Increase In Mean Body Mass Index Research Articles

Mitochondrial Haplogroups and Weight Gain After Initiating ART in Patients With HIV.

We studied the association of mitochondrial DNA (mtDNA) haplogroups with weight and body mass index (BMI) gain at 96 weeks in 1019 treatment-naive persons with HIV (PWH) who initiated first-line antiretroviral therapy (ART) since 2014. The mean increase in weight and BMI over the study period was 2.90 kg and 0.98 kg/m2, respectively. We found a significant adjusted association between the major UK mtDNA haplogroup and lower weight and BMI increase at 96 weeks after ART initiation. Our findings reveal a potential role for mitochondrial genetics in the complex phenomenon of weight gain after initial ART in PWH.

Adverse drug reactions, adherence, and virologic outcomes in adult patients on dolutegravir-based antiretroviral therapy at a tertiary hospital, southeast Nigeria.

To assess the adherence, adverse drug reactions (ADR), and virologic outcomes of dolutegravir-based antiretroviral therapy. This was a retrospective chart review. A tertiary health facility-based study in Abakaliki, Nigeria. Five hundred and fifteen (515) adult patients on dolutegravir were selected using a Random Number Generator. Demographic and clinical data were extracted from patients' case notes and analysed with IBM-SPSS version-25. Adherence to dolutegravir, ADRs, virologic outcome, and change in Body Mass Index (BMI) were estimated. The mean age of the patients was 45.5±10.8 years; 68.2% of them were females; 97.1% of them had good self-reported adherence. The majority (82.9%) of them reported no ADRs and among those (17.1%) that did, headache (9.7%), body-itching (3.1%), and skin rash (2.7%) dominated. Most achieved viral suppression (94.4%) and did not have detectable viral particles (57.4%). There was a significant increase in the BMI of the patients with a mean weight increase of 0.9kg, a mean BMI increase of 0.3 kg/m2, and a 2.6% increase in the prevalence of overweight and obesity. Patients on dolutegravir reported low ADRs, good self-reported adherence, and a high viral suppression rate. However, dolutegravir is associated with weight gain. We recommend widespread use and more population-wide studies to elucidate the dolutegravir-associated weight gain. None declared.

Obesity contagion among classmates: Children's relation with each other regarding weight status, physical activity, and dietary intake

A series of influential articles suggests that obesity may spread between couples, siblings, and close friends via an obesity contagion phenomenon. Classmates, as important structural equivalents in one's social network, may experience obesity contagion. However, this has rarely been examined. Anthropometric measurements, questionnaire surveys, and geographic information were collected from 3670 children from 26 schools in Northeast China. We found that classmates were positively related in terms of body mass index (BMI), body fat, physical activity, and intake of vegetables, fruits, fast food, snacks, and sugar-sweetened beverages. One standard deviation (SD) increase in classmates' mean BMI and percentage body fat was associated with 0.19 SD higher individual BMI (95% confidence interval [CI]: 0.00, 0.39) and 0.31 SD higher percentage body fat (95% CI: 0.13, 0.48). Coefficients ranged from 0.48 to 0.76 in models for physical activity, and the dietary intake of vegetables, fruit, fast food, snacks, and sugar-sweetened beverages. Children's BMI and body fat were more strongly associated with the maximum and minimum body fat levels of their same-sex classmates than with those of their general classmates. Their dietary intake and physical activity were more strongly associated with the mean/median levels of their general classmates than with those of their same-sex classmates. This study suggests that children's BMI, body fat, physical activity, and dietary intake may be related to those of their classmates. Modeling healthy behaviors in the classroom may help children develop habits that support achieving and maintaining a healthy weight. Future interventions should consider the inclusion of classmates as a social network strategy for obesity prevention.

Effect of 18 months elexacaftor-tezacaftor-ivacaftor on body mass index and glycemic control in adults with cystic fibrosis

