“…Third, the amount and quality of physical activity were only assessed using self‐administered questionnaires, not with more specific tools, because this study was analyzed based on a health screening examination. However, numerous studies on exercise or physical activity were conducted, which used self‐administered questionnaires to assess the amount and quality of exercise . Therefore, this might not be the limitations.…”

The presence of abdominal obesity and lack of physical activity are both risk factors for the development of hypertension. The aim of this study was to analyze the risk of developing hypertension according to baseline waist circumference (WC). In total, 16 312 476 non‐hypertensive participants who were covered by the National Health Insurance Service (NHIS) from 2009 to 2012 in Korea were included in the study. The participants were divided into six groups according to the level of baseline WC with a 5‐cm interval starting from 80 cm in men and 75 cm in women. The risk for the future development of hypertension was assessed in 2015 using the claims data on the diagnosis of hypertension and prescription of anti‐hypertensive medications. Approximately 7.8% of the participants developed hypertension over a median follow‐up of 5.48 years. The proportion of participants who developed hypertension significantly increased from 4.2% in the WC level 1% to 17.5% in the WC level 6. After adjusting for confounding factors, level 6 of the baseline WC had a higher hazard ratio (HR) for the development of hypertension among the 6 levels of baseline with level 3 as the reference (1736; 95% confidence interval [95% CI]: 1.72‐1.753). The participants with abdominal obesity had a significantly higher HR than those without abdominal obesity regardless of whether they engage in high‐ or moderate‐intensity physical intensity (1.741; 95% CI: 1.718‐1.764). WC had a linear association with the development of hypertension based on this large nationwide population‐based cohort study, which was not influenced by physical activity.

“…In examining key variables used in ST analyses, a number of studies reported that poor sleep [ 68 , 72 , 87 , 169 ], reduced physical activity [ 90 , 118 , 174 , 203 ], and less in-person social interactions [ 67 , 72 , 197 ] were potential mediators between ST and a range of psychological outcomes. Furthermore, a number of studies reported that associations were found to differ by child sex [ 80 , 88 , 99 , 106 , 115 , 117 , 119 , 128 , 130 , 134 , 141 , 143 , 155 – 157 , 164 , 170 , 174 , 177 , 183 , 190 , 196 , 205 , 214 , 220 , 224 , 225 ] and age [ 85 , 93 , 115 , 186 , 215 , 223 ]. As summarised in Fig 4 , age and sex potentially confound associations as they independently affect both ST and psychological well-being, while the lifestyle variables are thought to be pathways through which elevated ST operates to impact on psychological well-being.…”

Psychological impacts of “screen time” and “green time” for children and adolescents: A systematic scoping review

et al. 2020

Technological developments in recent decades have increased young people's engagement with screen-based technologies (screen time), and a reduction in young people's contact with nature (green time) has been observed concurrently. This combination of high screen time and low green time may affect mental health and well-being. The aim of this systematic scoping review was to collate evidence assessing associations between screen time, green time, and psychological outcomes (including mental health, cognitive functioning, and academic achievement) for young children (<5 years), schoolchildren (5-11 years), early adolescents (12-14 years), and older adolescents (15-18 years). Original quantitative studies were identified in four databases (PubMed, PsycInfo, Scopus, Embase), resulting in 186 eligible studies. A third of included studies were undertaken in Europe and almost as many in the United States. The majority of studies were cross-sectional (62%). In general, high levels of screen time appeared to be associated with unfavourable psychological outcomes while green time appeared to be associated with favourable psychological outcomes. The ways screen time and green time were conceptualised and measured were highly heterogeneous, limiting the ability to synthesise the literature. The preponderance of cross-sectional studies with broadly similar findings, despite heterogeneous exposure measures, suggested results were not artefacts. However, additional high-quality longitudinal studies and randomised controlled trials are needed to make a compelling case for causal relationships. Different developmental stages appeared to shape which exposures and outcomes were salient. Young people from low socioeconomic backgrounds may be disproportionately affected by high screen time and low green time. Future research should distinguish between passive and interactive screen activities, and incidental versus purposive exposure to nature. Few studies considered screen time and green time together, and possible reciprocal psychological effects. However, there is preliminary evidence that green time could buffer consequences of high screen time, therefore nature may be an under-utilised public health resource for youth psychological well-being in a high-tech era.

“…An online, cross-sectional survey in the UK showed that University policy to improve students' diets should incorporate efforts to promote student engagement in cooking and food preparation, and increased availability of low cost healthier food items [13]. Promotion of an active lifestyle in childhood may prevent both internalizing and externalizing disorders during adolescence [19] and could improve the mental health and well-being of students [20].…”

“…Overeating is often used as a means of coping with stress [5], and a reduced number of meals is usually caused by constant haste and a lack of properly shaped nutrition patterns, which are normally determined by social and psychological factors (level of education, level of knowledge), demographics such as social origin, family size, place of residence, economic status (family income) or lifestyle, cultural practices and individual preferences [13,18]. Low physical activity, sedentary behaviours and poor diet quality can lead to poor mental health [19,20]. Many young people who begin university study change their living environment and have to become self-reliant.…”

Introduction: Human nutrition depends on many factors. Cultural practices, socio-psychological and economic factors play important roles in development of correct nutrition patterns. Eating habits are formed most strongly during childhood and adolescence. When young people begin university study, their way of life changes significantly. In this study group, not only do the necessities of independent living and food preparation occur, but also a change the country of residence. The aim of the study was to investigate the dietary habits of medical students of the English programme. Materials and methods: The material consisted of data collected from an anonymous survey distributed among 1st year students of the Faculty of Medicine and Dentistry (28 men and 52 women). The study used a questionnaire consisting of open and multi-choice questions concerning the anthropometric data of subjects and principles of nutrition. Data were analysed statistically. Results:Obesity was generally not observed in the group of examined students. In most cases body mass index (BMI) remained in the normal range. Cases of obesity were observed only among the men. There were no significant differences between the men and women in terms of the regularity of meals. About 50% of the study population declared a regular consumption of 3 main meals a day. Significantly more women than men followed slimming diets. We did not observe significant differences between men and women in terms of activities concerned with controlling weight. Significantly more women than men had fruits and vegetables every day. Men more often consumed sweets, coffee and fast-food. Analysis of the results showed abnormal patterns in the quality and quantity of meals. Conclusions: It is essential to introduce measures in the field of nutrition education into the curriculum in order to shape appropriate patterns of healthy nutrition among future doctors and thus prevent lifestyle diseases caused by inappropriate dietary habits.
