BACKGROUND Lifestyle diseases are the primary cause of death worldwide. The gradual growth of negative behavior in humans due to physical inactivity, unhealthy habit, and improper nutrition expedites lifestyle diseases. In this study, we develop a mathematical model to analyze the impact of regular physical activity, healthy habits, and a proper diet on weight change, targeting obesity as a case study. Followed by, we design an algorithm for the verification of the proposed mathematical model with simulated data of artificial participants. OBJECTIVE This study intends to analyze the effect of healthy behavior (physical activity, healthy habits, and proper dietary pattern) on weight change with a proposed mathematical model and its verification with an algorithm where personalized habits are designed to change dynamically based on the rule. METHODS We developed a weight-change mathematical model as a function of activity, habit, and nutrition with the first law of thermodynamics, basal metabolic rate (BMR), total daily energy expenditure (TDEE), and body-mass-index (BMI) to establish a relationship between health behavior and weight change. Followed by, we verified the model with simulated data. RESULTS The proposed provable mathematical model showed a strong relationship between health behavior and weight change. We verified the mathematical model with the proposed algorithm using simulated data following the necessary constraints. The adoption of BMR and TDEE calculation following Harris-Benedict’s equation has increased the model's accuracy under defined settings. CONCLUSIONS This study helped us understand the impact of healthy behavior on obesity and overweight with numeric implications and the importance of adopting a healthy lifestyle abstaining from negative behavior change.

Abstract Background: Lifestyle diseases are the leading cause of death worldwide. The gradual increase of negative behavior in humans because of physical inactivity, unhealthy habit, and improper nutrition expedites the growth of lifestyle diseases. Proper lifestyle management in the obesity context may help to reach personal weight goal or maintain a normal weight range with optimization of health behaviors (physical activity, diet, and habits). Objective: In this study, we develop a mathematical model to analyze the impact of regular physical activity, a proper diet, and healthy habits on weight change, targeting obesity as a study case. Followed by, we design an algorithm to verify our proposed model with simulated data and compare it with related proven models based on the defined constrains. Methods: We proposed a weight-change mathematical model as a function of activity, habit, and nutrition with the first law of thermodynamics, basal metabolic rate ( BMR ), total daily energy expenditure ( TDEE ), and body-mass-index ( BMI ) to establish a relationship between health behavior and weight change. Followed by, we verify the model with simulated data and compared it with related established models. In this study, we have used revised Harris-Benedict equations (HB) for BMR and TDEE calculation. Results: The proposed mathematical model showed a strong relationship between health behavior and weight change. We verified the mathematical model with a proposed algorithm using simulated data with defined constraints. The adoption of BMR and TDEE calculation following revised Harris-Benedict equations has beaten the classical Wishnofsky’s rule (3500 cal. ≈ 1 lb.) , and the models proposed by Toumasis et al., Azzeh et. Al., and Mickens et. al. with a standard deviation of ±1.829, ±2.006, ±1.85, and ±1.80, respectively. Conclusions: This study helped us to understand the impact of healthy behavior on weight change with mathematical implications and the importance of a healthy lifestyle. As a future research scope, we wish to use this model in a health eCoach system to generate personalized lifestyle recommendations to optimize health behaviors to accomplish personal weight goals.

The Impact

The global pandemic caused by the COVID-19 has profoundly changed the daily life of most of the world population. People with disabilities have been particularly affected by these changes, which often have accentuated their isolation and marginalization also due to greater difficulties in accessing healthcare services. People with disabilities have also been impacted in relation to their ability to participate in physical activity with even more adverse consequences for their quality of life and health. The aim of this study was to explore the impact of the COVID-19 pandemic on physical activity practice of people with disabilities and to understand the changes that caregivers have perceived for the participation in physical activity of this specific population. It emerged that, regardless of the type of disability, people with this condition experienced drastic reductions in their physical activity levels during the pandemic and in most cases did not have access to any type of remote guidance. Furthermore, a higher prevalence of sedentary behavior and negative changes in eating habits have been reported by the caregivers, highlighting the need for specific strategies and initiatives for people with disabilities to maintain healthy habits and a physically active lifestyle.

Multiple health behavior change (MHBC) interventions have great potential for enhancing health and well-being following cancer diagnosis and treatment. However, the characteristics and effects of MHBC interventions remain elusive for cancer survivors. The main purpose of this study was to evaluate the effectiveness of MHBC interventions on healthy eating and physical activity behaviors among cancer survivors. A secondary aim was to examine the effect of using a simultaneous and sequential design approach to MHBC (ie, changing both behaviors at the same time or one after the other). Randomized controlled trials reporting the impact of a MHBC intervention on both healthy eating and physical activity behaviors among cancer survivors were retrieved from MEDLINE, Cochrane Library, and PsycINFO. A total of 27 MHBC interventions were identified; most (92.6%) were designed to promote simultaneous change in both behaviors and assessed end-of-treatment effect among breast cancer survivors. MHBC interventions led by nurses or multidisciplinary teams showed the most compelling evidence for small to moderate improvement in both behaviors, with interventions that lasted ≥17 weeks more likely to improve both behaviors. This study identifies research priorities and provides preliminary evidence for clinical decision making and advancements in MHBC intervention design and delivery for clinical oncology.

