OBJECTIVETo evaluate the effect of a culturally sensitive diabetes self-management education program that uses a low-cost, peer-educator format (Project Dulce) on glucose control and metabolic parameters in low-income Mexican Americans with type 2 diabetes.RESEARCH DESIGN AND METHODSA total of 207 Mexican-American patients recruited from federally funded community health centers in San Diego County with HbA1c >8% were randomly assigned to the Project Dulce peer intervention or continuation of standard diabetes care. The primary outcome of interest was HbA1c.RESULTSThe majority of subjects were born in Mexico, were female, were middle-aged, had less than an eighth-grade education, and had high baseline HbA1c levels. Significant time-by-group interaction effects for HbA1c (P = 0.02) and diastolic blood pressure (P = 0.04) indicated that the Project Dulce group exhibited greater improvement (i.e., decreases) across time. Within-group analyses showed that the intervention group exhibited significant improvements from baseline to month 4 in absolute levels of HbA1c (−1.7%, P = 0.001) and HDL cholesterol (+1.4 mg/dL, P = 0.01) and from baseline to month 10 in absolute levels of HbA1c (−1.5%, P = 0.01), total cholesterol (−7.2 mg/dL, P = 0.04), HDL cholesterol (+1.6 mg/dL, P = 0.01), and LDL cholesterol (−8.1 mg/dL, P = 0.02). No significant changes were noted in the control group.CONCLUSIONSThis randomized trial, using the Project Dulce model of culturally sensitive, peer-led education, demonstrates improvement in glucose and metabolic control and suggests that this low-cost approach to self-management education for high-risk diabetic populations is effective.
Background This study examined whether thirdhand smoke (THS) persists in smokers’ homes after they move out and nonsmokers move in, and whether new nonsmoking residents are exposed to THS in these homes. Methods Homes of 100 smokers and 50 nonsmokers were visited before the residents moved out. Dust, surfaces, and air and participants’ fingers were measured for nicotine and children’s urine samples were analyzed for cotinine. The new residents who moved into these homes were recruited if they were nonsmokers. Dust, surfaces, and air, and new residents’ fingers were examined for nicotine in 25 former smoker and 16 former nonsmoker homes. A urine sample was collected from the youngest resident. Results Smoker homes’ dust, surface, and air nicotine decreased after the change of occupancy (p<.001); yet dust and surfaces showed higher contamination levels in former smoker homes than former nonsmoker homes (p<.05). Nonsmoking participants’ finger nicotine was higher in former smoker homes compared to former nonsmoker homes (p<.05). Finger nicotine levels among nonsmokers living in former smoker homes were significantly correlated with dust and surface nicotine and urine cotinine. Conclusions These findings indicate that THS accumulates in smokers’ homes and persists when smokers move out even after homes remain vacant for two months and are cleaned and prepared for new residents. When nonsmokers move into homes formerly occupied by smokers, they encounter indoor environments with THS polluted surfaces and dust. Results suggest that nonsmokers living in former smoker homes are exposed to THS in dust and on surfaces.
OBJECTIVEType 2 diabetes is growing in epidemic proportions and disproportionately affects lower-income, diverse communities. Text messaging may provide one of the most rapid methods to overcome the “digital divide” to improve care.RESEARCH DESIGN AND METHODSA randomized, nonblinded, parallel-groups clinical trial design allocated N = 126 low-income, Hispanic participants with poorly controlled type 2 diabetes to receive the Dulce Digital intervention or usual care (UC). Dulce Digital participants received up to three motivational, educational, and/or call-to-action text messages per day over 6 months. The primary outcome was HbA1c; lipids, blood pressure, and BMI were secondary outcomes. Satisfaction and acceptability were evaluated via focus groups and self-report survey items.RESULTSThe majority of patients were middle-aged (mean age 48.43 years, SD 9.80), female (75%), born in Mexico (91%), and uninsured (75%) and reported less than a ninth-grade education level (73%) and mean baseline HbA1c 9.5% (80 mmol/mol), SD 1.3, and fasting plasma glucose 187.17 mg/dL, SD 64.75. A statistically significant time-by-group interaction effect indicated that the Dulce Digital group achieved a significantly greater reduction in HbA1c over time compared with UC (P = 0.03). No statistically significant effects were observed for secondary clinical indicators. The number of blood glucose values texted in by participants was a statistically significant predictor of month 6 HbA1c (P < 0.05). Satisfaction and acceptability ratings for the Dulce Digital intervention were high.CONCLUSIONSUse of a simple, low-cost text messaging program was found to be highly acceptable in this sample of high-risk, Hispanic individuals with type 2 diabetes and resulted in greater improvement in glycemic control compared with UC.