Malnutrition and cystic fibrosis related diabetes (CFRD) are common comorbidities in cystic fibrosis (CF). Cystic fibrosis transmembrane regulator (CFTR) modulators have shown beneficial effects on respiratory status. This study aims to determine the effect of elexacaftor-tezacaftor-ivacaftor (ETI) on body mass index (BMI) and glycemic control. A retrospective, observational study of a cohort of 17 adult CF patients was conducted at the CF reference center of Ghent University Hospital. BMI evolution was analyzed 18 months before and 0, 3, 6, 12 and 18 months after the start of ETI. The evolution of insulin dependence and the 2h oral glucose tolerance test (OGTT) results were described until 36 months after start of ETI, in a small subgroup of ten patients with CFRD or impaired glucose tolerance (IGT). A significant increase in mean BMI of 1.2kg/m2 (±1.3 SD) was observed. Most weight gain was observed in the first 3 months after starting treatment. This effect was sustained during the observed period of 18 months. Six patients had insulin dependent CFRD, of which three were able to stop insulin after starting ETI. Two patients with CFRD treated with dietary measures showed an initial normalization of the 2h OGTT, but deterioration at 36 month follow-up. After initiation of ETI an increase in BMI was observed in adults with CF. ETI can have a beneficial impact on glucose metabolism in patients with CFRD, leading to a possible need for reduction or cessation of insulin therapy.

Effect of dolutegravir-based first-line antiretroviral therapy on weight and body mass index among adult people living with HIV on follow up at health facilities in Hawassa city administration, Southern Ethiopia: a retrospective cohort study

Background The nature and burden of weight gain associated with antiretroviral treatment (ART) using a combination of Tenofovir disoproxil fumarate, lamivudine and dolutegravir (TLD) among people living with HIV (PLWH) has not been thoroughly investigated in Ethiopia. Therefore, this study aimed to evaluate changes in body weight and body mass index (BMI) in adults who initiated TLD or switched to TLD compared to those who received a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based therapies. Methods A retrospective cohort study was conducted among adult PLWH who had been receiving ART between February 2017 and October 2022 in Hawassa city administration, Sidama region. Linear mixed-effects model was used to examine BMI and body weight trends over time, while a binary logistic regression was performed to identify factors associated with a ≥ 10% weight gain. Results A total of 524 adult PLWH with a median age of 35 (interquartile range: 30–41) years were included. TLD-initiated arm experienced significantly greater mean weight (8.6 kg vs. 4.95 kg, p < 0.0001) and BMI (3.11 kg/m2 vs. 1.84 kg/m2, p < 0.0001) increase than the NNRTI-based arm at two years. However, the switched arm showed no significant difference in weight (5.6 kg) and BMI (2.13 kg/m2) compared to the NNRTI-based arm (p > 0.05). There was a significant interaction effect between ART regimens and time in predicting weight and BMI gain (p < 0.01). Initiating ART with TLD had higher odds of ≥10% body weight gain at two years (adjusted odds ratio [AOR]: 1.9; 95% CI: 1.19–3.04). Other baseline factors such as age ≥40 years (AOR: 2.02; 95% CI: 1.35–3.02), weight <50kg (AOR: 3.0; 95% CI: 1.86–4.84), advanced disease stages (AOR: 1.78; 95% CI: 1.1–2.86) and ambulatory-bedridden functional status (AOR: 2.0; 95% CI: 1.05–3.8) were also associated with ≥10% weight gain. Conclusion Initiating ART with TLD was significantly associated with greater weight and BMI gain than the NNRTI-based regimens. Therefore, the cardio-metabolic implications of weight gain after the TLD initiation in this population should be monitored and thoroughly investigated.

A retrospective study of pharmacological treatment in anorexia nervosa: 6-month and 12-month follow-up

