Abstract Individuals tend to report more stressors on days after nights with fewer hours of sleep. There may be individual differences such that this negative sleep duration—stressor perception relationship is stronger for some than others, which may have implications for health outcomes. However, we know little about whether differences in stressor perception in response to insufficient sleep (“psychocognitive reactivity to insufficient sleep”) are associated with health outcomes such as body weight. This study examined whether psychocognitive reactivity to insufficient sleep were associated with body mass index (BMI) in midlife workers. We used a sample of 127 office workers (Mage=45.2±6.2) who participated in a daily diary study for 8 consecutive days as part of the Work, Family, and Health Study. Multilevel models tested whether daily number of stressors was predicted by previous nights’ sleep. We outputted within-person slopes of stressors regressed on sleep duration to predict BMI (kg/m2). Analyses adjusted for sociodemographic characteristics and mean stressors across days. On average, workers reported more stressors following nights with shorter sleep duration than usual (negative slope means higher reactivity). Compared to those with average reactivity (within ±½SD; reference), workers with higher reactivity (≤-½SD) had higher BMI (p<.05). The BMI of these workers fell in the obese range. This study is one of the first to report that middle-aged workers with higher psychocognitive reactivity to insufficient sleep may be at greater risk for obesity. Future interventions should focus on improving middle-aged workers’ sleep health to reduce next-day stressors and thereby improve their body weight.

Bmi Trajectory

ObjectivesTo investigate whether body mass index (BMI) trajectory, lifestyle and reproductive factors are associated with knee pain risk among middle-aged women.DesignProspective study of the Japan Nurses’ Health Study (JNHS).SettingThe JNHS investigates the health of female nurses in Japan. Biennial follow-up questionnaires are mailed to the participants.ParticipantsThe 7434 women aged over 40 years who responded to the 10-year self-administered follow-up questionnaire.Primary outcome measureSelf-reported knee pain at the 10-year follow-up was the primary outcome. We analysed BMI (normal or overweight) trajectory data from a baseline survey to the 10-year follow-up survey using group-based trajectory modelling. Exposure measurements were BMI trajectory, BMI at age 18 years, lifestyle variables and reproductive history.ResultsBMI trajectories from baseline to the 10-year follow-up were divided into four groups: remained normal, remained overweight, gained weight or lost weight. At the 10-year follow-up, 1281 women (17.2%) reported knee pain. Multivariable logistic regression analysis revealed that compared with the remained normal group, multivariable-adjusted ORs (95% CI) of knee pain were 1.93 (1.60 to 2.33) for the remained overweight group, 1.60 (1.23 to 2.08) for the gained weight group and 1.40 (0.88 to 2.21) for the lost weight group. The attributable risk percent (95% CI) of the remained overweight group was 48.1% (37.3% to 57.0%) compared with the reference group of remained normal. Alcohol intake at baseline was significantly associated with knee pain.ConclusionsThe lost weight group had a lower risk than the remained overweight group and the gained weight group and did not carry statistically significant risks for knee pain. Weight reduction and maintaining a normal BMI in middle age was important for preventing knee pain in women.

Ample Evidence

There is ample evidence from animal and human observations that extremes of body weight influence reproductive processes. Women who are under a certain weight or body mass index are less likely to cycle regularly, have more difficulty in getting pregnant and have smaller babies. Those who are overweight also suffer serious reproductive problems in that they have a greater risk of oligo- or amenorrhoea, infertility and gestational diabetes. Several large epidemiological studies indicate that reproduction is adversely affected by excess weight. Two of the largest studies (Nurses' Health Study and the British Birth Cohort Study) that convincingly show that being overweight impairs menstrual and fertility function indicate that the greater the body weight and body mass index (BMI), the more significant the effect. Being overweight in adolescence appears to affect reproductive function later in life.

Walking Exercise

Background and Study Aim. The objective of this study is to examine the effect of exercise on the blood levels of homocysteine, hemoglobin and hematocrit in middle-aged sedentary individuals. Material and Methods. A total of 24 middle-aged (35-55 years) sedentary individuals (12 females and 12 males) living in Batman province voluntarily participated in this study. Body weight, body mass index, Homocysteine, Hemoglobin and Hematocrit  blood levels were measured before and after a walking exercise scheduled for 6 weeks. Walking exercise was administered 4 days a week for the 6 weeks. Initially, the walking exercises started as 40 min and increased to 60 min towards the end of the program. In the exercises, walking tempo was kept higher than normal and in parallel to the overall health levels of the subjects. The data obtained were then analyzed through the SPSS 25.00 package program. Results. It was determined that there were statistically significant differences in the pretest and posttest parameters of body weight, body mass index, and Homocysteine  values. Additionally, it was determined that, after the 6-week exercise program applied to the female and male participants, there were statistically significant differences between the pretest and posttest parameters of body weight, body mass index, hematocrit, hemoglobin, and homocysteine blood levels. Conclusions. As the conclusion, it was determined that, after the 6-week exercise program applied to a total of 24 participants (12 females and 12 males), there were statistically significant changes in the values of body weight, body mass index, hematocrit, hemoglobin, and homocysteine blood levels. It is suggested for further studies to apply nutrition programs and exercise protocols on young people regularly doing exercise and active athletes in different branches in order to contribute to sports science.

