD risk or insulin resistance. Women adherent to the intervention had more favorable changes in insulin and HOMA-IR.

Attitudes of women with gestational diabetes toward diet and exercise: a qualitative study

OBJECTIVE

Gestational diabetes (GDM) refers to glucose intolerance of varying severity first occurring in pregnancy. Following a diagnosis of GDM, exercise and dietary modification has a positive effect on improving glycemic control. Lifestyle changes affected in pregnancies affected by GDM have beneficial effects on long-term health if continued following birth. In addition, the psychological impact of a diagnosis of GDM should not be overlooked. Reports of maternal stress, anxiety, and fear are commonly reported issues in the literature. Support, both socially and from health care professionals, is also linked with higher rates of success in GDM management. Research to date had focused on women's reaction to a diagnosis of GDM, their mood and quality of life following a diagnosis, and their knowledge or opinions on the management of GDM. This qualitative study explored the attitudes of women with GDM toward these lifestyle changes, specifically diet and exercise. Women were also asked to identify advice that would be useful for other women newly diagnosed with GDM.

METHODS

With ethical approval a qualitative study was conducted using semi-structured interviews which were examined using Thematic Analysis. Patients were invited to participate and gave written consent after a discussion with a study researcher. The question plan for semi-structured interviews was designed with the advice of patient advocates. Recurrent themes were developed until the saturation of data.

RESULTS

Thirty-two women took part in the study. Time, convenience, and lack of educational awareness were common barriers to healthy eating and physical activity plans. Enablers for change included meal planning and organization. Women regarded their diets pre-diagnosis as healthy, with small "tweaks" (such as portion control) required to comply with recommendations. Another significant facilitator to change was support from the woman's partner. This also set a benchmark for plans of diet maintenance within the family structure after pregnancy. Unlike dietary changes, a consistent theme was that exercise was considered a "chore" in managing GDM and was unlikely to be continued in the long term. Practical advice offered by participants for other women with GDM included organization, realistic approaches, and lack of self-blame.

CONCLUSION

Women reported that changes in diet would be more achievable in the long term than changes in exercise patterns. Partners and the clinical team were significant sources of support. Women's views are crucial to providing clinicians with a comprehensive and holistic understanding of disease management. Involving women in self-care decisions and empowering women to manage their own health are key contributors to long-term behavior change as well as service provision and policy implementation.

The Impact of a Lifestyle Intervention on Postpartum Weight Retention Among At-Risk Hispanic Women

INTRODUCTION

This study assesses the impact of a culturally modified, motivationally targeted, individually tailored intervention on postpartum weight retention among Hispanic women with abnormal glucose tolerance during pregnancy.

METHODS

Estudio Parto (Project Aiming to Reduce Type twO diabetes) was an RCT conducted in Western Massachusetts (collected 2013‒2017, analyzed 2018-2020). Hispanic women with blood glucose ≥140 mg/dL (7.77 mmol/L) on routine nonfasting oral glucose challenge test were randomized to a Lifestyle Intervention (n=100) focusing on healthy exercise and diet or to a comparison Health and Wellness Intervention (n=104) with no mention of exercise or diet behavior changes. The primary outcome was change in weight, calculated as the difference between prepregnancy weight and 6-week, 6-month, and 12-month postpartum weight. The secondary outcome was achievement of weight reduction to prepregnancy weight if prepregnancy BMI was normal, or a 5% reduction if prepregnancy BMI was overweight/obese.

RESULTS

In intent-to-treat analyses, there were no significant differences in weight change pattern between the intervention arms across all follow-up timepoints (β=0.03, 95% CI= -3.38, 3.45). However, at 12 months postpartum, women in the Lifestyle Intervention arm had a statistically significant 2.5-fold higher odds of meeting the secondary weight reduction outcome (OR=2.52, 95% CI=1.09, 5.82) than women in the Health and Wellness arm. Regardless of intervention arm, women who reported higher levels of postpartum sports/exercise had a greater decrease in weight (β= -2.39, 95% CI= -4.66, -0.13, p=0.04) than women reporting lower levels.

CONCLUSIONS

In this randomized trial among Hispanic women, no significant overall differences in weight change pattern between intervention arms were observed. Higher levels of self-reported physical activity were associated with greater weight loss in both arms.

Motivation and Problem Solving Versus Mobile 360° Videos to Promote Enrollment in the National Diabetes Prevention Program's Lifestyle Change Program Among People With Prediabetes: Protocol for a Randomized Trial

Background

More than 88 million Americans are at risk of developing type 2 diabetes mellitus (T2DM). The National Diabetes Prevention Program’s Lifestyle Change Program (DPP LCP) has been shown to be effective in reducing the risk of progressing from prediabetes to T2DM. However, most individuals who could benefit from the program do not enroll.

Objective

The aim of this trial is to test the real-world efficacy of 3 mobile phone–based approaches to increasing enrollment in the DPP LCP including a best-practice condition and 2 novel approaches.

