Folate, vitamin B6, and vitamin B12 intake can be important regulators for obesity development. Thus, we investigated the possible association between the intake of these vitamins and the excess body weight or obesity prevalence in the participants of the Cohort of Universities in Minas Gerais (CUME project). This study analyzed cross-sectional data of 2695 graduates and postgraduates from universities in the state of Minas Gerais (801 men, 1894 women, ages 36.2 ± 9.4). The first step consisted of collecting data online, and the second step consisted of blood collecting in the subsample living in the city of Viçosa and its region (Minas Gerais). Excess body weight and obesity prevalence were 38.1% and 10.1%, respectively. Inadequate intake of folate, B6, and B12 were 12, 6.3, and 11.1%, respectively. Beans/lentils and French bread presented the highest contribution to folate intake (23.45% and 10.01%, respectively). Those individuals in the third tertile for folate intake (≥511.12 μg/d) had a lower excess body weight [prevalence ratio (PR): 0.79, confidence interval (CI): 0.71–0.8] and obesity prevalence (PR: 0.60, CI: 0.45–0.78). These associations were maintained when the sample was categorized by sex. In addition, serum folate was positively associated with dietary folate (p for trend = 0.032) and negatively associated with serum homocysteine (p for trend = 0.003) in the subsample. Dietary folate intake was negatively associated with excess body weight and obesity in CUME participants, indicating the relevance of this vitamin dietary assessment.

Background: Chronic pain is a complex phenomenon that brings physical and emotional impairments negatively impacting people's quality of life. The adoption of interventions such as ear acupuncture and dry cupping can represent a treatment option for people with chronic back pain. Objectives: To investigate the effects of ear acupuncture combined with dry cupping therapy on the interference of pain with the daily activities and quality of life of adults with chronic back pain.Methods: An open-label, randomized, parallel-group controlled clinical trial. One hundred and ninety-eight adults were randomized into control (CG -ear acupuncture) or experimental (EG -ear acupuncture combined with dry cupping) groups. Interventions were performed in five sessions, once a week, lasting five weeks. Evaluations were performed before the first session, after the last session, and seven days after the second evaluation, using the Brief Pain Inventory to assess the impact of pain on daily activities and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) to assess the quality of life. Results: Between the initial and final sessions, there were significant changes in daily activities , activity, work, mood, relationships, sleep, and in the physical, psychological and social relationships domains for both the control and experimental groups. Improved perception of quality of life and satisfaction with health were observed for the participants in the experimental group. Conclusion: Ear acupuncture combined with dry cupping showed better results in terms of perception of quality of life and satisfaction with health when compared to ear acupuncture by itself.
