Impact des facteurs nutritionnels pendant et après cancer
2021
Nutritional factors (diet, weight, alcohol, physical activity) are identified as factors having an impact on the onset of several cancer sites. Less abundant scientific data also underline their impact on the tumor progression. A review of the scientific literature was carried out by a group of experts established by the French National Cancer Institute (INCa) to better document the influence of nutritional factors during and after cancer on outcomes such as overall mortality, cancer specific mortality, recurrence, second primary cancers and quality of life. This analysis of the literature completes messages of reduction of alcohol consumption, prevention of undernutrition or excess weight …
Physical Activity and Brain Health.
2019
Physical activity (PA) has been central in the life of our species for most of its history, and thus shaped our physiology during evolution. However, only recently the health consequences of a sedentary lifestyle, and of highly energetic diets, are becoming clear. It has been also acknowledged that lifestyle and diet can induce epigenetic modifications which modify chromatin structure and gene expression, thus causing even heritable metabolic outcomes. Many studies have shown that PA can reverse at least some of the unwanted effects of sedentary lifestyle, and can also contribute in delaying brain aging and degenerative pathologies such as Alzheimer’s Disease, diabetes, and multiple s…
Physical exercise increases adult hippocampal neurogenesis in male rats provided it is aerobic and sustained
2016
Key points Aerobic exercise, such as running, enhances adult hippocampal neurogenesis (AHN) in rodents. Little is known about the effects of high-intensity interval training (HIT) or of purely anaerobic resistance training on AHN. Here, compared with a sedentary lifestyle, we report a very modest effect of HIT and no effect of resistance training on AHN in adult male rats. We found the most AHN in rats that were selectively bred for an innately high response to aerobic exercise that also run voluntarily and increase maximal running capacity. Our results confirm that sustained aerobic exercise is key in improving AHN. Abstract Aerobic exercise, such as running, has positive effects on brain …
The sensory and nutritional experience of parents guide offsprings' feeding behavior
2016
Le comportement alimentaire est régulé par des facteurs physiologiques intrinsèques et est largement influencé par l’environnement culturel. Une prise alimentaire excessive et un mode de vie trop sédentaire sont les principales raisons de l’épidémie mondiale d’obésité. Si l’influence du contexte familial sur les habitudes alimentaires ne fait aucun doute, le fait que l’état nutritionnel, métabolique et hormonal des parents avant la conception, puis de la mère pendant la gestation et l’allaitement puisse influencer le comportement alimentaire futur de l’enfant est un concept novateur qui ouvre la voie à des mesures de prévention. Au cours des dernières décennies, des travaux sur des cohortes…
Genetic and Epigenetic Modulation of Cell Functions by Physical Exercise
2019
Since ancient times, the importance of physical activity (PA) and of a wholesome diet for human health has been clearly recognized. However, only recently, it has been acknowledged that PA can reverse at least some of the unwanted effects of a sedentary lifestyle, contributing to the treatment of pathologies such as hypertension and diabetes, to the delay of aging and neurodegeneration, and even to the improvement of immunity and cognitive processes. At the same time, the cellular and molecular bases of these effects are beginning to be uncovered. The original research articles and reviews published in this Special Issue on “Genetic and Epigenetic Modulation of Cell Functions by Physical Ex…
Adolescent physical fitness and activity as predictors of adulthood activity.
2011
A 25-year population-based study was conducted to determine how physical fitness and participation in leisure-time physical activity in adolescence (age 12-18 years) predict leisure-time physical activity in adulthood (age 37-43 years). In 1976, five field tests were conducted to measure muscular fitness, agility and aerobic capacity, and self-report weekly frequencies of activity were obtained by questionnaire. A modified questionnaire was repeated in 2001, when participants were age 37-43 years (N = 1525). On the basis of the questionnaire, a physical activity index was calculated both in 1976 and 2001. The odds ratios (OR) for being inactive in adulthood among those who were physically v…
Relationship between sedentary behavior and depression: a mediation analysis of influential factors across the lifespan among 42,469 people in low- a…
2018
Abstract Background Sedentary behavior (SB) is associated with diabetes, cardiovascular disease and low mood. There is a paucity of multi-national research investigating SB and depression, particularly among low- and middle-income countries. This study investigated the association between SB and depression, and factors which influence this. Methods Cross-sectional data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health. Depression was based on the Composite International Diagnostic Interview. The association between depression and SB (self-report) was estimated by multivariable linear and logistic regression analyses. Mediation analysis was used to id…
Diet quality and lifestyle associated with free selected low-energy density diets in a representative Spanish population
2007
Objective: Dietary intake is strongly influenced by the energy density of the diet. The purpose of this study was to determine the association of energy density with diet quality, dietary reference intake (DRI) for energy and lifestyle characteristics in free-living people. Subjects: The subjects were Spanish men (n ¼ 1491) and women (n ¼ 1563) selected in between 1999 and 2000 among the general population according to the 1996 census. Results: A low-energy density diet was significantly associated (Po0.001) with a higher consumption of vegetables, fruits, legumes, fish and white meat as compared to high-energy density diets. More subjects (Po0.001) with a high adherence to low-energy densi…
The influence of parental modelling on children's physical activity and screen time: Does it differ by gender?
2016
Background: Parents play an important role in modelling healthy behaviours to their children. This study investigated associations between parent and child physical activity and screen time behaviours across specific domains, including moderating effects by parent and child gender. Method: The sample comprised 3300 school children and 2933 parents participating in the UP4FUN project (mean ages: child 11.2 ± 0.8 years, mother 40.0 ± 4.9 years, father 43.4 ± 5.8 years; 49% boys, 83% mothers). Data were collected in 2011 in Belgium, Greece, Hungary, Germany and Norway. Questionnaires assessed physical activity (sport, outdoor activities, walking and cycling for transport) and screen time (TV/D…
Rationale and methods for a randomized controlled trial of a movement-to-music video program for decreasing sedentary time among mother-child pairs
2015
Measured objectively, under a quarter of adults and fewer than half of preschool children meet the criteria set in the aerobic physical activity recommendations of the Centers for Disease Control and Prevention. Moreover, adults reportedly are sedentary (seated or lying down) for most of their waking hours. Importantly, greater amounts of sedentary time on parents’ part are associated with an increased risk of more sedentary time among their children. A randomized controlled trial targeting mother-child pairs has been designed, to examine whether a movement-to-music video program may be effective in reducing sedentary time and increasing physical activity in the home environment. Mother-chi…