Methods

We will conduct a 3-armed randomized clinical trial comparing enrollment and 1-month engagement in the DPP LCP among adults with prediabetes from 2 health care settings. Participants in the best-practice condition will receive SMS-based notifications that they have prediabetes and a link to a website that explains prediabetes, T2DM, and the DPP LCP. This will be followed by a single question survey, “Would you like the DPP LCP to call you to enroll?” Participants in the 2 intervention arms will receive the same best-practice intervention plus either 2 mobile 360° videos or up to 5 brief phone calls from a health coach trained in a motivational coaching approach known as Motivation and Problem Solving (MAPS). We will collect measures of diabetes-related knowledge, beliefs in the controllability of risk for T2DM, risk perceptions for T2DM, and self-efficacy for lifestyle change pre-intervention and 4 weeks later. The primary outcomes of the study are enrollment in the DPP LCP and 4-week engagement in the DPP LCP. In addition, data on the person-hours needed to deliver the interventions as well as participant feedback about the interventions and their acceptability will be collected. Our primary hypotheses are that the 2 novel interventions will lead to higher enrollment and engagement in the DPP LCP than the best-practice intervention. Secondary hypotheses concern the mechanisms of action of the 2 intervention arms: (1) whether changes in risk perception are associated with program enrollment among participants in the mobile 360° video group and (2) whether changes in self-efficacy for lifestyle change are associated with program enrollment among participants in the MAPS coaching group. Finally, exploratory analyses will examine the cost effectiveness and acceptability of the interventions.

Results

The project was funded in September 2020; enrollment began in February 2021 and is expected to continue through July 2022.

Conclusions

We are conducting a test of 2 novel, scalable, mobile phone–based interventions to increase enrollment in the DPP LCP. If effective, they have tremendous potential to be scaled up to help prevent T2DM nationwide.

Development and Evaluation of a Prediabetes Decision Aid in Primary Care: Examining Patient-Reported Outcomes by Language Preference and Educational Attainment

PURPOSE

The purpose of this study was to examine the development and preliminary effectiveness of a novel Prediabetes Decision Aid on adoption of intensive lifestyle interventions (ILIs) and metformin. Little research has focused on increasing uptake of these evidence-based treatments, especially among non-English speakers and those with low educational attainment.

METHODS

Investigators developed an English and Spanish decision aid displaying information about type 2 diabetes (T2DM) risk and treatments to prevent T2DM and prompting patients to identify next steps for management. This pilot study was a single-arm, pretest-posttest trial of 40 adult patients with prediabetes, obesity, and ≥1 office visit within the prior 12 months. Participants reviewed this tool briefly with a study team member, and data were collected on 3 coprimary outcomes: knowledge about T2DM risk, decisional conflict, and intention to adopt treatment. Exploratory outcomes included subsequent documentation of prediabetes in chart notes and adoption of ILIs or metformin.

RESULTS

Almost all participants were women, with nearly half expressing Spanish language preference and low educational attainment. A nonsignificant increase in knowledge was observed across all subgroups. Decisional conflict was significantly reduced from pretest to posttest and was similar between subgroups defined by language preference and educational attainment. While intention to adopt ILIs increased across all subgroups, this change was only significant among Spanish speakers and participants with low educational attainment. At 6 months, 17 participants had subsequent provider documentation of prediabetes, and 12 adopted ILIs or metformin.

CONCLUSIONS

The decision aid improved patient-reported outcomes and promoted treatment adoption in a diverse patient sample.

Risk Factors and Wellness Measures Associated with Prediabetes and Newly Diagnosed Type 2 Diabetes Mellitus in Hispanic Adults

Background: To characterize the associations of clinical risk factors, lifestyle factors, and wellness measures with prediabetes and new type 2 diabetes mellitus (T2DM) diagnosis in Hispanic adults and guide primary prevention. Methods: Sangre Por Salud Biobank enrolled 3733 Hispanic adults from Phoenix, AZ, United States, from 2013 to 2018. This analysis included participants with euglycemia, prediabetes, or new T2DM diagnosis (i.e., no prior T2DM diagnosis) at enrollment. Participants completed a baseline questionnaire on cardiometabolic risk factors and wellness measures and provided biometric measurements. The associations of factors and measures with odds (95% confidence interval) of prediabetes and new T2DM diagnosis were analyzed in logistic regression models. Results: Among 3299 participants with euglycemia (n = 1301), prediabetes (n = 1718), and new T2DM diagnosis (n = 280) at enrollment, 72% were women (n = 2376/3299). In adjusted models, most cardiometabolic risk factors were positively associated with prediabetes and new T2DM diagnosis, with stronger associations for new T2DM diagnosis. Obesity (body mass index ≥30 kg/m² vs. lower) was associated with higher odds of new T2DM diagnosis (3.14 [2.30-4.28]; P < 0.01) than prediabetes versus euglycemia (1.96 [1.66-2.32]; P < 0.01) and Interaction (P = 0.01). Similarly, waist circumference, family history of diabetes, and average systolic and diastolic blood pressure were associated with higher odds of new T2DM diagnosis versus euglycemia than prediabetes versus euglycemia. Using stepwise logistic regression modeling, a parsimonious model of age, family history of diabetes, waist circumference, diastolic blood pressure, passive tobacco exposure, and self-rated general health were associated with new T2DM diagnosis versus euglycemia. Conclusions: In Hispanic adults, modifiable cardiometabolic and lifestyle factors were associated with prediabetes and new T2DM diagnosis. Personalized interventions targeting these factors and measures could guide T2DM primary prevention efforts among Hispanic adults.