Abstract Background: Pandemic caused by the COVID-19 virus brought tremendous changes in the lifestyle of adolescents, about which numerous studies have been published. Due to extended restrictions, long term impact should be investigated.Methods: This cross-sectional study enrolled 953 voluntary participants aged 14 to 21, from different regions of B&H. Participants were asked to complete an online 37-item survey, regarding socio-demographics, geographic, social characteristics, dietary and lifestyle habits, physical activity, including their consumption of dietary, vitamin and mineral supplements. They also needed to provide information about their weight, height and weight change during the entire period of the COVID-19 pandemic from March 2020 until the end of November when the study was completed. For data entry and analysis, SPSS (version 25) and Microsoft Excel were used.Results: At the time of completing the survey, a slightly lower BMI of participants was noticed compared to the time before the pandemic. A statistically significant difference was determined between males and females BMI, boys BMI was slightly higher. Females gained and men lost BW. Increased intake of unhealthy types of food was associated with weight change. Increased mental stress during the pandemic was associated with dietary changes, respectively with decreased as also increased food amount. High percent of participants (40.4%) who increased their physical activity did not alter their eating in the form of the food amount. This study reported use of some dietary supplements which have not been used before the pandemic by 63.5% participants.Conclusions: This paper presents a unique insight into the changing lifestyle and eating habits of adolescents in B&H during lockdown and post-lockdown period of research. Considering that pandemic is still ongoing, data from study like this may be useful to create further steps in battling the pandemic.

Lower Adherence

A person’s chronotype determines different habits, among which are eating and physical activity. Furthermore, at the university stage, social and organisational factors have a direct effect on students’ daily attitudes and habits. Adherence to the Mediterranean diet is linked to better sleep quality and less social jet lag, but association with chronotype or sexual opinion remains unclear. The aim of this study was to assess the associations between chronotype, adherence to the Mediterranean Diet, and sexual opinion. A multicentre observational study enrolled 457 students, from the University of Castilla-La Mancha and the University of Cordoba. Sociodemographic data and adherence to the Mediterranean diet, chronotype, physical activity, and sexual opinion were collected with validated questionnaires. The study period was from December 2017 to January 2018. Our results reported that students with an evening chronotype (E-type), with evening preferences, had a lower adherence to the Mediterranean diet and showed a higher tendency towards erotophilia. E-type students reported a significantly lower intake of fruits, vegetables, pulses, cereals, and olive oil, and higher breakfast skipping. Therefore, among the measures to promote healthy habits (obesity prevention, sexual education, socialisation, etc.), chronotype and an analysis of the impact of the schedules established by the universities must be considered.

Evidence suggests that transitions among older adults towards healthy habits, such as physical activity, appear underway in developed countries such as the USA but not in developing countries such as Mexico. However, little is known about the potential benefit of physical activity in preventing disability among elders in countries at different stages of epidemiological transition. We explore the impact of physical activity on the disablement process among elders in Mexico compared to the USA. Data are from two waves of the Mexican Health and Aging Study and the Health and Retirement Study. We examine the impact of exercise on the transition from no disability to ADL limitations two years later. Findings indicate that exercise is more common in the U.S. than in Mexico. There is a positive effect of exercise on negative outcomes in both countries. However, the protective effect of exercise is stronger in the U.S. than in Mexico.

Abstract Background: This paper is based on the relationship between family structure and family health. Methods: This paper applies the method of empirical research to explore the impact of social capital investment and health behavior acquisition on the degree of completion of recommended amount of physical activity for children and adolescents under different family structures. Results: This paper finds that the 30-minute MVPA and 60-minute MVPA of children and adolescents in joint families and stem families are larger than those in other families, and the overall 60-minute MVPA participation is obviously insufficient. As for the influence of family structure and social capital on the recommended amount of physical activity for children and adolescents, compared with other families, greater expenditure on sports is related with better family-friend interaction, stronger sense of school belongingness, better campus friendship, better social trust, greater likelihood that the recommended physical activity is completed, and more social support for the physical activity of children and adolescents. Conclusions: Social capital and health behavior served as a way to improve the achievement rate of recommended physical activity for children and adolescents. But the effect of health behavior is not prominent.

