Addressing the public health concerns of physical inactivity, low levels of fitness, and unhealthy weight among Chinese school-aged children

In China,sports and physical activity(PA)have traditionally been an integral part of school curricula to promote fitness and enhance healthy growth among children and adolescents.Three decades of economic reforms,however,have brought major changes in social,economic,and built environments that have resulted in concerns about the general health of the Chinese population due to accumulating epidemiologic evidence of increased levels of physical inactivity,high rates of obesity,and unhealthy diet.With the emergence of a progressively obesogenic environment,lack of safe and acces-

Importance must be attached to correcting unhealthy lifestyles in prevention and control of hypertension

Unhealthy Cooking and Prevalence of Tuberculosis in Indian Women: A Case Study

Unhealthy cooking is one of the major cause of mortality and morbidity and a risk factor for occurrence of tuberculosis among Indian women. India is the TB burden country in the world and accounts for nearly 20 percent of global burden of tuberculosis. The present study establishes the association between unhealthy cooking conditions (use of biomass fuels/chulhas, cooking in multipurpose room, Non-ventilated kitchen, living in kutcha/semi-pucca houses) and prevalence of tuberculosis in women. This study is based on primary sources of data collected through questionnaire interviews from 2101 women respondents belonging to different income categories from Aligarh city. The study examines the socio-economic characteristics, cooking conditions, monitoring of indoor air quality of different types of kitchen locations using different types of fuels. Symptomatic linkages of tuberculosis with type of fuel use, kitchen locations and house type were analysed. The results show that the women using biomass fuels/chulhas cooking in non-ventilated kitchens and multipurpose room, living in kutcha/semi pucca houses were most prone to tuberculosis.

Analysis of factors related to postpartum depression in pregnancyinduced hypertension syndrome patients and construction and evaluation of nomograms

BACKGROUND It is positive to integrate and evaluate the risk factors for postpartum depression in patients with pregnancy-induced hypertension syndrome and to detect highrisk patients as early as possible,which has application value for the clinical development of personalized prevention programs and prognosis of patients.AIM To analyze factors related to postpartum depression in patients with pregnancyinduced hypertension and construct and evaluate a nomogram model.METHODS The clinical data of 276 patients with pregnancy-induced hypertension admitted to Huzhou Maternity and Child Health Care Hospital between January 2017 and April 2022 were retrospectively analyzed.We evaluated the depression incidence at 6 wk postpartum.The depression group included patients with postpartum depression,and the remainder were in the non-depression group.Multivariate logistic regression analysis and the LASSO regression model were applied to analyze the factors related to postpartum depression in patients with pregnancyinduced hypertension.After that,a risk prediction model nomogram was constructed and evaluated.RESULTS Multivariate logistic regression analysis showed that vitamin A deficiency(VAD)during pregnancy and puerperium,family history of hypertension,maternal intestinal flora imbalance,eicosapentaenoic acid(EPA),and docosahexaenoic acid(DHA)were independent risk factors for postpartum depression in patients with pregnancy-induced hypertension(P<0.05).We constructed the nomogram model based on these five risk factors.The area under the curve,specificity,and sensitivity of the model in predicting postpartum depression in patients with pregnancy-induced hypertension was 0.867(95%confidence interval:0.828–0.935),0.676,and 0.889,respectively.The average absolute error was 0.037(Hosmer-Lemeshow testχ2=10.739,P=0.217).CONCLUSION VAD during pregnancy and puerperium,family history of hypertension,maternal intestinal flora imbalance,EPA,and DHA affect postpartum depression in patients with pregnancy-induced hypertension.

Overweight, obesity, and screen-time viewing among Chinese school-aged children: National prevalence estimates from the 2016 Physical Activity and Fitness in China—The Youth Study

