Calcium, magnesium, sodium, and potassium are essential macroelements for human health. While China has implemented comprehensive policies to enhance nutritional and health status, understanding current macroelement intake patterns among Chinese adults remains crucial. This study analyzed adults participating in the China Development and Nutrition Health Impact Cohort Survey (2022–2023), which continues the China Health and Nutrition Survey (CHNS). Using consecutive 3-day 24-hour dietary recall combined with household weighing methods, we calculated intake levels of calcium, magnesium, sodium, and potassium. Results revealed median daily intakes of 288.3, 228.9, 4,182.4, and 1,397.6 mg/d for these macroelements respectively, with a median Na/K ratio of 3.0. Analysis showed that 96.1% of adults had calcium intake below the estimated average requirement (EAR), 64.4% had magnesium intake below the EAR, 81.9% had potassium intake below the adequate intake (AI), and 89.4% exceeded the Prevention of non-communicable diseases intake level (PI-NCD) for sodium. Urban areas consistently demonstrated better macroelement intake patterns compared to rural areas. These findings indicate the need for a comprehensive approach encompassing enhanced nutrition education, promotion of healthy eating habits, strengthened food supply chains, and improved access to nutritious foods to elevate overall nutrition status and reduce urban-rural disparities.

The global prevalence of insufficient physical activity (PA) among adults has shown an upward trend in recent years. In China, the prevalence of insufficient PA among adults increased to 22.3% by 2018, with sedentary behavior becoming increasingly prevalent. In response, the Chinese government has implemented various measures to reduce insufficient PA levels and sedentary behavior while improving national fitness. To assess the current status of PA and sedentary behavior in China, we analyzed data from the twelfth China Health and Nutrition Survey (CHNS) conducted across ten provincial-level administrative divisions (PLADs) between 2022 and 2023. PA and sedentary behavior data were collected through tablet-based face-to-face interviews from 10,103 participants aged 18 years and above. The study found that 85.7% and 70.9% of adults met the Physical activity guidelines (PAGs) recommendations of 150 minutes and 300 minutes, respectively. While occupational PA remained the primary domain, domestic PA and leisure time PA (LTPA) followed at 16.9% and 14.2% respectively, showing minimal difference between these secondary domains. Screen-based activities emerged as the predominant form of sedentary behavior, with approximately 25% of Chinese adults spending more than 6 hours daily in sedentary activities. Given the inevitable progression of social change and rapid urbanization, increasing LTPA represents the most viable strategy for reducing physical inactivity rates. Further interventions are needed to reduce sedentary time while promoting LTPA participation, particularly among young residents and urban populations.

To analyze the trends in overweight and obesity among children and adolescents aged 6-15 years in the central and western regions of China, as covered by the Nutrition Improvement Programme for Rural Compulsory Education Students, from 2012 to 2023, stratified by region, gender, and age. This analysis aims to provide a scientific basis for the implementation of nutrition improvement policies. A multi-stage, stratified, random cluster sampling design was employed to select children and adolescents aged 6-15 years from rural areas across 22 provincial-level administrative divisions (PLADs) in central and western China from 2012 to 2023. Standardized measurements of height and weight were taken before breakfast in the morning according to the Anthropometric Methods for Population Health Surveillance (WS/T 424-2013). Overweight and obesity were determined based on the Overweight and Obesity in School-aged Children and Adolescents(WST 586-2018) criteria. The prevalence of overweight and obesity were analyzed by region, gender, and age. Segmented line regression was conducted using Joinpoint regression to identify significant changes in prevalence trends, with annual average percentage change (AAPC) and annual percentage change (APC) calculated to quantify the direction and magnitude of trends. The overall overweight prevalence increased from 8.0% in 2012 to 10.2% in 2023, with an annual average percentage change (AAPC) of 2.0%. The western region showed a higher increase in overweight (AAPC = 3.0%) compared to the central region (AAPC = 2.0%). Males exhibited a higher significant increase in overweight (AAPC=2.1%) compared to females (AAPC=2.0%). Age-specific analysis revealed that overweight prevalence ranged from 15.0% in 6-year-olds to 4.9% in 15-year-olds in 2012, and from 12.6% to 8.5% respectively in 2023. Significant increases were observed in age groups 9 (AAPC=2.3%) through 15 (AAPC=5.8%).The overall obesity prevalence rose from 3.0% to 8.7%, with an AAPC of 10.6%. The corresponding annual percentage changes (APCs) for the periods 2012-2016, 2016-2019, and 2019-2023 were 11.4%, -4.7% (P>0.05), and 22.8%, respectively. The western region demonstrated a higher significant increase in obesity(AAPC=11.8%) compared to the central region (AAPC=11.1%).Males showed a higher significant increase in obesity(AAPC=10.8%) compared to females (AAPC=10.3%). Age-specific analysis demonstrated that obesity prevalence ranged from 8.0% in 6-year-olds to 0.5% in 15-year-olds in 2012, and from 12.5% to 4.1% respectively in 2023. Significant increases were observed across all age groups, from age 6 (AAPC=4.7%) through age 15 (AAPC=21.9%). While addressing malnutrition, it is crucial to focus on the rapid increase in overweight and obesity among children in central and western rural areas. Policies should be tailored based on differing trends, adjusting measures accordingly to curb the expansion of overweight and obesity.

Physical activity (PA) and sedentary behavior (SB) are crucial determinants of both physical and mental health outcomes. However, large-scale studies using objective measurements of these behaviors have not been widely implemented across China. Based on World Health Organization guidelines, 56.8% of participants met the recommendation for moderate-to-vigorous physical activity (MVPA) by accumulating more than 150 minutes per week. Additionally, 37.3% adhered to the sedentary behavior guideline of less than 8 hours per day. However, only 2.7% of adults achieved compliance with both MVPA and SB recommendations simultaneously. This study provides novel insights into PA levels and SB patterns among Chinese adults using waist-mounted accelerometry. The observed trends of insufficient PA and excessive SB in this multi-provincial sample emphasize the urgent need for targeted interventions to promote physical activity and reduce sedentary time to foster healthier lifestyle behaviors.

Infectious diseases represent a major public health challenge in Sierra Leone, where public health laboratories play a crucial role in early detection, rapid response, and epidemic control. This study evaluated the capacity of public health laboratories (PHLs) in Sierra Leone following the implementation of the 2015 National Laboratory Strategic Plan to provide evidence-based recommendations for future laboratory system development. The mean comprehensive capacity score across 11 indicators for all PHLs was 71.0%, with significant inter-facility variation. High average scores were observed in organization and management (94.0%), transport and specimen referral (88.0%), and biosafety and waste disposal (81.0%). However, laboratory performance (59.0%), experimental technical training (60.0%), information management (62.0%), and laboratory infrastructure & equipment (63.0%) scored notably lower. The proportion of laboratory staff with advanced degrees, extensive experience (≥10 years), and specialized training in surveillance, field epidemiology & laboratory techniques, and bioinformatics was limited. While approximately 80% of staff demonstrated proficiency in basic laboratory operations, fewer than 24% were capable of performing tissue anatomy, sequencing primer design, and gene library creation. Continued investment in PHL capacity building in Sierra Leone is essential, with priority given to addressing the identified gaps.