Abstract Objectives The significance and objective of this study is to (1) investigate the influence current health concerns have on lifestyle choices using self-reporting assessment surveys, and (2) determine the correlation and/or impact between the stated variables on overall health status of college-age students. Methods A Health Behavior Study was conducted by the office of Healthy Campus 2020(R)(HC2020(R)), a campus-wide comprehensive wellness intervention program. IRB approved surveys were disseminated to students, (N = 59), to investigate student's health status, health behavior, possible changes in health status after one-year exposure to HC2020(R) principles, and relationships between health variables and behavior. Coded responses were obtained and analyzed. Results Descriptive analysis and correlation coefficient are used to analyze data responses. Among 14 significant ongoing health concerns listed as options, diabetes ranked highest as a health concern at 34%. Heart disease & stroke (29%), asthma and/or lung disease (24%), and both cancer and obesity at 20% followed, respectively. Consequently, 64% of students indicated they engaged in exercise or physical activity daily, emphasizing their awareness of the importance of physical activity and living a healthy lifestyle. Conclusions Results indicate health concerns among college-age students conducting self-reporting assessment surveys may influence positive lifestyle choices. Seventy-eight % (%) of students who participated in the study, ages 17–20, reported at least 4 of the same concerns of the CDC's top 10 public health problems and leading cause of death in the US. Funding Sources Funding sources for the research conducted through the office of HC2020(R) at Oakwood University was provided by The Department of Education, Title III.

Abstract Background It is estimated that less than one third of women (28%) worldwide, are not sufficiently active, and there is evidence indicating physical activity (PA) participation is lower during pregnancy and the postpartum period. Despite the importance of educating and encouraging postpartum women to engage in PA, existing systematic reviews have only focused on examining the impact of individually tailored PA interventions and on specific postpartum populations such as women who are inactive (i.e., do not meet PA recommendations) or women at risk of gestational diabetes mellitus or postnatal depression. This review aims to fill this gap by examining the impact of group-based PA interventions on postpartum women’s PA levels or other health behavior outcomes. Methods A systematic literature search was conducted using four electronic databases (MEDLINE, CINAHL, EMBASE and PsychInfo) of published studies between 1st January 2000 and 31st October 2020. Studies were included if they targeted postpartum women with no current health conditions, had children aged 0–5 years, and engaged postpartum women in a group-based PA program that reported PA or other health behavior outcomes. Out of a total of 1091 articles that were initially identified, six were included. Results Group-based PA interventions were moderately successful in changing or increasing postpartum women’s self-reported PA levels and psychological wellbeing in the first 2 years of their offspring’s life. Overall, group-based PA interventions were not successful in changing or increasing postpartum women’s objectively measured PA levels, but only one study objectively measured postpartum women’s PA levels. Narrative synthesis highlights the heterogeneity of the outcomes and methodologies used, and the low to medium risk of bias in the included studies. Conclusion To strengthen the evidence-base for group-based PA programs with postpartum women there is an on-going need for more rigorous randomised controlled trials of appropriate length (at least 3 months in duration) with an adequate dose of group-based PA sessions per week (to meet PA guidelines), and that utilise objective measures of PA. In addition, future PA interventions for this population should include, at the very least, fidelity and process data to capture the characteristics or design features that appeal most to postpartum women.

Background: Lifestyle diseases like hypertension, atherosclerosis, coronary heart disease (CAD), type –II diabetes mellitus, ischemic  stroke are  Non -communicable diseases leading to premature  sickness, disability and death. To determine the risk factors of lifestyle diseases like hypertension and diabetes mellitus and to impart health education on the risk factors of lifestyle diseases and to determine the impact of health education.Methods: A educational interventional study was conducted in a randomly selected urban slum in Peelamedu, Coimbatore funded by ICMR STS.100 Men in the age group of 30-50 years were administered questionnaire to determine the risk factors of lifestyle diseases. Health education was given to the respondents regarding risk factors. The same questionnaire was given to the respondents after the health education to determine the impact of health education. Statistical analysis was performed by using SPSS version 20. Prevalence of risk factors was presented in percentage. Paired T test was used to find out the effectiveness of Health Education.Results: Among the study population, the risk factors for life style diseases in our study are smoking (39%), alcohol intake (27%), lack of physical activity (40%), overweight (36%), obesity (14%).  The impact of health education on risk factors of lifestyle disease and it was statistically significant with smoking (p=.000), alcohol (p=.02), physical activity (p=.001) and not significant with BMI (p=.71).Conclusions: Regular health checks can be done to improve the frequency of preventive care and support for behavior change. Effective implementation of lifestyle modifications behavior like healthy diet intake, avoidance of high caloric foods, promoting physical activity help in preventing future complications as a part of   primary preventive strategies at primary care level. The importance of lifestyle modifications should be reinforced.
