To investigate the current status of fertility intentions among married women of childbearing age in Hebei Province under the background of the three-child policy, and to analyze the influencing factors of fertility support on married women of childbearing age’s fertility intention.

A random cluster sampling method was used to select married women of childbearing age in Hebei Province as the respondents in July 2023, and a self-designed questionnaire was used for the survey. Multinomial logistic regression was used to analyze the influencing factors of fertility intentions among married women of childbearing age.

A total of 1 200 questionnaires were distributed and 1104 valid questionnaires were collected, with a valid recovery rate of 92%. Among the survey subjects, 222 people (20.1%) had no intention of fertility/re-fertility, 263 people (23.8%) intended to have 1 child, 545 people (49.4%) intended to have 2 children, and 74 people (6.7%) intended to have 3 children or more. The results of multinomial logistic regression analysis showed that age, ethnicity, occupation, and residence area were influencing factors of fertility intentions. In terms of fertility support, time support, monthly childcare expenses, maternal care, and economic support were influencing factors of fertility intentions among married women of childbearing age.

The fertility intentions of married women of childbearing age are relatively low, and the intention of having three children is still at a low level. Actively providing fertility support and policies that encourage the fertility intentions of married women of childbearing age, and creating a good fertility environment, will help to enhance the fertility intentions of married women of childbearing age.

To analyze the myopia of middle school students in Heilongjiang Province in 2022, and to provide scientific basis for the development of myopia prevention strategies and measures.

99 114 middle school students in Heilongjiang Province in 2022 were selected to carry out a special survey on health risk behaviors. Their visual acuity and diopter were examined by using a 5-meter standard logarithmic visual acuity chart and desktop optometer. Binary Logistic regression was used to analyze the factors affecting myopia of students.

The total myopia rate of middle school students was 72.44%, including 70.50% junior high school students, 76.91% senior high school students and 64.47% vocational high school students. The myopia rate of students in urban area was higher than that in suburban county. The myopia rate of girls was higher than that of boys. Binary logistic regression analysis showed that: female students (OR=1.38, 95%CI: 1.35-1.43), frequently or always switching seats(OR=1.20, 95%CI: 1.15-1.25), spending more than 2 hours reading and writing after school every day(OR=1.11, 95%CI: 1.07-1.14), spending more than 2 hours a week attending cultural tutoring classes(OR=1.07, 95%CI: 1.03-1.11), parents often or always reminding them to pay attention to their reading and writing posture(OR=1.14, 95%CI: 1.10-1.19), and spending more time using the computer every day(h)≥ 2(OR =1.19, 95%CI: 1.24-1.45), using of mobile electronic devices in the past week(OR=1.11, 95%CI: 1.06-1.16), how often close range eye rest occurs(h)≥ 1(OR=1.11, 95%CI: 1.08-1.15), average daily indoor sitting time(h)≥ 8(OR=1.15, 95%CI: 1.12-1.19) are risk factors for myopia; Suburban counties(OR=0.95, 95%CI: 0.92-0.98), frequently adjusting the height of desks and chairs according to one’s own height(OR=0.94, 95%CI: 0.91-0.97), engaging in outdoor activities during breaks(OR=0.91, 95%CI: 0.89-0.94), having eyes more than 33 cm away from books while reading and writing(OR=0.84, 95%CI: 0.81-0.88), watching TV for≥2(OR=0.84, 95%CI: 0.80-0.88), and having outdoor activity time during the day(h)≥ 2(OR=0.93, 95%CI: 0.90-0.97), average daily sleep time(h)≥ 8(OR =0.80, 95%CI: 0.78-0.83) are protective factors for myopia.

Myopia is related to various factors such as residential area, gender, lifestyle, and behavioral habits.

To analyze the mediating effect of depressive symptoms between unhealthy lifestyle and body mass index (BMI), and to provide a reference basis for the prevention of common diseases among adolescents.

In 2023, 88, 594 students were selected by random stratified, class-based cluster sampling method from 12 municipalities in Inner Mongolia (103 counties) for questionnaire survey, to describe the basic demographic characteristics of the students, to explore the correlation between unhealthy lifestyle, depressive symptoms and BMI, and to establish the mediation effect model by using the PROCESS macro program in SPSS 26.0.