Mobile Virtual reality vs. Mobile 360 Video to Promote Enrollment in the Diabetes Prevention Program Amongst Hispanic Adults (Preprint)

Background

Hispanic adults are at increased risk of developing type 2 diabetes. The Diabetes Prevention Program (DPP) reduces the risk of developing type 2 diabetes; however, the rate of enrollment is very low.

Objective

The goal of this pilot project was to determine whether presenting brief motivational mobile videos in virtual reality vs 360° video has differential effects on risk perceptions and enrollment in the DPP.

Methods

Adults with prediabetes were recruited at a clinic serving a low-income Hispanic community. After consenting, the participants completed a baseline survey that collected information about demographics and risk perceptions. All participants then viewed 2 videos. Per random assignment, the videos were presented either using the participant’s smartphone alone (360° video) or were viewed with their smartphone in a virtual reality (VR) cardboard headset. Two weeks later, a follow-up survey collected measures of enrollment in the DPP, risk perceptions, health literacy, the importance of contextual factors related to the decision of whether to enroll in the DPP (eg, distance to the class), and qualitative feedback on the interventions. We used logistic regression to determine whether enrollment in the DPP differed by intervention mode, while accounting for health literacy and contextual factors related to the DPP. We used unpaired t tests to examine differences in change in risk perceptions between groups. Paired t tests were used to examine within-subject changes in risk perceptions.

Results

A total of 116 participants provided complete data. Most participants were middle-aged (mean age 44.6 years; SD 11.9) Hispanic (114/116), female (79/116), with low health literacy (mean score 12.3/20; SD 3.4). Enrollment in the DPP was 44/116 (37.9%) overall but did not differ by group (odds ratio for enrolling in VR group 1.78, 95% CI 0.75-4.3; P=.19). Individuals who rated the distance needed to travel to attend the DPP as more important were less likely to enroll in the DPP (odds ratio 0.56, 95% CI 0.33-0.92; P=.03). Risk perceptions did not differ by group (mean change in 360° video group -0.07, mean change in VR group 0.03, t=0.6, P=.54) and did not change within subjects (mean 0.02, t=0.21, P=.83). Participant feedback suggested that the videos are emotionally engaging and educational.

Conclusions

The videos presented in 360° video and mobile VR had equal efficacy in promoting enrollment in the DPP. Future work to rigorously evaluate this intervention, its mechanism of action, and potential moderators of the efficacy are discussed.

Risk perception of developing diabetes: A concept analysis

BACKGROUND

Cognitive risk perception has been linked to health behavior needed to reduce the risk of developing type 2 diabetes. The concept of risk perception of developing diabetes needed review due to: (a) frequent lack of congruency between perceived and actual risk of developing diabetes, and (b) inconsistent measures for calculating perceived diabetes risk.

DESIGN

The concept analysis was conducted using the Walker and Avant approach.

DATA SOURCES

Dictionary definitions, thesaurus synonyms and antonyms, theoretical sources, and seminal works related generally to risk perception were reviewed. Database searches for studies conducted in the United States measuring perceived risk of developing diabetes, were conducted in PubMed, Embase, and CINAHL; resulting in the selection and review of 23 research articles.

RESULTS

The identified dimensions of perceived diabetes risk were: perceived likelihood, personal risk, general risk, cognitive, emotional, comparative risk, and unrealistic optimism. Some antecedents of perceived diabetes risk were motivational factor, individual difference, contextual factor, cognitive factor, and affective factor. A consequence of perceived diabetes risk was health-promoting behaviors.

CONCLUSIONS

This concept analysis increases clarity of a multidimensional concept, providing a basis for validity for measurements. Consideration of antecedents for perceived diabetes risk will be important as related to diabetes prevention efforts.

Study protocol: Using peer support to aid in prevention and treatment in prediabetes (UPSTART)

BACKGROUND

There is an urgent need to develop and evaluate effective and scalable interventions to prevent or delay the onset of type 2 diabetes mellitus (T2DM).

METHODS

In this randomized controlled pragmatic trial, 296 adults with prediabetes will be randomized to either a peer support arm or enhanced usual care. Participants in the peer support arm meet face-to-face initially with a trained peer coach who also is a patient at the same health center to receive information on locally available wellness and diabetes prevention programs, discuss behavioral goals related to diabetes prevention, and develop an action plan for the next week to meet their goals. Over six months, peer coaches call their assigned participants weekly to provide support for weekly action steps. In the final 6 months, coaches call participants at least once monthly. Participants in the enhanced usual care arm receive information on local resources and periodic updates on available diabetes prevention programs and resources. Changes in A1c, weight, waist circumference and other patient-centered outcomes and mediators and moderators of intervention effects will be assessed.