BackgroundAnorexia nervosa (AN) is a serious and potentially life-threatening eating disorder characterized by starvation and malnutrition, a high prevalence of coexisting psychiatric conditions, marked treatment resistance, frequent medical complications, and a substantial risk of death. Body mass index (BMI) is a key measure of treatment outcome of AN and it is necessary to evaluate the long-term prognosis of AN. This study aimed to better assess the BMI course trend between different medications and timepoints in order to improve AN treatment in clinical practice.MethodsDuring the period 2010–2021, we retrospectively reviewed historical data of all patients diagnosed with AN. There were two groups in this study, which were based on the duration of follow-up. Group A was a 6-month follow-up group, comprising 93 patients (mean age 19.6 ± 6.8 years), with BMI assessed at three consecutive time points: first outpatient visit (T0), three months follow-up (T3), and six months follow-up (T6). Group B was a 12-month follow-up group comprising 36 patients (mean age 17.0 ± 5.2 years) with BMI assessed at five consecutive time points: first outpatient visit (T0), three months follow-up (T3), six months follow-up (T6), nine months follow-up (T9), and twelve months follow-up (T12). In our study, we retrospectively compared BMI courses based on patients’ usage of medication using the following variables: single medication, switching medications, combined medications, and without medications. The primary outcome measurement was BMI recorded at the 6-month follow-up and the 12-month follow-up respectively. In our study, which was conducted at Taichung Veterans General Hospital, we reviewed outpatient medical records of all patients with AN who were seen at the hospital during the period 2010–2021.ResultsIn Group A (6-month follow-up), patients treated with antidepressants showed a mean BMI increase of 1.3 (p < 0.001); patients treated with antipsychotics showed a mean BMI increase of 1.1 (p = 0.01); patients treated with switching medications showed a mean BMI increase of 0.1 (p = 0.397); patients treated with combined medications showed a mean BMI increase of 0.5 (p = 0.208); and patients treated without medications showed a mean BMI increase of 0.1 (p = 0.821). The results indicated that patients with AN had a significant BMI increase after treatment with antidepressants and antipsychotics in the 6-month follow-up group. In Group B (12-month follow-up), patients treated with antidepressants showed a mean BMI increase of 2.7 (p < 0.001); patients treated with antipsychotics showed a mean BMI increase of 2.8 (p = 0.168); patients treated with switching medications showed a mean BMI decrease of 0.8 (p = 0.595); patients treated with combined medications showed a mean BMI increase of 1.6 (p = 0.368); and patients treated without medications showed a mean BMI increase of 1.0 (p = 0.262). The results indicated that patients with AN had a significant BMI increase after treatment with antidepressants at the 12-month follow-up.ConclusionsAN is a complex disease caused by multiple factors. Evaluating its long-term prognosis is crucial. Our study provides insights and highlights three key findings: 1) medication adherence is crucial in treating AN, 2) frequent switching of medications may not promote weight gain and may also require a re-establishment of rapport with patients with AN, and 3) pharmacotherapy, especially antidepressants, is more effective than no treatment. Further research is needed to confirm these findings.

Body mass index changes in children and adolescents with intelectual disability during the COVID-19 pandemic

Introduction: Intellectual disability (ID) is a generalized neurodevelopmental disorder characterized by significantly impaired intellectual and adaptive functioning. Body mass index (BMI) is a value derived from the mass (weight) and height of a person. Due to the COVID-19 pandemic there was a lockdown of all schools and other daily sport activities. Methods: We measured the height and weight of 100 children and adolescents with intellectual disability. The measurements were taken in September 2020 and then six months later, in March 2021. The calculated BMI was transformed into age- and sex-standardized values (zBMI). Mean BMI and zBMI were compared over time and between sexes using a paired t-test and two-way mixed analysis of variance (ANOVA). The effect size was estimated using Cohen’s d. Results: On average across all groups, BMI increased by 0.5kg/m2 in the studied period. The increase in mean BMI was statistically significant for both groups of girls; the difference between girls and boys in BMI increase was marginally statistically significant. The analysis of zBMI confirmed that the observed changes were likely not simply a consequence of maturation. Discussion: One effect of the COVID-19 pandemic and restrictions related to it was the increase of BMI values in children and youth. With our results, we can relate this data also to population with ID. Although we have provided intervention programs and encouraged pupils and their parents to be more physically active during lockdown, the importance of school and after school activities regarding physical fitness status is clearly evident.

Differences in body mass index trajectories of adolescent psychiatric inpatients by sex, age, diagnosis and medication: an exploratory longitudinal, mixed effects analysis.

Adolescents in secure psychiatric care typically report high obesity rates. However, longitudinal research exploring the rate and extent of change is sparse. This study aimed to analyse sex differences in longitudinal body mass index (BMI) change for adolescents receiving treatment in a secure psychiatric hospital. The sample comprised 670 adolescents in secure psychiatric care. BMI trajectories from admission to 50 months of hospitalisation were produced using sex-stratified multilevel models. Systematic difference in mean BMI trajectories according to age at admission (14, 15, 16, or 17 years), medication (Olanzapine or Sodium Valproate), and primary diagnosis (Psychotic, non-Psychotic or Functional/behavioural disorders) were investigated. Together, males and females experienced a mean BMI increase of 2.22 m/kg2 over the 50-month period. For females, BMI increased from 25.69 m/kg2 to 30.31 m/kg2 , and for males, reduced from 25.01 m/kg2 to 23.95 m/kg2 . From 30 to 50 months, a plateau was observed for females and a reduction in BMI observed for males. Psychotic disorders in males (β 3.87; CI 1.1-6.7) were associated with the greatest rate of BMI change. For medication, Olanzapine in females was associated with the greatest rate of change (β1.78; CI -.89-4.47). This is the first longitudinal study exploring longitudinal BMI change for adolescent inpatients. Results highlight that individual differences in adolescent inpatients result in differing levels of risk to weight gain in secure care. Specifically, males with psychotic disorders and females taking Olanzapine present the greatest risk of weight gain. This has implications for the prioritisation of interventions for those most at risk of weight gain.