The number of detections of unhealthy lifestyle was 85 866, with a detection rate of 96.92 percent; the number of detections of abnormal BMI was 32 078, with a detection rate of 36.21 per cent; and the number of detections of depressive symptoms was 19, 356, with a detection rate of 21.85 per cent. The results showed that the mediating effect value of depressive symptoms on unhealthy lifestyle and body mass index was 0.0770, 95%CI: 0.0513-0.1027, and the mediating effect accounted for 11.35% of the total effect, which indicated that unhealthy lifestyle could mediate the increase of BMI through depressive symptoms.

Adolescents can prevent abnormal body mass index by improving unhealthy lifestyles, and they can also improve the occurrence of depressive symptoms and thus maintain a normal body mass index.

To investigate the quality of statistical reporting in publications from general medical journals and analyze the influencing factors.

A random sample of 480 original research articles published in 2010 and 2020 was selected from two Medline journals and six Chinese core journals in the field of medicine and health. The quality of statistical reporting was evaluated using a self-developed checklist based on the SAMPL guidelines, ICMJE recommendations, CONSORT, STROBE, and other relevant standards, followed by an analysis of influencing factors.

The overall quality score for statistical reporting in the surveyed general medical journals was 40.0±8.6. The scores for different statistical aspects were as follows: statistical design (43.2±6.8), statistical description (67.0±24.3), t-test (23.6±17.5), ANOVA (26.8±17.2), chi-square test (24.2±13.7), rank-sum test (45.5±18.4), correlation analysis (41.9±13.2), regression analysis (40.5±14.8), and survival analysis (45.6±14.9). Univariate analysis indicated that the overall quality score for statistical reporting in articles published in 2020 was higher than that in 2010 (35.8±7.4 vs. 44.3±7.5, t=-12.510, P<0.001). Multilevel modeling showed that the indexing system, research field, and publication year were the main factors influencing the overall score. Compared to Medline-indexed journals, the overall scores were lower for Chinese core journals. Articles focusing on non-human subjects had lower scores compared to those involving human subjects. Additionally, the overall scores for articles published in 2020 were higher than those in 2010.

The quality of statistical reporting in general medical journals in China has improved over the past decade, but there remains substantial room for further improvement. It is recommended to enhance the promotion of relevant reporting standards.

To explore potential classifications and characteristics of mental health literacy among HIV-positive men who have sex with men.

From November 2023 to January 2024, 226 HIV-positive MSM in a tertiary hospital in Nanjing were selected by the convenience sampling method and were investigated by general information questionnaire and multicomponent mental health literacy scale. Latent class analysis and multivariate logistic regression analysis were used to explore the categorical characteristics and influencing factors of mental health literacy in this group.

The mental health literacy characteristics of HIV-positive MSM could be classified into low literacy group (22.1%), resource deficient group (38.1%), and high literacy group (39.8%). Multiple logistic regression analysis showed that patients aged 18-34 (OR=5.573, 95%CI=1.020-30.449) were more likely to be in the resource deficient group than the low literacy group, and those who had participated in learning mental health skills (OR=0.126, 95%CI=0.033-0.476) were more likely to be in the high literacy group. Compared with the high literacy group, patients with literacy level of junior high school or below (OR=15.992, 95%CI=2.036-125.591), high school or junior college (OR=2.805, 95%CI=1.098-7.166), length of time to diagnosis of HIV infection <1 year (OR=8.440, 95%CI=1.628-43.742), and with comorbidities (OR=6.619, 95%CI=1.077-40.663) were more likely to be in the low literacy group; and patients with a monthly per capita family income of <3000 yuan (OR=6.241, 95%CI=1.088-35.814) were more likely to be in the resource deprived group.

There are three potential categories of mental health literacy among HIV-positive MSM. In the future, targeted intervention strategies should be developed to improve the level of their mental health literacy and further improve their mental health according to this group’s different category characteristics and influencing factors.

To explore the minimum clinically important difference (MCID) of peptic ulcer scale QLICD-PU (V2.0) among the System of quality of life instruments for chronic diseases.

Using convenience sampling, the questionnaire was administered from March 2013 to August 2014 using the QLICD-PU (V2.0) scale, and the MCIDs were calculatedusing the anchor-based and distribution-based methods, respectively, and analyzed to compare the MCIDs developed by taking the mean, taking the minimum, and taking the maximum methods.

The MCIDs of physical functioning (8.53), psychological functioning (8.45), social functioning (7.61), general module (7.05), specific module (8.82), and overall scale (7.53) obtained by taking the mean method; the MCIDs obtained by taking the minimum method were 5.25, 5.78, 6.16, 4.19, 7.18 and 4.09, respectively; the MCID obtained by taking the maximum method were 11.99, 12.05, 10.09, 9.48, 10.99 and 11.04, respectively.

