Article Abstract
Objectives: To investigate the association of dietary patterns (DP) with prediabetes and type 2 diabetes (T2D) among Tibetan adults, first to identify DP associated with abdominal obesity and examine their relationships with prediabetes and T2D. Additionally, the study aims to investigate the mediating effects of body fat distribution and altitude on the associations between these DP and the prevalence of prediabetes and T2D.
Design: An open cohort among Tibetans.
Setting: Community-based.
Participants: The survey recruited 1003 participants registered for health check-ups from November to December 2018 and 1611 participants from December 2021 to May 2022. During the baseline and follow-up data collection, 1818 individuals participated in at least one of the two surveys, with 515 of them participating in both.
Results: Two DP were identified by reduced rank regression. DP1 had high consumption of beef and mutton, non-caloric drink and offal and low intake in tubers and roots, salty snacks, onion and spring onion, fresh fruits, desserts and nuts and seeds; DP2 had high intake of whole grains, Tibetan cheese, light-coloured vegetables and pork and low intake of sugar-sweetened beverages, whole-fat dairy products and poultry. Individuals in the highest tertile of DP1 showed higher risks of prediabetes (OR 95 % CI) 1·35 (1·05, 1·73) and T2D 1·36 (1·05, 1·76). The highest tertile of DP2 exhibited an elevated risk of T2D 1·63 (1·11, 2·40) in full adjustment.
Conclusion: Abdominal adiposity-related DP are positively associated with T2D. Promoting healthy eating should be considered to prevent T2D among Tibetan adults.

Background: The aim of this study was to assess the prevalence and clustering of cardiovascular disease (CVD) risk factors among ethnic minorities in plateau areas and their association with sociodemographic characteristics.
Methods: From September 2023 to January 2024, data were collected among ethnic minorities in plateau areas of Yunnan Province through face-to-face interviews. Ordered logistic regression and restricted cubic splines were used to assess the association between sociodemographic characteristics and the risk of clustering of risk factors.

spp., a key grass species for the ecological restoration of alpine degraded grasslands on the Qinghai-Tibet Plateau, often suffers from pest damage during its flowering and seed maturation stages, severely limiting the effectiveness of ecological restoration and the sustainable utilization of germplasm resources. This study focused on nine widely distributed species of in the Three River Source Region of Qinghai Province, systematically investigated the structure of arthropod communities and the spatiotemporal dynamics of pests, and developed an integrated pest management (IPM) strategy.
