Introduction: Suicide is an important public health concern in China. We examined suicide mortality by place, sex, and age group from 2010 to 2021 to identify and quantify significant suicide mortality changes in China.

Methods: We retrieved age-standardized and age-specific suicide mortality rates by place (urban vs. rural) and sex from the Chinese Health Statistical Yearbook and population data from the 2010 and 2020 Chinese National Population Census. Line graphs were used to demonstrate trends in suicide mortality. Joinpoint regression models were fitted to detect the time periods experiencing significant suicide mortality changes, and average annual percent change (AAPC) and annual percent change were reported to quantify changes in suicide mortality from 2010 to 2021.

Results: The overall age-standardized suicide mortality rate decreased from 10.88 to 5.25 per 100,000 population between 2010 and 2021 (AAPC=-5.3%, 95% confidence interval: -6.5%, -4.0%). Similar reductions in suicide mortality were observed for both males and females, as well as in urban and rural settings during this period. From 2010 to 2021, significant declines in suicide mortality were observed among the three older age groups (25-44 years, 45-64 years, and 65 years or above), while a substantial increase was noted in the youngest age group (5-14 years). No significant change was found in suicide mortality rates for the 15-24 year age group. Subgroup analyses based on location and sex revealed consistent findings.

Conclusion: The findings of this study suggest a probable overall success of suicide prevention efforts in China over the past decade. However, the recent increase in suicide mortality among children aged 5-14 years calls for the attention of injury researchers, policymakers, and public health practitioners.

What is already known about this topic?: Childhood obesity has been linked to adverse health outcomes during both childhood and adulthood. An accurate understanding of children's weight status by primary caregivers is essential for effective weight management strategies.

What is added by this report?: The data utilized in this study were obtained from the 2021 Nutrition Improvement Program for Rural Compulsory Education Students in China. It was found that over one-third of primary caregivers underestimated their children's weight status, and more than half of the primary caregivers of overweight or obese children underreported the weight status of those children. A low level of agreement was observed between primary caregivers' perceptions of their children's weight status and the actual weight status.

What are the implications for public health practice?: There is a relatively higher underestimation of children's weight in China, which necessitates more effective strategies to enhance the primary caregivers' perception of their children's weight status, especially in primary caregivers of males, younger children and children in urban areas.

What is already known about this topic?: Malnutrition continues to be the primary cause of delayed growth and development among students in economically disadvantaged rural areas of China. Ensuring adequate and appropriate dietary intake is crucial for promoting the healthy growth of these students.

What is added by this report?: In rural areas of central and western regions in China, the weekly consumption frequencies of meat, eggs, milk, legumes, fruits, and vegetables in 2021 were higher than those in 2019. However, the consumption levels remained relatively low in economically underdeveloped rural areas in 2021.

What are the implications for public health practice?: Understanding the frequency of food consumption among students can provide a solid evidence base for the development of policies and strategies aimed at controlling and preventing malnutrition.

What is already known about this topic?: Physical fitness is closely associated with children's development. Limited research has been published on the changes in physical fitness among Chinese children during the implementation of the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES).

What is added by this report?: This research utilized data from the NIPRCES between 2013 and 2021 to examine alterations in children's physical fitness levels. Over this period, there was a significant increase in the number of rope skipping counts among children. In 2021, variations in these counts were observed, which depended on factors such as age, gender, geographic location, and region.

What are the implications for public health practice?: Physical fitness has been linked to a multitude of non-communicable diseases. Enhanced nutritional measures for children lead to significant improvements in their overall physical fitness, as evidenced by NIPRCES findings. It is crucial for policymakers to implement comprehensive interventions aimed at promoting and advancing children's physical fitness.

What is already known about this topic?: Inconsistent results have been reported on the association between periconceptional folic acid only (FAO) or multiple micronutrients containing folic acid (MMFA) supplementation and the risk of gestational diabetes mellitus (GDM) in previous research.

What is added by this report?: In a prospective cohort study conducted among pregnant women in Haidian District, Beijing Municipality, it was observed that those who took MMFA demonstrated a higher likelihood of developing GDM in comparison to those who consumed FAO periconceptionally. Interestingly, the increased risk for GDM in pregnant women supplemented with MMFA compared to FAO was primarily due to changes in fasting plasma glucose.

What are the implications for public health practice?: It is highly recommended that women prioritize the use of FAO in order to yield potential benefits in the prevention of GDM.

What is already known about this topic?: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to evolve, the clinical manifestations resulting from different SARS-CoV-2 variants may demonstrate significant variation.

What is added by this report?: We conducted a comparative analysis of the clinical features associated with SARS-CoV-2 Omicron subvariants BF.7.14 and BA.5.2.48 infections. The results of our study indicate that there are no substantial differences in clinical manifestations, duration of illness, healthcare-seeking behaviors, or treatment between these two subvariants.

What are the implications for public health practice?: Timely identification of alterations in the clinical spectrum is crucial for researchers and healthcare practitioners in order to enhance their comprehension of clinical manifestations, as well as the progression of SARS-CoV-2. Furthermore, this information is beneficial for policymakers in the process of revising and implementing appropriate countermeasures.