Latina women with prior gestational diabetes mellitus (GDM) are at elevated risk for type 2 diabetes mellitus and cardiovascular disease. Few primary prevention programs are designed for low socioeconomic status, Spanish-speaking populations. We examined the effectiveness of a Diabetes Prevention Program (DPP) translation in low-income Latinas with a history of GDM. Eighty-four Latinas, 18-45 years old with GDM in the past 3 years, underwent an 8-week peer-educator-led group intervention, with tailoring for Latino culture and recent motherhood. Lifestyle changes and diabetes and cardiovascular risk factors were assessed at study baseline, month 3 and month 6. Participants showed significant improvements in lipids, blood pressure, physical activity, dietary fat intake, and fatalistic and cultural diabetes beliefs (p<0.05). [7,8] and can modify CVD risk factors [9,10] in highrisk individuals. In the DPP, lifestyle intervention was effective in reducing diabetes risk by 50 % over 3 years [7]. A handful of community-based DPP translations have shown promising results over relatively short time frames [11,12]. However, limited efforts have been made to translate the DPP for women with a history of GDM [13,14], especially those with low socioeconomic status (SES). This represents a critically missed opportunity [15] given that a GDM diagnosis identifies individuals at a very high risk for future T2DM [1,16] and that lifestyle intervention is an effective diabetes prevention strategy for women with history of GDM [16]. Further, few community-based adaptations of the DPP have been tested in Latinos [17] who, on the whole, experience unique socioeconomic and cultural circumstances that may affect response to traditional intervention programs [18,19].The current single-group pilot study evaluated the feasibility, acceptability, and effectiveness of a group format, peer-educator-administered DPP-adapted lifestyle intervention to reduce T2DM and CVD risk among low SES Latinas with a history of GDM. Peer education models have been shown to be a cost and clinically effective approach to health
Objective The current study examined multiple stress indicators (chronic, perceived, traumatic) in relation to prevalent coronary heart disease (CHD), stroke, and major cardiovascular disease (CVD) risk factors (i.e., diabetes, dyslipidemia, hypertension, current smoking) in the multi-site Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (2010–2011). Methods Participants were 5313 men and women, 18–74 years old, representing diverse Hispanic/Latino ethnic backgrounds, who underwent a comprehensive baseline clinical exam and sociocultural exam with measures of stress. Results Chronic stress burden was related to a higher prevalence of CHD after adjusting for sociodemographic, behavioral and biological risk factors [OR (95% CI) = 1.22, (1.10–1.36)] and related to stroke prevalence in the model adjusted for demographic and behavioral factors [OR (95% CI) = 1.26, (1.03–1.55∂)]. Chronic stress was also related to a higher prevalence of diabetes [OR=1.20, (1.11–1.31)] and hypertension [OR=1.10 (1.02–1.19)] in individuals free from CVD (N=4926). Perceived stress [OR=1.03 (1.01–1.05)] and traumatic stress [OR=1.15 (1.05–1.26)] were associated with a higher prevalence of smoking. Participants who reported a greater number of lifetime traumatic events also unexpectedly showed a lower prevalence of diabetes [OR=.89 (.83–.97)] and hypertension [OR=.88 (.82–.93)]. Effects were largely consistent across age and sex groups. Conclusions The study underscores the utility of examining multiple indicators of stress in relation to health, since the direction and consistency of associations may vary across distinct stress conceptualizations. In addition, the study suggests that chronic stress is related to higher CVD risk and prevalence in Hispanics/Latinos, the largest U.S. ethnic minority group.
Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens. Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective.
Background: The global epidemic of diabetes calls for innovative interventions. This study evaluated the effectiveness of the Project Dulce model, with and without wireless technology, on glycemic control and other clinical and self-reported outcomes in patients with poorly controlled type 2 diabetes in Mexico.Subjects and Methods: Adults with type 2 diabetes and a glycated hemoglobin A1c (HbA1c) level of ≥8% were recruited from Family Medical Unit #27 of the Instituto Mexicano del Seguro Social (IMSS) in Tijuana, México, and randomly assigned to one of three groups: Project Dulce–only (PD); Project Dulce technology-enhanced with mobile tools (PD-TE); or IMSS standard of care/control group (CG). Clinical and self-reported outcomes were assessed at baseline, Month 4, and Month 10. Time-by-group interactions and within-group changes were analyzed.Results: HbA1c reductions from baseline to Month 10 were significantly greater in PD-TE (−3.0% [−33 mmol/mol]) and PD (−2.6% [−28.7 mmol/mol]) compared with CG (−1.3% [−14.2 mmol/mol]) (P = 0.009 and 0.001, respectively). PD-TE and PD also exhibited significant improvement in diabetes knowledge when compared with CG (P < 0.05 for both). No statistically significant differences were detected between PD and PD-TE on these indicators (P = 0.54 and 0.86, respectively). Several within-group improvements were observed on other clinical and self-report indicators but did not vary significantly across groups.Conclusions: Project Dulce with and without wireless technology substantially improved glycemic control and diabetes knowledge in high-risk patients with type 2 diabetes in a Mexican family medical unit, suggesting that integrating peer-led education, nurse coordination, and 3G wireless technology is an effective approach for improving diabetes outcomes in high-risk populations.
Allostatic load provides a useful framework for conceptualizing the multi-system physiological impact of sustained stress and its effects on health and well-being. Research across two decades shows that allostatic load indices predict health outcomes including all cause mortality, and vary with stress and related psychosocial constructs. The study by Slopen and colleagues in this issue provides an example both of the utility of the allostatic load framework, and of limitations in related literature, such as inconsistencies in conceptualization and measurement across studies, and the frequent application of cross-sectional designs. The current article describes these limitations and provides suggestions for further research to enhance the value and utility of the allostatic load framework in biobehavioral medicine research.