Trends and Disparities in Adult Body Mass Index Across the 47 Prefectures of Japan, 1975-2018: A Bayesian Spatiotemporal Analysis of National Household Surveys.

BackgroundAmong high-income countries, Japan has a low prevalence of obesity, but little is understood about subnational trends and variations in body mass index (BMI), largely owing to the lack of data from representative samples of prefectures. We aimed to examine long-term trends and distributions of adult BMI at the prefecture level in Japan from the late 1970s using a spatiotemporal model.MethodsWe obtained cross-sectional data for 233,988 men and 261,086 women aged 20–79 years from the 44 annual National Health and Nutrition Surveys (NHNS) conducted during 1975–2018. We applied a Bayesian spatiotemporal model to estimate the annual time series of age-standardized and age-specific mean BMI by 20-year age group and sex for each of the 47 prefectures. We assessed socioeconomic inequalities in BMI across prefectures using the concentration index, according to population density.ResultsIn men, the age-standardized prefectural mean BMI ranged from 21.7 kg/m2 (95% credible interval, 21.6–21.9) to 23.1 kg/m2 (22.9–23.4) in 1975 and from 23.5 kg/m2 (23.3–23.7) to 24.8 kg/m2 (24.6–25.1) in 2018. In women, the age-standardized prefectural mean BMI ranged from 22.0 kg/m2 (21.9–22.2) to 23.4 kg/m2 (23.2–23.6) in 1975 and from 21.7 kg/m2 (21.6–22.0) to 23.5 kg/m2 (23.2–23.8) in 2018. Mean BMI was highest in the southernmost prefecture for most of the study period, followed by northeast prefectures. The increase in mean BMI was largest in southwest prefectures, which caught up with northeast prefectures over time. The concentration index was negative, indicating higher BMI in less-populated prefectures. Absolute values of the concentration index were greater in women than in men and increased over time.ConclusionsThere were variations in adult mean BMI across prefectures, and geographic distributions changed over time. Further national and local efforts are needed to address the rising trend in mean BMI, particularly among men in rural prefectures, and socioeconomic inequalities among women. Bayesian hierarchical modeling is useful for reconstructing long-term spatiotemporal trends of mean BMI by integrating small-sized survey samples at the prefecture level in the NHNS.

Artificial Urinary Sphincter Reverses Weight Gain Associated with Post-Prostatectomy Incontinence

ABSTRACT Introduction Post-prostatectomy stress urinary incontinence (PPI) is associated with decreased physical activity, a known risk factor for weight gain and negative health outcomes. The relationships of PPI severity and its surgical correction to body mass index (BMI) are unknown. Objective We sought to examine the association between urinary incontinence severity and BMI changes before and after artificial urinary sphincter (AUS) insertion. Methods We performed a single-institution, retrospective review of 1513 AUS and inflatable penile prosthesis (IPP) insertion cases performed between 2008 and 2020. Inclusion criteria included a history of radical prostatectomy (RP) and complete data on PPI and BMI. The IPP cohort served as a surgical control. PPI severity was assessed by pads per day (PPD). BMI data were reviewed at the following three time points: (a) at RP, (b) at urologic prosthetic surgery (UPS), and (c) 12 months post-UPS. Multivariable linear regression assessed the associations between (a) PPI severity and BMI change from RP to UPS and (b) AUS insertion and BMI change 12 months post-UPS. Results We identified 250 men (187 AUS and 63 IPP) who met selection criteria. Men in the AUS group had a mean BMI increase between RP and UPS of + 1.0 kg/m2 versus - 0.6 kg/m2 in the IPP group (p &amp;lt; 0.01, duration 26.0 ± 21.8 months). Higher PPD use was associated with greater BMI gain after RP (Figure 1A, p = 0.03). On multivariable analysis, higher PPD use at the time of UPS was positively associated with BMI gain (Rho coeff. 0.50 kg/m2, p &amp;lt; 0.01), independent of RT and ADT. AUS insertion was independently associated with a decrease in BMI of -2.83 kg/m2 12 months post-UPS (p = 0.02) on multivariable analysis. Magnitude of incontinence improvement after AUS insertion was associated with greater BMI reduction at 12 months (Figure 1B, p = 0.04). Conclusions PPI is associated with weight gain, and its correction via AUS insertion is associated with weight loss. Because severe PPI is a potential risk factor for weight gain and subsequent negative health outcomes, timely anti-incontinence surgery is prudent for prostate cancer survivorship care.

