Project description:BackgroundYounger people are more likely to report cybercrime than older people. As older people spend more time online, this may change. If similarly exposed, risk factors including social isolation and poor health could make older adults disproportionally susceptible. We aimed to explore whether cybercrime risks and their predictors vary between age groups.MethodsWe analysed responses from 35,069 participants aged 16+ in the 2019/20 Crime Survey for England and Wales (CSEW). We investigated, among people who have used the internet in the past year, risks of experiencing any cybercrime, repeat victimisation and associated financial loss across age groups.ResultsDespite being at lower risk of reporting any cybercrime in the past year, people aged 75+ were more likely to report financial loss resulting from cybercrime victimisation (OR 4.25, p = 0.037) and repeat cybercrime victimisation (OR 2.03, p = 0.074) than younger people. Men, those from Mixed or Black ethnic groups, more deprived areas, managerial professional groups, and with worse health were at greater cybercrime risk.DiscussionWhile younger adults are more at risk from cybercrime, older adults disclosed more severe cases (repetitive victimisation and associated financial loss), perhaps due to lesser awareness of scams and reporting options. As most people experience declining health as they age, greater understanding of why poor health predicts cybercrime could inform prevention initiatives that would particularly benefit older age groups and mitigate risks of growing internet use among older adults. Health and social care professionals may be well positioned to support prevention.

Project description:ObjectiveTo examine whether the adverse effect of obesity on psychological well-being can be explained by weight discrimination.MethodsThe study sample included 5056 older (≥50 y) men and women living in England and participating in the English Longitudinal Study of Ageing. Participants reported experiences of weight discrimination in everyday life and completed measures of quality of life (CASP-19 scale), life satisfaction (Satisfaction With Life Scale), and depressive symptoms (eight-item CES-D scale). Height and weight were objectively measured, with obesity defined as BMI ≥30 kg/m2 . Mediation analyses were used to test the role of perceived weight discrimination in the relationship between obesity and each psychological factor.ResultsObesity, weight discrimination, and psychological well-being were all significantly inter-related. Mediation models revealed significant indirect effects of obesity through perceived weight discrimination on quality of life (β = -0.072, SE = 0.008), life satisfaction (β = -0.038, SE = 0.008), and depressive symptoms (β = 0.057, SE = 0.008), with perceived weight discrimination explaining approximately 40% (range: 39.5-44.1%) of the total association between obesity and psychological well-being.ConclusionsPerceived weight discrimination explains a substantial proportion of the association between obesity and psychological well-being in English older adults. Efforts to reduce weight stigma in society could help to reduce the psychological burden of obesity.

Project description:CagriSema is a combination of amylin (cagrilintide) and glucagon-like peptide-1 (semaglutide) analogues being developed for weight management. We quantified CagriSema’s action on energy intake and expenditure in rats. CagriSema caused 12% weight loss and a 39% reduction in food intake. In contrast, pair-feeding caused less weight loss while weight-matching required a 51% decrease in food intake. Approximately 1/3 of CagriSema’s weight loss efficacy was from an energy expenditure effect, blunting of metabolic adaptation, which is likely a hallmark of successful treatment of obesity.

Project description:BackgroundThe body mass index (BMI) is closely related to mortality risk, and energy intake (EI) is essential for maintaining energy balance in weight control. However, self-reported EI has been shown to lead to a systematic underestimation. Total energy expenditure measured using the doubly labelled water (DLW) method is considered an objective biomarker of EI and the gold standard for its estimation in individuals with stable body weight. We aimed to examine the association between DLW-calibrated EI and BMI on overall mortality risk in older adults.MethodsA prospective cohort study was performed using data of 8051 (4267 women and 3784 men) Japanese older adults from the Kyoto-Kameoka Study in Japan. Calibrated EI was calculated from the estimated EI using a food frequency questionnaire and equation developed based on DLW. Participants were classified by quartiles based on their EI stratified by sex. BMI was calculated using self-reported height and body weight. Mortality data were collected between 30 July 2011 and 30 November 2016. Statistical analysis was performed using the multivariable-adjusted Cox proportional hazard model with a restricted cubic spline.ResultsThe 8051 participants' mean (standard deviation) age and BMI were 73.5 (6.1) years and 22.6 (3.0) kg/m2 , respectively. The mean (standard deviation) EI with and without calibration was 1909 (145) kcal/day and 1569 (358) kcal/day in women and 2383 (160) kcal/day and 1980 (515) kcal/day in men, respectively. During the median 4.75 years of follow-up (36 552 person-years), 661 deaths were recorded. In both women (hazard ratio [HR], 0.63; 95% confidence interval [CI] [0.41, 0.98]) and men (HR, 0.62; 95% CI [0.44, 0.87]), after adjusting for confounders, the top quartile as compared with the bottom calibrated EI quartile showed a negative association with risk of all-cause mortality. The lowest HR for all-cause mortality was 1900-2000 kcal/day in women and 2400-2600 kcal/day in men. However, after adjusting for BMI, no significant association was observed between the calibrated EI and the risk of death. These associations could not be confirmed in the uncalibrated EI. The HR for mortality was minimal at a BMI of 23 kg/m2 in both men and women, with or without adjustment for the calibrated EI.ConclusionsCalibrated EI was negatively associated with mortality risk but not uncalibrated EI. This may be mediated by an increase in body weight over time. Caution is required when interpreting the association between EI and mortality risk without adjusting for self-reported measurement errors and outcomes.