RESULTS

At least 296 participants and approximately 75 peer supporters will be enrolled.

DISCUSSION

Despite evidence that healthy lifestyle interventions can improve health behaviors and reduce risk for T2DM, engagement in recommended behavior change is low. This is especially true among racial and ethnic minority and low-income adults. Regular outreach and ongoing support from a peer coach may help participants to initiate and sustain healthy behavior changes to reduce their risk of diabetes.

The impact of a randomized controlled trial of a lifestyle intervention on postpartum physical activity among at-risk hispanic women: Estudio PARTO

AIMS

To assess the impact of a culturally modified, motivationally targeted, individually-tailored intervention on postpartum physical activity (PA) and PA self-efficacy among Hispanic women.

METHODS

Estudio PARTO was a randomized controlled trial conducted in Western Massachusetts from 2013-17. Hispanic women who screened positive for gestational diabetes mellitus were randomized to a Lifestyle Intervention (LI, n = 100) or to a comparison Health and Wellness (HW, n = 104) group during late pregnancy. Exercise goals in LI were to meet American College of Obstetrician & Gynecologists guidelines for postpartum PA. The Pregnancy Physical Activity Questionnaire (PPAQ) and the Self-Efficacy for Physical Activity Questionnaire were administered at 6 weeks, 6 months, and 1 year postpartum.

RESULTS

Compared to baseline levels, both groups had significant increases in moderate-to-vigorous PA at 6 months and one year postpartum (i.e., LI: mean change = 30.9 MET-hrs/wk, p = 0.05; HW: 27.6 MET-hrs/wk, p = 0.01), with only LI group experiencing significant increases in vigorous PA (mean change = 1.3 MET-hrs/wk, p = 0.03). Based on an intent-to-treat analysis using mixed effects models, we observed no differences in pattern of change in PA intensity and type over time between intervention groups (all p > 0.10). However, there was the suggestion of a greater decrease in sedentary activity in the LI group compared to the HW group (β = -3.56, p = 0.09).

CONCLUSIONS

In this randomized trial among high-risk Hispanic women, both groups benefitted from participation in a postpartum intervention.

The effects of Anethum graveolens (dill) powder supplementation on clinical and metabolic status in patients with type 2 diabetes

Background

The objective of this study was to investigate the effects of Anethum graveolens (dill) powder supplementation on glycemic control, lipid profile, some antioxidants and inflammatory markers, and gastrointestinal symptoms in patients with type 2 diabetes.

Materials and methods

In this study, 42 patients with type 2 diabetes were randomly allocated to intervention and control groups and received either 3 g/day dill powder or placebo (3 capsules/day, 1 g each). Fasting blood sugar, insulin, homeostatic model assessment of insulin resistance, lipid profile, high-sensitivity C-reactive protein, total antioxidant capacity, malondialdehyde and gastrointestinal symptoms were measured in all of the subjects at baseline and postintervention.

Results

The dill powder supplementation significantly decreased the mean serum levels of insulin, homeostatic model assessment of insulin resistance, low-density lipoprotein cholesterol, total cholesterol and malondialdehyde in the intervention group in comparison with the baseline measurements (P < 0.05). Furthermore, the mean serum levels of high-density lipoprotein and total antioxidant capacity were significantly increased in the intervention group in comparison with the baseline measurement (P < 0.05). Colonic motility disorder was the only gastrointestinal symptom whose frequency was significantly reduced by supplementation (P = 0.01). The mean changes in insulin, low-density lipoprotein cholesterol, total cholesterol and malondialdehyde were significantly lower in the intervention group than in the control group (P < 0.05). In addition, the mean changes in high-density lipoprotein were significantly higher in the intervention group than in the control group (P < 0.05).

Conclusion

Dill powder supplementation can be effective in controlling the glycemic, lipid, stress oxidative and gastrointestinal symptoms in patients with type 2 diabetes.

Barriers and facilitating factors in the prevention of diabetes type 2 and gestational diabetes in vulnerable groups: A scoping review

Aims

Type 2 diabetes mellitus (T2DM) and gestational diabetes (GDM) are globally on the rise, accompanied by comorbidities and associated health costs. Increased physical activity, healthy nutrition, and weight loss have shown the potential to prevent T2DM/GDM. Despite this, reaching vulnerable groups remains a key challenge. The aim of this scoping review was to identify barriers and facilitating factors in the prevention of T2DM/GDM in vulnerable groups.

Methods

We conducted a systematic literature search in May 2018, updated in September 2019, in several databases (e.g. PubMed, Embase) to identify barriers and facilitating factors in the prevention of T2DM/GDM in vulnerable groups. Two reviewers independently screened the results. Extracted data was charted, categorized, and summarized.

Results

We included 125 articles. Ninety-eight studies were extracted, and eight categories of barriers and facilitating factors were formed. The most common categories of barriers were limited knowledge, family/friends, and economic factors, and the most common categories of facilitating factors were family/friends, social support, and knowledge.