Changes in children’s physical fitness, BMI and health-related quality of life after the first 2020 COVID-19 lockdown in England: A longitudinal study

ABSTRACT We aimed to assess one-year changes in physical fitness, health-related quality of life (HRQoL) and body mass index (BMI), encompassing the 2020 COVID-19 UK lockdowns. Data were collected (October 2019, November 2020) from 178 8–10–year-olds in Newcastle-upon-Tyne, England, 85% from England’s most deprived quintile. Twenty-metre shuttle run test performance (20mSRT), handgrip strength (HGS), standing broad jump (SBJ), sit-and-reach, height, body mass, HRQoL (Kidscreen-27 questionnaire) and sports club participation were measured. BMI z-scores and overweight/obesity were calculated (≥85th centile). Paired t-tests and linear regression assessed change, adjusting for baseline BMI. Significant (p<0.001) changes were observed: increases in mean BMI (+1.5kg·m−2), overweight/obesity (33% to 47%), SBJ (+6.8cm) and HGS (+1.5kg); decreases in 20mSRT performance (−3 shuttles), sit-and-reach (−1.8cm). More children at follow-up were categorized “very low” for 20mSRT performance (35% baseline v 51%). Increased BMI z-score was associated with decreased “Physical Wellbeing” HRQoL. Follow-up sports club participation was associated with better 20mSRT performance (p=0.032), and “Autonomy & Parents” (p=0.011), “Social Support & Peers” (p=0.038) HRQoL. Children’s 20mSRT performance and BMI changed adversely over one year; national lockdowns potentially made negative contributions. Physical fitness, physical activity and sports programmes should be part of children’s physical and mental recovery from the pandemic.

Effect of Sodium Valproate on Weight, Body Mass Index, Uric Acid, Vitamin D3, Blood Insulin, and Serum Lipid Profile in Children

Introduction: Due to the high prevalence of epilepsy and the use of sodium valproate as an antiepileptic drug by these patients, accurate recognition of its side effects and its effects on serum lipids profile, liver enzymes, uric acid level, and thyroid function tests, especially in cases that need long-term treatment seems essential. This study aimed to evaluate the effects of sodium valproate on weight, body mass index (BMI), vitamin D3, blood insulin, uric acid level, and serum lipids profile in children with newly diagnosed epilepsy. Materials and Methods: This prospective study was performed on 30 children between 3 and 8 years of age who suffered from newly diagnosed epilepsy and received sodium valproate as monotherapy. Data including demographic information (age, sex, height, weight, and waist and hip circumference of children), as well as clinical characteristics, such as liver enzymes (ALT, AST, ALK-P), serum lipids level (TG, TC, HDL-C, LDL-C), thyroid tests (TSH, T4), fasting blood sugar (FBS), uric acid level, 25 OH Vitamin D3 (Vit-D3), and blood insulin level of children before and six months after the consumption of sodium valproate, were examined. Results: The mean weight of children before and six months after the start of sodium valproate treatment was 18.54±2.99 and 21.13±3.93 (kg), respectively. This difference was statistically significant (P=0.005). Also, the mean weight Z-score of children before and after taking sodium valproate was -2.497 and -2.293, respectively, which was statistically significant too. In addition to weight gain, there was also a significant increase in the abdominal and hip circumference of children after taking valproate, whereas the increase in mean BMI before and after valproate administration was not statistically significant (P=0.114). However, mean weight gain, as well as the increase in the waist and hip circumference, had no relationship with gender (P&gt; 0.05). Also, sodium valproate significantly increased the ALT level (P=0.046). Moreover, sodium valproate did not affect other liver function markers (AST), thyroid hormones (TSH, T4), fasting blood sugar (FBS), uric acid level, 25 OH Vit-D3, and the children's blood insulin levels (P&gt; 0.05). Conclusion: According to the findings of this study, it can be concluded that sodium valproate is a good drug for children between 3 and 8 years of age, but it should be noted that taking this drug increases the chance of obesity in children. The main side effect of this drug is weight gain. Due to the significant increase in ALT enzyme, as observed in this study, it is recommended to check liver enzymes before, one, and six months after starting treatment as it can prevent the irreversible permanent side effects of this drug.