Purpose: This study presents the most recent estimates of prevalence of overweight, obesity, and screen-time viewing among Chinese school-aged children. Demographic differences in these estimates between sexes and resident locales were also examined.Methods: Cross-sectional analyses of 116,615 Chinese school children 9 to 17 years of age who participated in the 2016 Physical Activity and Fitness in China—The Youth Study project. Outcomes were the prevalence of children's overweight(85 th ≤ body mass index(BMI) < 95 th percentile) and obesity(BMI ≥95 th percentile)(defined by the Working Group on Obesity in China) and not meeting screen-time viewing recommendations("not meeting" was defined as more than 2 h per day of viewing activities after school). Analyses were conducted on the whole sample and by school grade cohorts(primary, junior middle, and junior high schools), sex, and residence locales(urban, rural).Results: Overall, 14.4%(95% confidence interval(CI): 13.8%–15.0%) of children and adolescents were overweight, 11.9%(95%CI: 11.0%–13.0%) were obese, and 36.8%(95%CI: 34.7%–38.9%) did not meet screen-time viewing recommendations. Across the 3-grade cohorts, boys were more likely to be obese than girls, and primary and junior middle school children living in urban areas were more likely to be obese than those living in rural areas. Primary and junior middle school boys were less likely to meet screen-time recommendations than girls, and junior high school children living in urban areas were less likely to meet screen-time recommendations than school children of the same grades living in rural areas.Conclusion: In 2016, the prevalence of obesity among Chinese school children was about 12%, and about 37% of them did not meet screen-time viewing recommendations. The prevalence of obesity and sedentary behavior was generally higher among boys than among girls, and it was higher for children living in urban areas than for those living in rural areas.

New obesity classification criteria as a tool for bariatricsurgery indication

Obesity plays relevant pathophysiological role in the development of health problems, arising as result of complex interaction of genetic, nutritional, and metabolic factors. Due to the role of adipose tissue in lipid and glucose metabolism, and low grade inflammation, it is necessary to classify obesity on the basis of body fat composition and distribution, rather than the simply increase of body weight, and the Body Mass Index. The new term of adiposopathy(‘‘sick fat'') clearly defines the pathogenic role of adipose tissue. Four phenotypes of obese individuals have been described:(1) normal weight obese(NWO);(2) metabolically obese normal weight;(3) metabolically healthy obese; and(4) metabolically unhealthy obese or "at risk" obese. Moreover, sarcopenic obesity has been related to all the phenotypes. The category of normal weight lean, represented by metabolically healthy normal weight has been classified to distinguish from NWO. It is crucial to recommend a bariatric surgery taking into account adiposopathy and sick fat that occurs with the expansion of fat mass, changing the inflammatory and metabolic profile of the patient. Body fat percentage and genetic polymorphism have to be evaluated to personalize the best bariatric surgery intervention.

Nutritional Attributes as Predictors of Coronary Heart Disease

Background: Diet is an important modifiable risk factor for coronary heart disease (CHD). However, the influence of some groups of food intake on CHD has shown inconsistent findings. Objectives: This study aimed to identify the relation of the dietary habits, Vitamin D, serum lipids, and anthropometric measures of the participants with CHD. Methods: A retrospective case-control study was conducted at Al-Remal Clinic, Gaza City. The study included 50 cases of symptomatic CHD and 50 controls, chosen by convenience sampling method. Data were collected by direct methods that included measurement of serum levels of lipids and Vitamin D, and indirect methods using a structured interview questionnaire. Results: The mean of servings per day of fruits and vegetables was lower in CHD patients than controls (P = 0.004, and P = 0.001, respectively). Vitamin D deficiency prevailed in CHD patients (odds ratio, 3.78;95% confidence interval, 1.65 - 8.65). The mean serum level of triglycerides was higher among cases (P = 0.02), while the mean of high-density lipoprotein cholesterol was lower in CHD patients (P = 0.001). Waist circumference (mean) was higher among cases (P = 0.01). Conclusion: Traditional risk factors including unhealthy diet, and Vitamin D deficiency could be associated with the development of CHD.

Understanding the Lifestyle Correlates with Chronic Constipation and Self-Rated Health

The objective of this study is to evaluate the healthy and unhealthy behaviors as risk factors for chronic constipation and self-rated health status. Eight hundred tenth students enrolled from a university in Miaoli city, Taiwan. Chronic constipation was assessed using Chinese questionnaire. Information of unhealthy and healthy lifestyles was interviewed by constructed questionnaire. Thirty-six percentage of university students were assessed as chronic constipation. Using multivariate logistic regression adjusted for age, sex, race and BMI, we found chronic constipation significantly correlated with frequency of consumption from snack, fast food, fried food, daily consumption of water, physical activity and junk food used as regular food. Moreover, these unhealthy behaviors significantly correlated with self-rated health status. Students with chronic constipation had poor self-rated health status. It is urgent to create healthy behaviors to reduce the risk for chronic constipation or upgrade self-rated health status in university students.