Abstract Objective To assess the association between intake of non-sugar sweeteners (NSS) and important health outcomes in generally healthy or overweight/obese adults and children. Design Systematic review following standard Cochrane review methodology. Data sources Medline (Ovid), Embase, Cochrane CENTRAL, WHO International Clinical Trials Registry Platform, Clinicaltrials.gov, and reference lists of relevant publications. Eligibility criteria for selecting studies Studies including generally healthy adults or children with or without overweight or obesity were eligible. Included study designs allowed for a direct comparison of no intake or lower intake of NSS with higher NSS intake. NSSs had to be clearly named, the dose had to be within the acceptable daily intake, and the intervention duration had to be at least seven days. Main outcome measures Body weight or body mass index, glycaemic control, oral health, eating behaviour, preference for sweet taste, cancer, cardiovascular disease, kidney disease, mood, behaviour, neurocognition, and adverse effects. Results The search resulted in 13 941 unique records. Of 56 individual studies that provided data for this review, 35 were observational studies. In adults, evidence of very low and low certainty from a limited number of small studies indicated a small beneficial effect of NSSs on body mass index (mean difference −0.6, 95% confidence interval −1.19 to −0.01; two studies, n=174) and fasting blood glucose (−0.16 mmol/L, −0.26 to −0.06; two, n=52). Lower doses of NSSs were associated with lower weight gain (−0.09 kg, −0.13 to −0.05; one, n=17 934) compared with higher doses of NSSs (very low certainty of evidence). For all other outcomes, no differences were detected between the use and non-use of NSSs, or between different doses of NSSs. No evidence of any effect of NSSs was seen on overweight or obese adults or children actively trying to lose weight (very low to moderate certainty). In children, a smaller increase in body mass index z score was observed with NSS intake compared with sugar intake (−0.15, −0.17 to −0.12; two, n=528, moderate certainty of evidence), but no significant differences were observed in body weight (−0.60 kg, −1.33 to 0.14; two, n=467, low certainty of evidence), or between different doses of NSSs (very low to moderate certainty). Conclusions Most health outcomes did not seem to have differences between the NSS exposed and unexposed groups. Of the few studies identified for each outcome, most had few participants, were of short duration, and their methodological and reporting quality was limited; therefore, confidence in the reported results is limited. Future studies should assess the effects of NSSs with an appropriate intervention duration. Detailed descriptions of interventions, comparators, and outcomes should be included in all reports.

AbstractObjectivesThe combination of sleep duration, television (TV) time and body mass index (BMI) may be related to the alteration of cardiometabolic risk. However, there are few studies that use these variables grouped, and showing the moderating role of age. This study aimed to verify if the combination of sleep duration, TV time and BMI is associated with cardiometabolic risk and the moderating role of age in this relationship in youth.MethodsCross-sectional study conducted with 1411 adolescents (611 male), aged 10–17 years. Sleep duration, TV time and BMI were assessed and grouped into eight categories. Cardiometabolic risk was assessed by a continuous metabolic risk score, including the following variables: low HDL-cholesterol, elevated triglycerides, dysglycemia, high systolic blood pressure, high waist circumference and low cardiorespiratory fitness. Generalized linear models were used to test moderation of age in the relationship between the eight categories of sleep duration/television time/BMI with cardiometabolic risk.ResultsCardiometabolic risk factor showed association with all overweight or obesity independent of sleep time and TV time. Age moderated the relationship between sleep duration/television time/BMI with cardiometabolic risk. This association was stronger in younger adolescents (11 and 13 years), indicating that individuals with inadequate sleep, prolonged TV time and overweight/obesity present higher cardiometabolic risk values when compared to 15-year-old adolescents.ConclusionOverweight/obesity, independently of sleep duration and TV time, is the main risk factor for cardiometabolic disorders in adolescence. When moderated by age, younger adolescents that presented the combination of risk factors had higher cardiometabolic risk.
