Validation of a food frequency questionnaire for use in Italian adults living in Sicily.

2015

The objective of this study was to validate two interviewer-led food frequency questionnaires (FFQs) of very different lengths: a medium-length FFQ (medium-FFQ) of 36 items and a short-length FFQ (short-FFQ) of 18 items, intending to measure levels of intakes in a local population. Both FFQs were validated against intakes derived from a 3-day dietary record (3-day DR). Sixty-five non-diabetic adults with no known cardiovascular, renal or other systemic diseases were included. High correlation coefficients between the FFQ and the 3-day DR (0.45-0.73) were observed for energy intake, carbohydrates and lipid and protein intake. Bland-Altman plots showed good agreement between the methods. Low …

Untersuchungen über die chronische Toxizität der Ascorbinsäure bei der Ratte

1963

Bei einer chronischen Verabreichung (10 Wochen) von 6,5 g Ascorbinsaure je kg Korpergewicht per os wurden bei der Ratte keine schadlichen Wirkungen beobachtet, selbst wenn die Tiere einer Stressituation (4 Wochen dauernde eiweisarme Ernahrung) unterworfen wurden. Tagesdosen von 27,3 g/kg Korpergewicht erwiesen sich als sicher toxisch. Die Mortalitatsrate betrug bei dieser Dosierung 77% innerhalb von 4 Wochen. Auf Grund dieser Versuche kann man als oberste Grenze der Vertraglichkeit bei chronischer Zufuhr 10 g Ascorbinsaure je kg Korpergewicht annehmen. Unter Zugrundelegung dieser Zahl ergibt sich fur die als wunschenswert erachtete Tagesdosis von 75 mg fur den Menschen eine Sicherheitsspann…

Low Protein Intake Is Associated with a Major Reduction in IGF-1, Cancer, and Overall Mortality in the 65 and Younger but Not Older Population

2014

SummaryMice and humans with growth hormone receptor/IGF-1 deficiencies display major reductions in age-related diseases. Because protein restriction reduces GHR-IGF-1 activity, we examined links between protein intake and mortality. Respondents aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a 4-fold increase in cancer death risk during the following 18 years. These associations were either abolished or attenuated if the proteins were plant derived. Conversely, high protein intake was associated with reduced cancer and overall mortality in respondents over 65, but a 5-fold increase in diabetes mortality across all ages. Mouse studies confirmed the effect…

Association between IGF-1 levels ranges and all-cause mortality: A meta-analysis

2022

The association between IGF-1 levels and mortality in humans is complex with low levels being associated with both low and high mortality. The present meta-analysis investigates this complex relationship between IGF-1 and all-cause mortality in prospective cohort studies. A systematic literature search was conducted in PubMed/MEDLINE, Scopus, and Cochrane Library up to September 2019. Published studies were eligible for the meta-analysis if they had a prospective cohort design, a hazard ratio (HR) and 95% confidence interval (CI) for two or more categories of IGF-1 and were conducted among adults. A random-effects model with a restricted maximum likelihood heterogeneity variance estimator w…

Masteroppgave idrettsvitenskap ME517 - Universitetet i Agder 2019 Background: Muscle strengthand poweris a determining feature of performance in many different sports and thephysiologicalfactors that affect muscle functionare many. Previous studies have mostly concernedadult athletes, while researchfeaturing young elite athletes or differences between sports have been scarce. Purpose: The study’s purposeis to investigate possibleconnectionsbetween physiological factors such as resting metabolic rate, protein intake, and fat-free mass and muscle functionamong young elite athletes in southern Norway.Differences between sport-groupswere alsoinvestigated. Method: A total of 36young elite athlet…

Dietary Microperiodization in Elite Female and Male Runners and Race Walkers During a Block of High Intensity Precompetition Training.

2017

We investigated one week of dietary microperiodization in elite female (n = 23) and male (n = 15) runners and race-walkers by examining the frequency of training sessions and recovery periods conducted with recommended carbohydrate (CHO) and protein availability. Food and training diaries were recorded in relation to HARD (intense or >90min sessions; KEY) versus RECOVERY days (other-than KEY sessions; EASY). The targets for amount and timing of CHO and protein around KEY sessions were based on current nutrition recommendations. Relative daily energy and CHO intake was significantly (p < .05) higher in males (224 ± 26 kJ/kg/d, 7.3 ± 1.4 g/kg/d CHO) than females (204 ± 29 kJ/kg/d, 6.2 ±…

Zur Frage der Schutzwirkung von Thiamin bei chronischer Alkoholintoxikation

1960

Ratten wurden nach Entwohnung in 3 Gruppen zu je 42–50 Tieren auf folgende Weise ernahrt: a) die Kontrolltiere erhielten eine leberschadigende Kost und Trinkwasser, b) die Tiere der Gruppe I leberschadigende Kost und 16%igen Alkohol, dazu von der 5. Versuchswoche an 40 γ Thiamin pro Tier und Tag, d. i. die zehnfache Normaldosis, c) diejenigen der Gruppe II leberschadigende Diat und Alkohol.

Actigraphic Sleep and Dietary Macronutrient Intake in Children Aged 6–9 Years Old: A Pilot Study

2019

The objective of this study was to examine the relationship between different sleep parameters and energy and macronutrient intake in school-aged children. A total of 203 children 6 to 9 years of age participated in this cross-sectional study. Anthropometric measurements were taken first. Diet was assessed with 3-day food logs and sleep was measured with a questionnaire on sleep quality and a wrist actigraph worn for at least 7 days. A decrease of 165.45 kcal was observed per each additional hour of sleep during the week (β (95% CI) = −165.45 (−274.01, −56.88)