Organizing and Disorganizing Resonances of Microtubules, Stem Cells, and Proteins Calculated by a Quantum Equation of Coherence

Conformational states of microtubules and proteins have typical spatial-spectral arrangements of atoms, called spatial coherence, that are characteristic for building, homeostasis, decay, and apoptosis. Microtubules show a principle of a self-organizing-synergetic structure called a Fröhlich-Bose-Einstein state. The spatial coherence of this state can be described by a toroidal quantum equation of coherence. In this space, microtubules and proteins have typical discrete frequency patterns. These frequencies comply with two proposed quantum wave equations of respective coherence (regulation) and decoherence (deregulation), that describe quantum entangled and disentangled states. The proposed equation of coherence shows the following typical scale invariant distribution of energy: En = ħωref 2q3m. The proposed model supports quantum entanglement and is in line with the earlier published models of Fröhlich, Davydov, and Chern. A meta-analysis shows a semi-harmonic scale-invariant pattern for microtubules, stem cells, proteins, and EEG- and MEG-patterns. A fit has been found for about 50 different organizing frequencies and 5 disorganizing frequencies of measured microtubule frequencies that fit with the calculated values of the proposed quantum equations, which are positioned in a nested toroidal geometry. All measured and analysed frequencies of microtubules comply with the same energy distribution found for Bose-Einstein condensates. The overall results show a presence of an informational quantum code, a direct relation with the eigenfrequencies of microtubules, stem cells, DNA, and proteins, that supplies information to realize biological order in life cells and substantiates a collective Fröhlich-Bose-Einstein type of behaviour and further support the models of Tuszynski, Hameroff, Bandyopadhyay, Del Giudice and Vitiello, Katona, Pettini, and Pokorny.

Task 1 There is a discussion among members of our school district. It is about putting soda machines in community schools. Those in favor point to the money the schools will receive. Others think that it is unhealthy for students. This is because soda is almost made up of sugar.

Scrutinizing the causal relationship between schizophrenia and vitamin supplementation:a Mendelian randomization study

Objective: Observational studies have reported malnutrition and vitamin deficiency in patients with schizophrenia (SZ), which can lead to serious metabolic syndromes and decrease anti-psychiatric drug outcomes. Whereas, vitamin intake along with psychiatric medication can enhance the medication outcomes. However, it is still unknown if SZ induces vitamin deficiency. Herein, we conduct the Mendelian randomization analysis to explore the causal relationship between schizophrenia and vitamins supplementation.Methods: We retrieved the genome-wide summary statistical data for schizophrenia from recent SZ GWAS data (43,175 cases and 65,166 controls) and vitamins supplementation GWAS data from Neale’s GWAS datasets (more than 337,000 samples from the European population) and performed a two-sample Mendelian randomization analysis to determine the causal association of SZ with vitamin supplementation, in addition, we conduct the sensitivity analysis to obtain reliable results and remove confounding bias.Results: SZ have causal relationships with vitamins A, B, C, D, and E (SZ/vitamin A: β = 0.002, se= 0.001, 95% confidence interval (CI): 0.001 to 0.004,P= 1.41E-05, heterogeneityP= 0.4486;SZ/vitamin B: β= 0.004, se= 0.001, 95% CI: 0.002-0.005,P= 7.0E-05, heterogeneityP= 0.2217;SZ/vitamin C: β= 0.004, se= 0.001, 95% CI: 0.002-0.007,P= 0.001, heterogeneityP= 0.1349;SZ/vitamin D: β= 0.003, se= 0.001, 95% CI: 0.002-0.005,P= 0.001, heterogeneityP= 0.433;SZ/vitamin E: β= 0.003, se= 0.001, 95% CI: 0.002-0.005,P= 5.0E-05, heterogeneityP= 0.1382).Conclusion: Our findings suggest that vitamin levels and supplementation should be carefully controlled in patients with SZ, which in turn may enhance the therapeutic effects of antipsychotic drug treatments.