Conclusion

This scoping review identified various barriers and facilitating factors in vulnerable groups. Preventive interventions should consider these barriers and facilitating factors in developing preventive interventions or in adapting existing ones.

Perspectives of health educators and interviewers in a randomized controlled trial of a postpartum diabetes prevention program for Latinas: a qualitative assessment

Background

Lifestyle interventions regularly rely on study staff to implement the intervention and collect outcomes data directly from study participants. This study describes the experiences of project staff in two randomized controlled trials of a postpartum lifestyle intervention to reduce risk factors for type 2 diabetes in Latinas. Latinas are the fastest growing minority group in the U.S. and have the highest rates of type 2 diabetes after a diagnosis of gestational diabetes mellitus. The challenges of implementing lifestyle interventions for postpartum women have been poorly documented.

Methods

A qualitative focus group was conducted with eight staff members (five health educators and three health interviewers) involved in Proyecto Mamá and Estudio Parto. The discussion was audio recorded, transcribed, and coded in NVivo. Focus group topics included: 1) participant recruitment, 2) participant retention, 3) implementation of the lifestyle intervention, 4) assessment of behavior change, 5) overall challenges and rewarding aspects of the trial, and 6) recommended changes for future trials.

Results

Key themes emerged regarding enabling factors and barriers to implementing a lifestyle intervention in postpartum Latinas. Enabling factors included: a) the staff’s belief in the importance of the intervention, b) opportunities associated with the longitudinal nature of the trial, c) belief that the staff could empower participants to make behavior change, d) benefits of flexible intervention sessions, and e) connection with participants due to shared cultural backgrounds. Barriers included: a) participant stressors: home, food, and financial insecurity, b) low health literacy, c) issues related to recent immigration to the continental U.S., d) handling participant resistance to behavior change, e) involvement of family members in assessment visits, f) limitations of the assessment tools, and g) time limitations.

Conclusions

Findings highlight the challenging contexts that many study participants face, and shed light on the potentially influential role of health educators and interviewers in intervention implementation and data collection. Specific recommendations are made for strategies to improve adherence to diabetes prevention programs in postpartum underserved and minority populations in this challenging, transitional period of life.

Diabetes Risk Factor Knowledge Varies Among Multiracial College Students

All racial/ethnic groups are at higher risk for type 2 diabetes compared to whites, but it is unknown if young adults recognize their risk. Risk knowledge and individual risk perception were examined in 1579 multiracial urban college students. Students have little knowledge of diabetes risk factors; identifying less than three of ten. Considerable variation exists in the understanding of risk; only .02 % of Asian, 14.0 % of Hispanic and 22.8 % of black students recognized that their race increased risk. Among those with ≥3 risk factors (n = 541) only 39 % perceived their risk. These under-estimators had lower knowledge scores (p = .03) than those who acknowledged their risk; indicating that the cause of under-estimating risk may be, at least, in part due to a lack of information. There is a pressing need to heighten understanding of type 2 diabetes risk among young adults to decrease the future burden of this disease.

A systematic review of interventions for Hispanic women with or at risk of Gestational diabetes mellitus (GDM)

BACKGROUND AND OBJECTIVE

Gestational Diabetes Mellitus (GDM) is a serious health concern for pregnant women, with Hispanic women at particular risk for developing the condition. The aim of this review was to critically examine GDM intervention programs for Hispanic women, in the United States of America (US).

METHODS

English and Spanish electronic databases were searched for relevant studies published between 1995 and 2015. Eligible study designs included randomized controlled trial, pre/post-test and quasi experimental methods.

RESULTS

Findings indicated that there was a dearth of literature reporting on GDM interventions for Hispanic women and just seven papers met inclusion criteria. These seven studies were included in the review and they reported on interventions for: (1) pregnant women at high risk of developing GDM; (2) pregnant women with GDM. Results suggest that a combination of intensive counselling over a prolonged period of time, together with a low calorie, possibly low glycemic index diet, produces best results.

CONCLUSION

The review found that intensive nutritional counselling approaches which promote low calorie/low GI diets appear to be most effective in BGL management in this population. Interventions that are delivered in Spanish and culturally tailored may be more acceptable to participants. More research is needed to develop suitable interventions to improve GDM management among Hispanic women.

Patient Perceptions About Prediabetes and Preferences for Diabetes Prevention

PURPOSE

The purpose of this study was to explore how adults with prediabetes perceive their risk of developing diabetes and examine their preferences for evidence-based treatment options to prevent diabetes.

METHODS

A qualitative study was conducted in 2 large Midwest primary care practices, involving in-depth semistructured interviews with 35 adult patients with prediabetes.

RESULTS

This ethnically diverse (77% nonwhite) sample of middle-aged primary care patients exhibited multiple diabetes risk factors. Knowledge gaps about prediabetes and its medical management were pervasive. Most patients overestimated the risk of developing diabetes and were not familiar with evidence-based treatment options for prediabetes. They suggested that receiving brief, yet specific information about these topics during the study interview motivated them to act. The majority of participants considered both intensive lifestyle intervention and metformin acceptable treatment options. Many preferred initial treatment with intensive lifestyle intervention but would take metformin if their efforts at lifestyle change failed and their primary care physician recommended it. Some participants expressed wanting to combine both treatments.