Recent trends in adult body mass index and prevalence of excess weight: Data from the Canadian Primary Care Sentinel Surveillance Network.

To explore recent body mass index (BMI) trends over time among Canadian adults seen in primary care to identify the best target groups for preventive interventions. Retrospective descriptive cohort design. Data for this study were derived from the Canadian Primary Care Sentinel Surveillance Network database. All patients aged 18 years and older who had BMI measurements available between 2011 and 2016 were identified. A closed cohort (N = 243 078 unique patients) with a start date of January 1, 2011, was defined. Patients were excluded if key variables were missing or if BMI measurements were 15 kg/m2 or less or 50 kg/m2 or greater. The dependent variable for this study was BMI (kg/m2). Measured BMI values recorded in electronic medical records were used. A linear mixed-effect estimate was fit to model changes in BMI over time with control of baseline age and sex. Patients in the Canadian Primary Care Sentinel Surveillance Network database experienced a modest increase in mean (95% CI) BMI by 2.1% from 28.5 (28.4 to 28.6) kg/m2 in 2011 to 29.1 (28.9 to 29.2) kg/m2 in 2016 (P < .0001). This increase is not a measured difference in BMI in the same individual but reflects the difference in the average BMI of the population in 2011 versus 2016. Male patients had BMI values that were on average 1.02 kg/m2 higher than those of female patients (P < .0001). Mean BMI values increased most rapidly in young adults (18 to 34 years) compared with older adults. The findings indicate that current obesity management in primary care is failing to moderate weight trajectories in different groups by age and sex. The results also suggest that younger age groups, in whom accelerated weight gain occurred, should be the target of prevention initiatives.

Acceleration in BMI gain following COVID-19 restrictions. A longitudinal study with 7- to 10-year-old primary school children.

SummaryBackgroundThe ramifications of COVID‐19 restrictions might accelerate the already rising proportion of children with overweight or obesity.ObjectivesTo assess the association between COVID‐19 restrictions and changes in body mass index (BMI) and the proportion of children with overweight or obesity.MethodsCohort study with baseline measurements in September 2019 (prior to COVID‐19 restrictions) and follow‐up in June 2020, September 2020, and March 2021 at 12 primary schools in Austria. The height and weight of 738 children aged 7 to 10 years were measured and age‐ and sex‐specific national and international standardized values were calculated. Changes over time were analysed by analysis of variance.ResultsMean BMIIOTF standard deviation scores (SDS) increased by 0.24 (95% CI, 0.21–0.28) between September 2019 and March 2021. The proportion of children with overweight or obesity increased from 20.7% to 26.2% during this period (p < 0.001) using national reference values—EQUI BMIAUT—comparable results were observed. Simultaneously, the heightAUT SDS increased by 0.06 (95% CI, 0.05–0.08) with a larger increase in girls (+0.11; p < 0.001) than in boys (+0.03; p = 0.19).ConclusionsCOVID‐19 restrictions were associated with accelerated increases in mean BMI and the proportion of children with overweight or obesity. The increase in height SDS in girls calls for further investigations.

Alterações no índice de massa corporal: Coorte em indivíduos em uso de dolutegravir

Goal: To assess body mass index (BMI) changes in people living with HIV (PLHIV) and using antiretroviral therapy (ART) with dolutegravir (DTG) and its associated factors. Methods: Retrospective and prospective cohorts of PLHIV who started ART with DTG or used DTG after changing the therapeutic regimen, from Belo Horizonte, between February/2017 and March/2020. Data were gathered from clinical records of the Drug Logistics and Laboratory Test Control Systems. BMI changes were analyzed in the following week intervals 1-24(t24), 25-48(t48), 49-72(t73), and 73-96(t96) using the Wilcoxon test and generalized estimation equation (GEE) model, at 5% significance level. Results: A total of 614 individuals were included and average was 38.4 years old. Most were men (85.5%) and 52.3% had started ART with DTG. These individuals, and the immunosuppressed ones, showed significant increases in BMI when compared to those who used DTG after switching therapeutics or the non-immunosuppressed ones (p-value &lt;0.05). After 96 weeks, individuals starting ART with DTG had a mean increase in BMI of 1.02 Kg/m2, whereas those who used DTG after the therapeutic change had an increase of 0.56 Kg/m2 (p&lt;0.05). DTG use length, ART type, immune status, baseline BMI, and age were associated (p&lt;0.05) with BMI increases. Conclusions: We observed an increase in BMI both in individuals starting ART with DTG use and those using it after changing the therapeutic regimen.