Project description:IntroductionThis study investigated older adults' emotional and social experiences of physical activity and exercise during the first Covid-19 lockdown in England.MethodsParticipants were 24 older adults (M = 74 years, SD = 5.0) either physically active or inactive before lockdown. Semi-structured interviews were conducted at the start of the pandemic in England, and when restrictions were lifted eight weeks later.ResultsTemplate analysis revealed three main themes: a Sense of Purpose for Being Physically Active, Routes for Engagement, and Inactive by Force? with different sub-themes for active and inactive participants. The lockdown restrictions emphasised the need to keep physically active in both active and inactive participants, but they perceived barriers differently. Both active and inactive participants found a renewed sense of purpose in walking outdoors for exercise when restrictions eased, enhancing their physical and mental well-being.DiscussionTo reduce barriers and emphasise that exercise is for all ages and all levels of mobility, multi-modal recommendations are presented for educating, promoting, supporting, and enabling older adults to engage in physical activity and exercise.

Project description:ObjectiveTo estimate the daily dietary energy intake for me to maintain a constant body weight. How hard can it be?DesignVery introspective study.SettingAt home. In lockdown. (Except every Tuesday afternoon and Saturday morning, when I went for a run.) PARTICIPANTS: Me. n=1.Main outcome measuresMy weight, measured each day.ResultsSleeping, I shed about a kilogram each night (1.07 (SD 0.25) kg). Running 5 km, I shed about half a kilogram (0.57 (SD 0.15) kg). My daily equilibrium energy intake is about 10 000 kJ (10 286 (SD 201) kJ). Every kJ above (or below) 10 000 kJ adds (or subtracts) about 40 mg (35.4 (SD 3.2) mg).ConclusionsBody weight data show persistent variability, even when the screws of control are tightened and tightened.

Project description:PurposeThe objective of this investigation is to study how excess body weight influences the energy cost of walking (Cw) and determine whether overweight and obese older adults self-select stride frequency to minimize Cw.MethodsUsing body mass index (BMI), men and women between the ages of 65 and 80 yr were separated into normal weight (NW, BMI ≤24.9 kg·m(-2), n = 13) and overweight-obese groups (OWOB, BMI ≥25.0 kg·m(-2), n = 13). Subjects walked at 0.83 m·s on an instrumented treadmill that recorded gait parameters and completed three 6-min walking trials; at a preferred stride frequency (PSF), at +10% PSF, and at -10% PSF. Cw was determined by indirect calorimetry. Repeated-measures ANOVA was used to compare groups, and associations were tested with Pearson correlations, α = 0.05.ResultsOWOB had 62% greater absolute Cw (301 ± 108 vs 186 ± 104 J·m, P < 0.001) and 20% greater relative Cw(kg) (3.48 ± 0.95 vs 2.91 ± 0.94 J·kg(-1)·m(-1), P = 0.046) than NW. Although PSF was not different between OWOB and NW (P = 0.626), Cw was 8% greater in OWOB at +10% PSF (P < 0.001). At PSF, OWOB spent less time in single-limb support (33.1% ± 1.5% vs. 34.9% ± 1.6 % gait cycle, P = 0.021) and more time in double-limb support (17.5% ± 1.6% vs 15.4% ± 1.4% gait cycle, P = 0.026) than NW. In OWOB, at PSF, Cw was correlated to impulse (r = -0.57, P = 0.027) and stride frequency (r = 0.51, P = 0.046).ConclusionsExcess body weight is associated with greater Cw in older adults, possibly contributing to reduced mobility in overweight and obese older persons.