CONCLUSIONS

This qualitative study highlights potential opportunities to promote patient-centered dialogue about prediabetes in primary care settings. Providing patients specific information about the risk of developing diabetes and evidence-based treatment options to prevent or delay its onset may encourage action. Physicians' prediabetes counseling efforts should be informed by the finding that most patients consider both intensive lifestyle intervention and metformin acceptable treatment options.

Proyecto Mamá: a lifestyle intervention in overweight and obese Hispanic women: a randomised controlled trial--study protocol

BACKGROUND

The proportion of women entering pregnancy overweight or obese has been rising and, in turn, is associated with adverse maternal and fetal outcomes. Gestational weight gain (GWG) exceeding Institute of Medicine (IOM) guidelines further increases health risks and has been independently associated with postpartum weight retention. Hispanic women are disproportionately affected by overweight and obesity, but have had limited access to interventions that promote healthy lifestyles due to cultural, socioeconomic, and language barriers. Therefore, the overall goal of this randomized controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce excess GWG, increase postpartum weight loss, and improve maternal metabolic status among overweight/obese Hispanic women.

METHODS/DESIGN

Overweight/obese Hispanic women are recruited in early pregnancy and randomly assigned to a Lifestyle Intervention (n = 150) or a Comparison Health and Wellness (control) intervention (n = 150). Multimodal contacts (i.e., in-person, telephone counseling, and mailed print-based materials) are used to deliver the intervention from early pregnancy (12 weeks gestation) to 6 months postpartum, with follow-up to 1 year postpartum. Targets of the intervention are to achieve IOM Guidelines for GWG and postpartum weight loss; American Congress of Obstetrician and Gynecologist guidelines for physical activity; and American Diabetes Association guidelines for diet. The intervention draws from Social Cognitive Theory and the Transtheoretical Model and includes strategies to address the specific social, cultural, and economic challenges faced by low-income Hispanic women. Assessments are conducted at baseline (~10 weeks gestation), mid pregnancy (24-28 weeks gestation), late pregnancy (32-34 weeks gestation) and postpartum at 6-weeks, 6-months, and 12-months by bicultural and bilingual personnel blinded to the intervention arm. Efficacy is assessed via GWG, postpartum weight loss, and biomarkers of glycemic control, insulin resistance, and cardiovascular disease risk factors. Changes in physical activity and diet are measured via 7-day accelerometer data and 24-h dietary recalls at each assessment time period.

DISCUSSION

Hispanic women are the fastest growing minority group in the U.S. and are disproportionately affected by overweight and obesity. This randomised trial uses a high-reach, low-cost strategy that can readily be translated into clinical practice in underserved and minority populations.

Public awareness about diabetes: cross sectional study of Lithuania's residents

BACKGROUND

Type 2 diabetes is a growing health problem globally; however, awareness about diabetes remains low.

AIM

To assess the public perception of diabetes--how much does the public know about it? What are the beliefs about this challenging issue?

METHODS

A public opinion survey was performed in April 2012. Interviews with a random sample of 1,002 residents of Lithuania aged 16-74 were conducted in the households of the respondents. This sample took into account age, sex, education, employment, family status, and the size of the residential location. The topics covered by the 15-item questionnaire used for these interviews concerned the perceived severity of different health conditions and the respondents' knowledge of diabetes risk factors and normal glycemic indicators as well as their perceptions related to diabetes and insulin.

RESULTS

More than half (56.3%) of respondents had previously undergone the glycemic control test, 33.8% of study participants were familiar with the normal parameters of glycemia. Diabetes was ranked fourth among 13 health problems (the top three were attributed to malignancies, AIDS and mental illnesses). The highest score of all risk factors for developing diabetes was attributed to obesity; however, obesity was never mentioned in associating with diabetes by participants. The perceptions people had about diabetes revealed marginally medicalized images of this health condition.

CONCLUSIONS

Study findings suggest the potential social stigmatization of diabetes and encourage looking for new ways in approaching the community as well as individual diabetic patients in regard to the issue of diabetes.

Investigating diet and physical activity in Malaysia: education and family history of diabetes relate to lower levels of physical activity

The National Health and Morbidity Survey (NHMS, 2011), estimates that the number of Malaysian adults suffering from type 2 diabetes has increased from 8.3 to 31.2% since 1996. This study is a preliminary investigation of possible factors contributing to this epidemic. Knowledge of diabetes, health locus of control, diet and exercise habits, as well as family history, education level and other demographic factors to better understand the correlates of risky and healthy behaviors. This was done as part of a larger initiative to improve prevention efforts. Questionnaires were completed by 770 individuals from three Malaysian states: Selangor, Penang, and Terengganu. Findings showed that people with better health knowledge and those who have a family history of type 2 diabetes were more likely to have healthy diets. Also, health knowledge related to lower alcohol consumption. Participants with diabetic family members, however, also reported higher levels of stress. Counterintuitively, higher educational levels, higher internal locus of control, better health knowledge, as well as a family history of diabetes all correlated with lower levels of physical activity. Thus, it is suggested that, while increasing health knowledge will be important in addressing the type 2 diabetes epidemic in Malaysia, especially in relation to diet, other cultural factors, specifically norms related to exercise and physical activity, also need to be addressed if the spread of type 2 diabetes is to be addressed over the long term.