Is vitamin D status associated with non-communicable disease risk in children? A cohort study

Background: Studies in children and adults have reported variations in 25-hydroxyvitamin D (25(OH)D), body mass index (BMI) and blood pressure (BP) over time. Furthermore, there has been a reported association of 25(OH)D with BMI, BP and lipid levels in some cross-sectional and longitudinal studies. Methods: This is a longitudinal study of a group of adolescents with measurements of 25(OH)D, BP, anthropometry and lipids at the ages of 11, 12 13, 15 and 18–20 years. For age-related changes, year 12 participants (n = 261) were matched with year 18–20 participants (n = 368), resulting in 200 paired participants. Longitudinal analyses using the Generalized Estimating Equations (GEE) comprised the following groups of participants, Year 11 (n = 288), Year 12 (n = 253), Year 13 (n = 292), Year 15 (n = 238) and Year 18–20 (n = 368). The relationship of 25(OH)D with BMI, BP and lipid levels over a period of 10 years was assessed. Results: There were significant increases in mean BMI and BP, and decreases in 25(OH)D levels with age (all p-values < 0.0001). In females, systolic BP was significantly higher in older participants (18–20) years than younger participants (12 years), but 25(OH)D was significantly higher in younger than older participants. In males, there was significant increase in BP in participants between age 12 years and 18–20 years. 25(OH)D, total cholesterol (TC) and low-density lipoprotein (LDL-C) were significantly lower in 18–20-year-old participants compared with 12-year-old participants. Longitudinally, 25(OH)D was inversely associated with LDL-C. Conclusion: There is evidence of changes in 25(OH)D, BMI and BP in adolescents over a period of 10 years. After adjusting for covariates, BMI and LDL-C were significantly negatively associated with 25(OH)D, which suggests that vitamin D status might be associated positively with favourable lipid profiles in children and adolescents.

The relationships of PPI severity and its surgical correction to body mass index (BMI) are unknown. We examined the association between urinary incontinence severity and BMI changes before and after artificial urinary sphincter (AUS) insertion. METHODS: We performed a single-institution, retrospective review of 1513 AUS and inflatable penile prosthesis (IPP) insertion cases performed between 2008 and 2020. Inclusion criteria included a history of radical prostatectomy (RP) and complete data on PPI and BMI. The IPP cohort served as a surgical control. PPI severity was assessed by pads per day (PPD). BMI data were reviewed at the following three time points: (a) at RP, (b) at urologic prosthetic surgery (UPS), and (c) 12 months post-UPS. Multivariable linear regression assessed the associations between (a) PPI severity and BMI change from RP to UPS and (b) AUS insertion and BMI change 12 months post-UPS. RESULTS: We identified 250 men (187 AUS and 63 IPP) who met selection criteria. Men in the AUS group had a mean BMI increase between RP and UPS of +1.0 kg/m2 versus - 0.6 kg/m2 in the IPP group (p<0.01, duration 26.0 +21.8 months). Higher PPD use was associated with greater BMI gain after RP (Figure 1A, p=0.03). On multivariable analysis, higher PPD use at the time of UPS was positively associated with BMI gain (Rho coeff. 0.50 kg/m2, p<0.01), independent of RT and ADT. AUS insertion was independently associated with a decrease in BMI of -2.83 kg/m2 12 months post-UPS (p=0.02) on multivariable analysis. Magnitude of incontinence improvement after AUS insertion was associated with greater BMI reduction at 12 months (Figure 1B, p=0.04). CONCLUSIONS: PPI is associated with weight gain, and its correction via AUS insertion is associated with weight loss. Because severe PPI is a potential risk factor for weight gain and subsequent negative health outcomes, timely anti-incontinence surgery is prudent for prostate cancer survivorship care.

