A growing aging population is associated with increasing incidences of aging-related diseases and socioeconomic burdens. Hence, research into healthy longevity and aging is urgently needed. Longevity is an important phenomenon in healthy aging. The present review summarizes the characteristics of longevity in the elderly population in Bama, China, where the proportion of centenarians is 5.7-fold greater than the international standard. We examined the impact of genetic and environmental factors on longevity from multiple perspectives. We proposed that the phenomenon of longevity in this region is of high value for future investigations in healthy aging and aging-related disease and may provide guidance for fostering the establishment and maintenance of a healthy aging society.

“…Bama has typical karst landforms, and limestone rocky mountain and hilly sandstone belts comprise most of the landscape. The hilly sandstone and limestone rocky mountain belts account for ~69% and ~30% of the total karst landform in the area [ 10 ]. However, the long-lived population is distributed mainly in the limestone rocky mountain belt.…”

In 2021, the proportion of centenarians was approximately 5.7 times higher than the international standard . The exceptional longevity observed in Bama is closely associated with its superior local geographical environment and food habits, especially foods derived from Bama hemp products, such as hemp seed oil, hemp porridge, hemp protein powder, and hemp tea …”

Bama County is a world-famous longevity county in the Guangxi Province, China. Bama hemp is a traditional seed used in hemp cultivation in the Bama County. The seeds contain abundant unsaturated fatty acids, particularly linoleic acid (LA) and linolenic acid in the golden ratio. These two substances have been proven to be related to human health and the prevention of various diseases. However, the seed development and seed oil accumulation mechanisms remain unclear. This study employed a combined analysis of physiological, transcriptomic, and metabolomic parameters to elucidate the fatty acid formation patterns in Bama hemp seeds throughout development. We found that seed oil accumulated at a late stage in embryo development, with seed oil accumulation following an "S″-shaped growth curve, and positively correlated with seed size, sugar content, protein content, and starch content. Transcriptome analysis identified genes related to the metabolism of LA, α-linolenic acid (ALA), and jasmonic acid (JA). We found that the FAD2 gene was upregulated 165.26 folds and the FAD3 gene was downregulated 6.15 folds at day 21. Metabolomic changes in LA, ALA, and JA compounds suggested a competitive relationship among these substances. Our findings indicate that the peak period of substance accumulation and nutrient accumulation in Bama hemp seeds occurs during the midstage of seed development (day 21) rather than in the late stage (day 40). The results of this research will provide a theoretical basis for local cultivation and deep processing of Bama hemp.

“…In this study, we focused on the allocation of health resources in Guangxi, the only ethnic minority region in Southwest China, which has the largest population of Zhuang and Yao people in the world. Although Guangxi is famous for its scenery of Guilin and the longevity of its Bama population [10,11], it is an underdeveloped region with large differences in economic development between urban and rural areas. Public health researchers have focused on the remarkable heterogeneity in the spatial distribution of life expectancy [11,12] and many diseases [13][14][15] in Guangxi.…”

Background The inequitable distribution of health resources causes disparities in people's access to healthcare services, impacting residents’ health status and quality of life. As a result, the allocation of health resources has become a critical concern for governments when formulating healthcare policies. China is a developing country with uneven development among cities and rural areas, which lead the problem of inequity in health resources is noticeable, especially in less developed areas. Hence,we aimed to explore the spatial distribution of the average number of physicians and hospital beds in Guangxi and used spatial models to analyse the impact of economic, demographic and altitude factors on the distribution of health resources. These findings may provide a basis for the government to improve health policies. Methods We described the spatial patterns of the number of hospitals (NH), the number of hospital beds per 10,000 people (NHB), the number of practising physicians per 10,000 people (NPP), in Guangxi. Then, we explored the economic and demographic factors that may influence the spatial distribution of NHB and NPP through the geographically weighted regression (GWR) and multiscale geographically weighted regression (MGWR) models. Results Guangxi’s NH (Moran's I = 0.127, p = 0.006), NHB (Moran's I = 1.363, p = 0.001), and NPP (Moran's I = 1.289, p < 0.001) exhibited significant autocorrelation and heterogeneity in spatial distribution, significantly clustering and forming hotspots in Nanning, Liuzhou, Guilin and Wuzhou. The MGWR model showed spatial regression of NHB with the proportion of population ≥ 60 years old (EV = 0.337, p = 0.001), years of schooling (EV = 0.409, p = 0.002), general public income (EV = 0.228, p = 0.023) and average elevation (EV = 0.225, p = 0.042), while NPP was related to population density (EV = 0.230, p = 0.009), proportion of population ≥ 60 years old (EV = 0.250, p = 0.003), total social consumption (EV = 0.241, p = 0.010), etc. There were significant spatial regression relationships between GDP per capita (EV = 0.324, p < 0.001) and the proportion of urban dwellers (EV = 0.172, p = 0.033). Conclusions The spatial heterogeneity of healthcare resources in Guangxi is related to the enqual development of its socioeconomic, culture and population and is affected by topographical factors. The healthcare resources in Guangxi are clustered in areas with a relatively good degree of social development, such as Nanning, Liuzhou, Guilin and Wuzhou, with both absolute and relative deficiencies and with different factors influencing the number of beds per capita and the number of doctors per capita. Moreover, feasible ways to meet the demand for medical resources in different regions should be explored.