Estudio Parto: postpartum diabetes prevention program for hispanic women with abnormal glucose tolerance in pregnancy: a randomised controlled trial - study protocol

Background

Diabetes and obesity have reached epidemic proportions in the U.S. with rates consistently higher among Hispanics as compared to non-Hispanic whites. Among Hispanic women diagnosed with gestational diabetes mellitus (GDM), 50% will go on to develop type 2 diabetes within 5 years of the index pregnancy. Although randomised controlled trials among adults with impaired glucose tolerance have shown that diet and physical activity reduce the risk of type 2 diabetes, such programs have not been tested in high-risk postpartum women. The overall goal of this randomised controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce risk factors for type 2 diabetes and cardiovascular disease among postpartum Hispanic women with a history of abnormal glucose tolerance during pregnancy.

Methods/Design

Hispanic pregnant women who screen positive for GDM will be recruited and randomly assigned to a Lifestyle Intervention (n = 150) or a Health & Wellness (control) Intervention (n = 150). Multimodal contacts (i.e., in-person, telephone, and mailed materials) will be used to deliver the intervention from late pregnancy (29 weeks gestation) to 12 months postpartum. Targets of the intervention are to achieve Institute of Medicine Guidelines for postpartum weight loss; American Congress of Obstetrician and Gynecologist guidelines for physical activity; and American Diabetes Association guidelines for diet. The intervention draws from Social Cognitive Theory and the Transtheoretical Model and addresses the specific cultural and environmental challenges faced by low-income Hispanic women. Assessments will be conducted at enrollment, and at 6-weeks, 6-months, and 12-months postpartum by trained bicultural and bilingual personnel blinded to the intervention arm. Efficacy will be assessed via postpartum weight loss and biomarkers of insulin resistance and cardiovascular risk. Changes in physical activity and diet will be measured via 7-day actigraph data and three unannounced 24-hour dietary recalls at each assessment time period.

Discussion

Hispanic women are the fastest growing minority group in the U.S. and have the highest rates of sedentary behavior and postpartum diabetes after a diagnosis of GDM. This randomised trial uses a high-reach, low-cost strategy that can readily be translated into clinical practice in underserved and minority populations.

The Impact of Hispanic Ethnicity on Knowledge and Behavior Among Patients With Diabetes

PURPOSE

The purpose of the study was to measure the current level of awareness of the American Heart Association's 7 risk/protective factors of cardiovascular health among adults with diabetes of Hispanic and non-Hispanic origin and to identify factors associated with knowledge deficits.

METHODS

A cross-sectional survey measured demographic data, personal behaviors/health factors, cardiovascular disease (CVD) history, and knowledge of 7 components of ideal cardiovascular health (smoking, obesity, exercise, diet, cholesterol, blood pressure, and blood glucose). A subset of 331 Hispanic and white patients with diabetes was surveyed. Knowledge scores were dichotomized between full knowledge (7 components) and less than full knowledge and compared between ethnicities using multiple logistic regression.

RESULTS

Seventy-nine percent of surveys were returned; 50.5% of subjects were Hispanic. Median age was 64.5 years with 60.7% being female. Two-thirds of the sample completed high school and 26% reported comorbid CVD. Recognition of diabetes as a risk factor didn't differ by ethnicity. Thirty-five percent of respondents identified 7 American Heart Association risk factors. Hispanics were less likely to identify 7 components. After adjustment for education and English literacy, the difference disappeared. Better knowledge was positively associated with healthier behaviors for high cholesterol, hypertension, and exercise only among white patients.

CONCLUSIONS

Hispanic patients with diabetes exhibit less knowledge about CVD risk/protective factors due to lower education and English literacy. Educational interventions should be tailored to those with less education/limited English proficiency.

Families United/Familias Unidas

Purpose

The purpose of the Families United/Familias Unidas study was to evaluate the feasibility and efficacy of group office visits on reducing diabetes risk in a multiethnic, primary care population.

Methods

Adults, ages 18 to 70 years, with any diabetes risk factor were recruited to attend 12 group office visits over 6 months. Each participant identified 1 support person, age 14 to 70 years, to accompany them. Data were collected at baseline, postintervention, 6 months, and 12 months. Primary outcome measures were reduction in the total number of predefined, modifiable risk factors (ie, body mass index ≥25 kg/m2; waist circumference ≥88 cm [women], ≥102 cm [men]; blood pressure ≥140/90 mm Hg; hemoglobin A1C ≥5.7%; fasting insulin ≥15 µU/mL; glycemic index ≥52.5% [women], ≥53.4% [men]; and physical activity <150 min/wk).