1019Socioeconomic inequities in 5-year weight trajectories in association with baseline weight-related perceptions: a longitudinal study

Abstract Background Recognition of overweight may be a necessary pre-cursor for weight-reduction, but some suggest under-perceiving overweight may be protective against obesity. Differential responses may occur across socioeconomic strata. Methods Five-year body mass index (BMI) trajectories were examined using multilevel models of 8174 participants stratified by gender, neighbourhood socioeconomic circumstances, baseline BMI and perceived weight status, adjusting for potential confounders. Results At baseline, weight-related dissatisfaction and perceived overweight were associated with higher mean BMI, regardless of whether people were classified as ‘normal’ or overweight by WHO criteria. Mean BMI did not decrease among people classified as overweight who perceived themselves as overweight, or expressed weight-related dissatisfaction. Among those with ‘normal’ BMI at baseline but dissatisfied with their weight, mean BMI increased disproportionately among people in disadvantaged areas. Mean BMI also rose disproportionately for people in disadvantaged areas among those feeling overweight, despite having a ‘normal’ BMI, compared to people with the same over-perception but living in affluent areas. Conclusions No evidence was found to suggest accurate recognition of overweight or expressing weight-related dissatisfaction leads to a lower BMI. However, there was evidence of an increase in mean BMI among people who felt dissatisfied with, or over-perceived their ‘normal’ weight, especially in socioeconomically disadvantaged areas. Key messages Correction of under-perceptions may not drive weight loss, but circumstances contributing to over-perception and dissatisfaction with weight status may contribute to increased weight gain and exacerbate socioeconomic inequities in BMI.

Restoration of Continence after Prostatectomy is Associated With Weight Loss: A Pilot Study

To examine association between post-prostatectomy incontinence (PPI) severity and weight changes before and after restoration of continence via artificial urinary sphincter (AUS). Single surgeon, retrospective review of urologic prosthetic surgery (UPS) after radical prostatectomy (RP). A cohort of post-RP inflatable penile prosthesis (IPP) patients served as a surgical control. Body Mass Index (BMI) and total body weight were assessed pre and post-UPS. Multivariable linear regression was utilized to assess BMI changes post-UPS. 187 AUS and 63 IPP patients met selection criteria. Greater PPI severity was associated with faster BMI gain after RP (coeff. 0.14 kg/m2, P=0.03, per pad used) and magnitude of incontinence improvement (mean reduction in daily pad use) after AUS insertion was associated with greater BMI reduction at 12 months post-UPS (coeff. - 0.13kg/m2, P=0.04). On multivariable regression, AUS insertion was associated with a decrease in BMI by - 2.83 kg/m2 12 months post-UPS (P=0.02). Twelve months post-UPS, men with AUS exhibited a mean BMI reduction of -1.0 kg/m2 compared to a mean BMI increase in the IPP cohort of 0.4kg/m2 (P < 0.01). Compared to IPP, AUS patients experienced absolute body weight reduction by 6 kg [Median(IQR): 90.4 (80.3-100.1) vs 96.4 (87.1-108.8) kg, P=0.03], with nearly one-third having clinically significant weight loss (>5% body weight) at 12 months post-UPS (31.8% vs 8.3%, P < 0.01). Severe PPI appears to be associated with weight gain and correction of PPI via AUS insertion with weight loss.

Life-course trajectories of body mass index from adolescence to old age: Racial and educational disparities

No research exists on how body mass index (BMI) changes with age over the full life span and social disparities therein. This study aims to fill the gap using an innovative life-course research design and analytic methods to model BMI trajectories from early adolescence to old age across 20th-century birth cohorts and test sociodemographic variation in such trajectories. We conducted the pooled integrative data analysis (IDA) to combine data from four national population-based NIH longitudinal cohort studies that collectively cover multiple stages of the life course (Add Health, MIDUS, ACL, and HRS) and estimate mixed-effects models of age trajectories of BMI for men and women. We examined associations of BMI trajectories with birth cohort, race/ethnicity, parental education, and adult educational attainment. We found higher mean levels of and larger increases in BMI with age across more recent birth cohorts as compared with earlier-born cohorts. Black and Hispanic excesses in BMI compared with Whites were present early in life and persisted at all ages, and, in the case of Black-White disparities, were of larger magnitude for more recent cohorts. Higher parental and adulthood educational attainment were associated with lower levels of BMI at all ages. Women with college-educated parents also experienced less cohort increase in mean BMI. Both race and education disparities in BMI trajectories were larger for women compared with men.