Project description:This research aimed to replicate a previous UK-based finding that low craving control predicts increased intake of high energy density foods (HED) during the COVID-19 lockdown, and extend this finding to adults living in Victoria, Australia. The study also assessed whether acceptance coping moderates the relationship between craving control and increased HED food intake, and examined the associations between trait disinhibition, perceived stress and changes to HED food intake. An online survey completed by 124 adults living in Victoria, Australia (total eligible n = 147; 38.5 ± 12.9 years) during the COVID-19 lockdown showed that 49% of participants reported increased overall food intake, and 21-29% reported increased intake of HED sweet and savoury foods during the COVID-19 lockdown. Of the eating behaviour traits assessed, low craving control was the only significant predictor of increased HED sweet and savoury food intake (cognitive restraint, disinhibition and emotional eating were non-significant predictors). Perceived stress was associated with reported increases in overall savoury and sweet snack intake, but was not significantly associated with changes to specific HED food groups (sweet and savoury). In this sample, acceptance coping did not significantly moderate the relationship between craving control and increased HED food intake. Based on these replicated findings, further trials should now consider interventions targeting craving control to promote controlled food intake in individuals at-risk of weight gain during the current COVID-19 and future potential lockdowns.

Project description:BackgroundIndividuals with overweight or obesity commonly underreport energy intake (EI), but it is unknown if the tendency to underreport persists in formerly obese individuals who lose significant weight and maintain their weight loss over long periods of time.ObjectiveAssess the accuracy of self-reported EI in successful weight loss maintainers (WLM) compared with controls of normal body weight (NC) and controls with overweight/obesity (OC).MethodsParticipants for this case-controlled study were recruited in 3 groups: WLM [n = 26, BMI (in kg/m2) 24.1 ± 2.3; maintaining ≥13.6 kg weight loss for ≥1 y], NC (n = 33, BMI 22.7 ± 1.9; similar to current BMI of WLM), and OC (n = 32, BMI 34.0 ± 4.6; similar to pre-weight loss BMI of WLM). Total daily energy expenditure (TDEE) was measured over 7 d using the doubly labeled water (DLW) method, and self-reported EI was concurrently measured from 3-d diet diaries. DLW TDEE and self-reported EI were compared to determine accuracy of self-reported EI.ResultsWLM underreported EI (median, interquartile range) (-605, -915 to -314 kcal/d) to a greater degree than NC (-308, -471 to -68 kcal/d; P < 0.01) but not more than OC (-310, -970 to 18 kcal/d; P = 0.21). WLM also showed a greater degree of relative underreporting (-25.3%, -32.9% to -12.5%) compared with NC (-14.3%, -19.6% to -3.1%; P = 0.02) but not OC (-11.2%, -34.1% to -0.7%; P = 0.16). A greater proportion of WLM was classified as underreporters (30.8%) than NC (9.1%; P = 0.05) but not OC (28.1%; P = 1.00).ConclusionsWLM underreported EI in both absolute and relative terms to a greater extent than NC but not OC. These findings call into question the accuracy of self-reported EI in WLM published in previous studies and align with recent data suggesting that WLM rely less on chronic EI restriction and more on high levels of physical activity to maintain weight loss. This trial was registered at clinicaltrials.gov as NCT03422380.

Project description:ObjectivesThe present study evaluated the association between energy intake, energy required and mortality in older adults.DesignA cohort study with a mean of 10·67 (sd 4·74) years of follow-up. Participants completed a 24 h dietary recall. Energy required per day was computed by BMR. Deaths through 2006 were identified from the National Death Index. A Cox regression was used to estimate the hazard ratios (HR) of quantiles of energy intake and energy required on all-cause and CVD mortality, adjusting for demographics, socio-economic status and co-morbidity.SettingThe National Health and Nutrition Examination Survey (NHANES) III, 1988-1994.SubjectsA total of 4846 participants aged 60 years or above were analysed.ResultsWithin the follow-up period, there were a total of 2954 deaths (61·0 %), 51·9 % were caused by CVD. Relative to those in quartile 1 of energy intake, only quartile 4 was associated with all-cause mortality and CVD mortality with HR of 0·86 (95 % CI 0·77, 0·96, P=0·006) and 0·76 (95 % CI 0·65, 0·89, P=0·001), respectively. On the other hand, relative to those in quartile 1 of energy required, all quartiles of participants had a lower risk of all-cause mortality and CVD mortality. The interaction effects between energy intake and energy required with all-cause and CVD mortality were insignificant (P=0·70 and 0·61, respectively).ConclusionsIndependent of energy required, higher energy intake was associated with lower HR of both all-cause and CVD mortality in older adults.