In this paper, MCID was formulated by using various methods and criteria, which can be chosen by the users according to the situation. MCID can be used to assess the clinical efficacy of patients with peptic ulcers for the application of quality of life. The MCID values formulated can be validated further by clinical practice in subsequent studies.

To investigate the knowledge of monkeypox among men who have sex with men (MSM) in Central Jiangsu Province in 2023, and to provide evidence for the prevention and treatment of monkeypox in this population.

The monkeypox questionnaire designed by Jiangsu Provincial Center for Disease Control and Prevention was used to investigate HIV Voluntary Counseling & Testing (VCT) clinic and social organizations in central Jiangsu Province. Excel 2010 and SPSS19.0 software were used to organize and analyze the data. Also, univariate and multivariate Logistic regressions were used to analyze the factors affecting the awareness rate of monkeypox knowledge. χ² test was used to compare the difference of concern degree of monkeypox among people with different characteristics.

A total of 1 290 valid questionnaires were collected. The majority were aged from 26 to 50 years, accounting for 65.04% (839/1 290). The majority of the students were college students, bachelor students or above, accounting for 64.26% (829/1 290). The awareness rate of monkeypox was 26.12%, and the complete awareness rate was 15.27%. The results of multivariate Logistic regression analysis showed that the related factors with higher awareness rate of monkeypox included Taizhou (OR=6.710, 95%CI: 4.309-10.447), high school/technical school (OR=2.461, 95%CI: 1.270-4.769), college (OR=2.515, 95%CI: 1.311-4.825), bachelor’s degree or above (OR=2.253, 95%CI: 1.184-4.288), concerned about monkeypox epidemic and related situation (OR=1.684, 95%CI: 1.188-2.387) (all P < 0.05). The correct rates of monkeypox symptoms, preventive measures and transmission routes were 30.78%, 42.25% and 27.75%, respectively. 1 186 people (91.94%) paid attention to monkeypox epidemic and prevention knowledge from WeChat, Weibo and other network new media. MSM with different regions (χ²=65.348, P<0.001), age groups (χ²=19.422, P=0.001), educational levels (χ²=31.447, P<0.001), marital status (χ²=11.162, P=0.025), results of the latest HIV test (χ²=37.793, P<0.001), sexual orientations (χ²=39.441, P<0.001), whether they had sexual contact with the same sex in the last 6 months (χ²=29.329, P<0.001), and whether they had sexual contact with overseas personnel (χ²=29.199, P<0.001), paid different attention to monkeypox information, and the differences were statistically significant.

The awareness rate of MSM monkeypox knowledge in central Jiangsu Province is low, and the accuracy rate of monkeypox symptoms, transmission routes and prevention and control measures are low. Therefore, it is necessary to publicize monkeypox symptoms and transmission routes through new media such as WeChat, Weibo, Douyin and Baidu in the later stage.

To explore the prevalence and influencing factors of depression among the elderly in rural areas of Sichuan Province.

By using the method of multi-stage sampling, a questionnaire survey was conducted among 606 rural elderly persons in Sichuan from July to August, 2022. Chi-square test and multivariate logistic regression analysis were used to explore the influencing factors of depression.

The average score of depression in the rural elderly was (3.79± 3.21) points, 85 people had depressive symptoms, and the prevalence rate of depressive symptoms was 14.0%. Multivariate logistic regression analysis showed that not seeking medical treatment due to economic difficulties in the past year (OR=10.140, 95%CI: 3.347-30.716), hospitalization in the past year (OR=5.229, 95%CI: 2.789-9.801), self-rated health fair or below( poor self-rated health: OR=20.301, 95%CI: 7.666-53.761; fair self-rated health: OR=5.912, 95%CI: 2.729-12.807) and childless (OR=8.495, 95%CI: 1.747-41.313) were risk factors for depressive symptoms in the rural elderly (P<0.05). Living with a spouse (OR=0.321, 95%CI: 0.116-0.888) and high social support (OR=0.505, 95%CI: 0.260-0.982) were protective factors for depressive symptoms in rural elderly (P<0.05).

The depression situation of the elderly in rural areas of Sichuan Province is worrying, which needs to be paid special attention and early intervention, especially for the rural elderly with economic difficulties, poor health status, no children or living alone.