Results

Thirty-nine participants/supporters completed the intervention (mean age 47.8 ± 12.3 years, 69.2% female, 61.5% white, 35.9% Latino). Risk reduction analysis included only participants/supporters who remained paired at the intervention’s end (n = 36). At baseline, primary participants (n = 18) had an average of 4.8 ± 1.6 (standard error) predefined risk factors; supporters (n = 18), 4.1 ± 1.4. Primary participants’ risk factors decreased approximately 15% immediately after the 6-month intervention (absolute reduction of 1.1 risk factors) and increased to ~20% reduction 1 year postintervention (absolute reduction of 1.4 risk factors). Risk reduction was primarily due to decreases in dietary glycemic index and fasting insulin levels.

Conclusions

Group visits provide an innovative and potentially efficacious model of diabetes prevention in multiethnic patients with heterogeneous risk factors.

Exploring risk, prevention and educational approaches for the non-diabetic offspring of patients with type 2 diabetes--a qualitative study

AIM

To understand the knowledge and perceptions of type 2 diabetes and to explore preferable educational strategies in the non-diabetic offspring of patients with the disease.

BACKGROUND

Type 2 diabetes is an increasingly prevalent disease with significant long-term consequences. Offspring of patients with type 2 diabetes have an increased risk of developing the disease compared with the general population. Previous studies have shown that offspring have a poor perception of their own risk.

DESIGN

A qualitative study was carried out using semi-structured one-to-one interviews. Analysis was completed using a structured framework approach.

METHODS

Research was carried out during January-March 2011 in the north east of UK. Six offspring of patients diagnosed with the disease were interviewed.

RESULTS

Participants balanced positive and negative aspects of their lifestyle behaviours to estimate their own risk. They had adequate knowledge of healthy lifestyle behaviours, but were uncertain about the long-term effects and seriousness of the disease and the role of inheritance. Behavioural changes at an individual level would only be motivated by an event, which would impact on their own health. Participants believed that 'fear'-based strategies to health promotion would be most effective to encourage behaviour change.

CONCLUSION

Knowledge of individual risk and why diabetes was serious was limited and variable. The health behaviours of this at-risk group were complex. Nurses engaged in the care of at-risk individuals must take this complexity into account when developing and implementing multi-faceted strategies to improve awareness.

Families United/Familias Unidas: development and implementation of a family-based group office visit model for the primary prevention of type 2 diabetes

PURPOSE

The purpose of this study is to describe the development and implementation of a new diabetes prevention intervention that combines the benefits of family support with the group office model. Intensive lifestyle modification can effectively delay the onset of type 2 diabetes, yet health providers are challenged in translating these results to their patients. The group outpatient visit model can provide a means to address prevention issues in a financially sustainable manner.

METHODS

Materials from the Diabetes Prevention Program and a previously developed group office visit program were combined to create the Families United/Familias Unidas curriculum. The session content utilized a multiculturally tailored approach designed to help participants decrease portion size, decrease carbohydrate intake, increase physical activity, and increase resiliency. Adults aged 18 to 70 were recruited who had any diabetes risk factors but did not have diabetes. Eligible participants enlisted a support person, aged 14 to 70, to join them in the 6-month group office visit intervention.

RESULTS

Twenty-nine pairs (n = 58) of primary participants plus support persons were recruited. Participants' average age was 45; 74% were female; 56.9% identified themselves as white and 37.9% as Hispanic/Latino. Over one-third had 4 or more diabetes risk factors. Twelve family group office visits were delivered over 6 months. The attendance rate for those who attended at least one session was 72%.

CONCLUSIONS

Group office visits can provide a new sustainable model for diabetes prevention and are a natural fit for primary care physicians in collaboration with other health care professionals, such as dieticians or diabetes educators.

Outcomes of a Latino community-based intervention for the prevention of diabetes: the Lawrence Latino Diabetes Prevention Project

OBJECTIVES

We tested the effectiveness of a community-based, literacy-sensitive, and culturally tailored lifestyle intervention on weight loss and diabetes risk reduction among low-income, Spanish-speaking Latinos at increased diabetes risk.

METHODS

Three hundred twelve participants from Lawrence, Massachusetts, were randomly assigned to lifestyle intervention care (IC) or usual care (UC) between 2004 and 2007. The intervention was implemented by trained Spanish-speaking individuals from the community. Each participant was followed for 1 year.

RESULTS

The participants' mean age was 52 years; 59% had less than a high school education. The 1-year retention rate was 94%. Compared with the UC group, the IC group had a modest but significant weight reduction (-2.5 vs 0.63 lb; P = .04) and a clinically meaningful reduction in hemoglobin A1c (-0.10% vs -0.04%; P = .009). Likewise, insulin resistance improved significantly in the IC compared with the UC group. The IC group also had greater reductions in percentage of calories from total and saturated fat.

CONCLUSIONS

We developed an inexpensive, culturally sensitive diabetes prevention program that resulted in weight loss, improved HbA1c, and improved insulin resistance in a high-risk Latino population.
