Factors affecting the mercury concentration in the hair of young residents of the Vologda region, Russia.

ABSTRACT: The main aim of this study was to assess the level of mercury accumulation in the hair of students studying in the Vologda Region, Russia. Particular attention is devoted to clarifying the relationship between the metal concentration in the hair and the amount of fish in the diet. It was found that the mercury content in the hair of Vologda Region residents aged 17-21 is in the range from less than 0.002 mg/kg to 1.69 mg/kg, the median of the indicator for the entire sample is 0.14 mg/kg. The median value of mercury content in the hair of males (0.12 mg/kg) is lower than in the hair of females (0.16 mg/kg). The lowest metal concentrations were observed in individuals living in the city of Cherepovets and the highest metal concentration among the entire sample and in females in the western areas, and males in the eastern areas of the Vologda Region. The concentration of metal in the hair of the urban population is lower than in subjects living in rural areas. A higher metal content in the hair was recorded in individuals whose diet usually contains fish twice a month.

Project description:BackgroundResidents completing competency-based medical education for postgraduate training face many challenging situations that may compromise their well-being or result in exhaustion or burnout. Factors described in self-determination theory and grit are important for residents' achievement of learning outcomes and well-being. This study explored the relationships among internal motivation, grit, well-being, and related factors among non-Western Asian residents.MethodsWe conducted an explanatory sequential mixed-methods survey-based study to explore correlations among satisfaction with basic psychological needs, grit, and well-being from September to November 2021 among residents at Ramathibodi Hospital, Mahidol University, Thailand. Data were collected with the Basic Psychological Needs Scale, Short Grit Scale, and World Health Organization-Five Well-Being Index. Next, participants with the highest and lowest scores for each scale were purposively invited to participate in semi-structured interviews. Interview data underwent thematic analysis and data collection continued until saturation was reached.ResultsIn total, 245 residents (51% major ward, 65% female) completed the survey. There were strong associations between internal motivation, grit, and well-being (r = 0.46-0.90). Female residents had higher autonomy and relatedness scores than males (p = 0.04 and p = 0.01, respectively), and residents with less family responsibility had higher relatedness scores than other residents (p = 0.01). Residents who got more sleep had higher autonomy, relatedness, and well-being scores than those that slept less (p < 0.05). Residents who exercised > 5 times/week had higher well-being scores than other residents (p < 0.01). Thirty residents completed interviews. The thematic analysis revealed internal motivation, grit, and well-being were promoted by a supportive learning environment, a well-designed curriculum, actions and personalities of faculty members, and good personal factors.ConclusionInternal motivation is significantly correlated with residents' grit, well-being, gender, family burdens, exercise, and sleep hours. Priority should be given to promoting internal motivation, grit, and well-being among residents by enhancing a positive learning environment, creating well-designed curricula, fostering good characteristics and actions among faculty members, and supporting residents' personal lives.
