Gender Differences in Lay Knowledge of Type 2 Diabetes Symptoms Among Community-dwelling Caucasian, Latino, Filipino, and Korean Adults - DiLH Survey

PURPOSE: The purpose of this study was to explore gender differences in lay knowledge of type 2 diabetes symptoms among community-dwelling Caucasian, Latino, Filipino, and Korean Americans. DESIGN AND METHODS: A cross-sectional survey was administered to a convenience sample of 904 adults (172 Caucasians, 248 Latinos, 234 Koreans, and 250 Filipinos) without diabetes at community events, community clinics, churches, and online in the San Francisco Bay Area and San Diego from August to December 2013. Participants were asked to describe in their own words signs and/or symptoms of diabetes. A multiple logistic regression analysis was performed to examine the association of lay symptom knowledge with gender after controlling for potential confounding factors. RESULTS: Overall, the average age of the sample populations was 44 (SD ±16.1) years, 36% were male, and 58% were married. Increased thirst/dry mouth following increased urinary frequency/color/odor and increased fatigue/lethargy/low energy were the most frequently reported signs and symptoms (19.8%, 15.4%, and 13.6%, respectively). After controlling for known confounding factors, women were 1.6 (95% confidence interval, 1.2-2.3, P = .004) times more likely than men to report at least 1 diabetes symptom. However, this gender difference in knowledge of diabetes signs and symptoms did not significantly differ across Caucasians, Latinos, Filipinos, and Korean Americans (P = .87). CONCLUSION: The findings underscore the importance of improving public knowledge and awareness of signs and symptoms of diabetes, particularly in men

Thirst in Critically Ill Patients: From Physiology to Sensation

Critically ill patients often report distressful episodes of severe thirst, but the complex biochemical, neurohormonal mechanisms that regulate this primal sensation still elude clinicians. The most potent stimuli for thirst are subtle increases in plasma osmolality. These minute changes in osmolality stimulate central osmoreceptors to release vasopressin (also known as antidiuretic hormone). Vasopressin in turn acts on the kidneys to promote the reabsorption of water to correct the increased osmolality. If this compensatory mechanism fails to decrease osmolality, then thirst is triggered to motivate drinking. In contrast, thirst induced by marked volume loss, or hypovolemic thirst, is subject to the tight osmoregulation of the renin-angiotensin aldosterone system and accompanying adrenergic agonists. Understanding the essential role that thirst plays in salt and water regulation can provide clinicians with a better appreciation for the complex physiology that underlies this intense sensation

Factors Associated with Underestimation of Weight Status among Caucasian, Latino, Filipino, and Korean Americans--DiLH Survey.

ObjectiveTo describe weight misperception and to examine the influence of sociodemographic factors on underestimation of weight status in Caucasian, Latino, Filipino, and Korean Americans.DesignData from 886 non-pregnant adults who participated in a cross-sectional survey administered in English, Spanish, and Korean were analyzed. The actual weight status derived from the participants' body mass index (BMI) categories and their perceived weight status were compared. A multiple logistic regression model was used to explore if underestimation of weight status was associated with ethnicity, sex, and education level.ResultsCaucasians, Latinos, Filipinos, and Koreans represented 19.4%, 26.8%, 27.4%, and 26.4%, respectively, of the total sample of 886. Overall, two in three participants correctly perceived their weight status, but 42% of Latinos underestimated their weight status and 22% of Koreans overestimated their weight status. Latino ethnicity, male, and low education (high school) were related to greater underestimation of weight status (P < .05). In contrast, Korean ethnicity was related to less underestimation of weight status (P < .05).ConclusionsMisperception of weight status should be counted in any efforts to develop a weight management intervention for Latino and Korean Americans

Development of a Mobile Phone-Based Weight Loss Lifestyle Intervention for Filipino Americans with Type 2 Diabetes: Protocol and Early Results From the PilAm Go4Health Randomized Controlled Trial.

BackgroundFilipino Americans are the second largest Asian subgroup in the United States, and were found to have the highest prevalence of obesity and type 2 diabetes (T2D) compared to all Asian subgroups and non-Hispanic whites. In addition to genetic factors, risk factors for Filipinos that contribute to this health disparity include high sedentary rates and high fat diets. However, Filipinos are seriously underrepresented in preventive health research. Research is needed to identify effective interventions to reduce Filipino diabetes risks, subsequent comorbidities, and premature death.ObjectiveThe overall goal of this project is to assess the feasibility and potential efficacy of the Filipino Americans Go4Health Weight Loss Program (PilAm Go4Health). This program is a culturally adapted weight loss lifestyle intervention, using digital technology for Filipinos with T2D, to reduce their risk for metabolic syndrome.MethodsThis study was a 3-month mobile phone-based pilot randomized controlled trial (RCT) weight loss intervention with a wait list active control, followed by a 3-month maintenance phase design for 45 overweight Filipinos with T2D. Participants were randomized to an intervention group (n=22) or active control group (n=23), and analyses of the results are underway. The primary outcome will be percent weight change of the participants, and secondary outcomes will include changes in waist circumference, fasting plasma glucose, glycated hemoglobin A1c, physical activity, fat intake, and sugar-sweetened beverage intake. Data analyses will include descriptive statistics to describe sample characteristics and a feasibility assessment based on recruitment, adherence, and retention. Chi-square, Fisher's exact tests, t-tests, and nonparametric rank tests will be used to assess characteristics of randomized groups. Primary analyses will use analysis of covariance and linear mixed models to compare primary and secondary outcomes at 3 months, compared by arm and controlled for baseline levels.ResultsRecruitment was completed in January, 2016, and participant follow-up continued through June, 2016. At baseline, mean age was 57 years, 100% (45/45) of participants self-identified as Filipinos, and the cohort was comprised of 17 males and 28 females. Overall, participants were obese with a baseline mean body mass index of 30.2 kg/m2 (standard deviation 4.9). The majority of participants were immigrants (84%, 38/45), with 47% (21/45) living in the United States for more than 10 years. One third of all participants (33%, 15/45) had previously used a pedometer.ConclusionsThis study will provide preliminary evidence to determine if the PilAm Go4Health weight loss lifestyle intervention is feasible, and if the program demonstrates potential efficacy to reduce risks for metabolic syndrome in Filipinos with T2D. Positive results will lend support for a larger RCT to evaluate the effectiveness of the PilAm Go4Health intervention for Filipinos.ClinicaltrialClinicalTrials.gov: NCT02290184; https://clinicaltrials.gov/ct2/show/NCT02290184 (Archived at http://www.webcitation.org/6k1kUqKSP)
