His Internal medicine study frequently links to other fields, such as Diabetes mellitus.
His Obesity study combines topics in areas such as Aerobic exercise and Disease.
The Body mass index study combines topics in areas such as Cross-sectional study, Lean body mass, Anthropometry and Demography.
His Cross-sectional study research includes elements of Screen time and Environmental health.
His most cited work include:
- Systematic review of the health benefits of physical activity and fitness in school-aged children and youth (2492 citations)
- Low relative skeletal muscle mass (sarcopenia) in older persons is associated with functional impairment and physical disability. (2083 citations)
- Skeletal muscle mass and distribution in 468 men and women aged 18–88 yr (1602 citations)
What are the main themes of his work throughout his whole career to date?
His primary areas of investigation include Gerontology, Demography, Obesity, Internal medicine and Body mass index.
His Gerontology research is multidisciplinary, relying on both Physical fitness, Epidemiology, Public health, Health indicator and Screen time.
His Demography research is multidisciplinary, incorporating elements of Logistic regression and Quartile, Confidence interval.
His work carried out in the field of Obesity brings together such families of science as Cohort and Environmental health.
Ian Janssen has included themes like Diabetes mellitus, Endocrinology and Cardiology in his Internal medicine study.
His study in Body mass index is interdisciplinary in nature, drawing from both Physical therapy and National Health and Nutrition Examination Survey.
He most often published in these fields:
- Gerontology (25.37%)
- Demography (22.83%)
- Obesity (24.10%)
What were the highlights of his more recent work (between 2017-2021)?
- Demography (22.83%)
- Gerontology (25.37%)
- Screen time (9.30%)
In recent papers he was focusing on the following fields of study:
Ian Janssen spends much of his time researching Demography, Gerontology, Screen time, Internal medicine and Menopause.
His biological study spans a wide range of topics, including Sleep duration, Sleep in non-human animals, Body mass index and Diabetes mellitus.
His studies examine the connections between Body mass index and genetics, as well as such issues in Confidence interval, with regards to Obesity.
His work in Gerontology tackles topics such as Systematic review which are related to areas like Novelty.
His Screen time study integrates concerns from other disciplines, such as Psychological intervention, Cross-sectional study, Odds, Substance use and Mental health.
The concepts of his Internal medicine study are interwoven with issues in Endocrinology and Cardiology.
Between 2017 and 2021, his most popular works were:
- Obesity in adults: a clinical practice guideline (38 citations)
- Canadian 24-Hour Movement Guidelines for Adults aged 18-64 years and Adults aged 65 years or older: an integration of physical activity, sedentary behaviour, and sleep. (27 citations)
- Compositional associations of time spent in sleep, sedentary behavior and physical activity with obesity measures in children. (26 citations)
In his most recent research, the most cited papers focused on:
- Internal medicine
- Cancer
- Diabetes mellitus
Ian Janssen focuses on Gerontology, Demography, Screen time, Public health and Sleep in non-human animals.
His Gerontology research integrates issues from Cognitive skill, Cognition and Systematic review.
In his study, Internal medicine is strongly linked to Longitudinal study, which falls under the umbrella field of Cognition.
His studies in Demography integrate themes in fields like Cross-sectional study, Accelerometer data and Epidemiology.
Ian Janssen has included themes like Sedentary behavior, Negatively associated, Waist and Repeated measures design in his Sleep in non-human animals study.
His Guideline research focuses on Obesity and how it relates to Physical fitness.
