A retrospective study on cholera understanding and WASH (water, sanitation, and hygiene) behavior among adolescents in three regions of La Gonâve, Haiti.

BACKGROUNDS: This study assesses the impact of Water, Sanitation, and Hygiene (WASH) interventions on cholera understanding and hygiene practices in La Gonâve Island, Haiti. It examines the changes after implementing interventions in seven villages across the Downtown, Mountain, and Seaside regions. METHODS: A retrospective investigation surveyed 210 school students from each region using a validated questionnaire. It assessed knowledge, attitudes, practices (KAP), and environmental aspects related to cholera and hygiene. Data analysis involved descriptive statistics and chi-square tests. RESULTS: The study highlights significant disparities in education levels, toilet ownership, and healthcare access. Challenges in finding public toilets (86.67%) and accessing water sources (67.78%) are consistent across regions, with Seaside facing financial constraints (85.00%) and water cost concerns (91.67%). Attitudes toward hygiene vary, with the Mountain region having the highest 'Never' responses for handwashing (38.89%), and Downtown leading in water treatment practices (11.67%). There is a strong willingness to share health knowledge, particularly in Downtown (100.00%). Seaside (83.33%) and Downtown (73.33%) revealed a higher cholera awareness, while nearly half of Mountain students lacked knowledge (54.44%). CONCLUSIONS: This study highlights significant disparities in WASH practices among La Gonâve's adolescents in Downtown, Mountain, and Seaside regions. Urgent interventions are crucial for improving sanitation, ensuring clean water access, and implementing targeted hygiene education, especially in the resource-constrained Mountain and Seaside areas. The findings underscore the vital roles of adolescents and schools in disseminating knowledge, with further research needed to explore intervention differences.

Trends, Social Context, and Transplant Implications of Obesity Among Incident Dialysis Patients in the United States.

BACKGROUND: Kidney transplant programs have variable thresholds to accept obese candidates. This study aimed to examine trends and the social context of obesity among United States dialysis patients and implications for kidney transplant access. METHODS: We performed a retrospective cohort study of 1 084 816 adults who initiated dialysis between January 2007 and December 2016 using the United States Renal Data System data. We estimated national body mass index (BMI) trends and 1-y cumulative incidence of waitlisting and death without waitlisting by BMI category (<18.5 kg/m 2 , ≥18.5 and <25 kg/m 2 [normal weight], ≥25 and <30 kg/m 2 [overweight], ≥30 and <35 kg/m 2 [class 1 obesity], ≥35 and <40 kg/m 2 [class 2 obesity], and ≥40 kg/m 2 [class 3 obesity]). We then used Fine-Gray subdistribution hazard regression models to examine associations between BMI category and 1-y waitlisting with death as a competing risk and tested for effect modification by End Stage Renal Disease (ESRD) network, patient characteristics, and neighborhood social deprivation index. RESULTS: The median age was 65 (interquartile range 54-75) y, 43% were female, and 27% were non-Hispanic Black. From 2007 to 2016, the adjusted prevalence of class 1 obesity or higher increased from 31.9% to 38.2%. Class 2 and 3 obesity but not class 1 obesity were associated with lower waitlisting rates relative to normal BMI, especially for younger individuals, women, those of Asian race, or those living in less disadvantaged neighborhoods ( pinteraction < 0.001 for all). CONCLUSIONS: Obesity prevalence is rising among US incident dialysis patients. Relative to normal BMI, waitlisting rates with class 2 and 3 obesity were lower and varied substantially by region, patient characteristics, and socioeconomic context.
