Impact of eating behavior on 24-month weight change after treatment of severe obesity-A clinical prospective cohort study.

This study aimed to evaluate the effects of self-reported baseline eating behaviors on 24-month weight change in adults with severe obesity. A prospective, nonrandomized clinical cohort study on surgical and medical obesity treatment included 971 adults (75% women) with a mean BMI of 42.0 (SD 4.9) kg/m2. To assess baseline eating behaviors and binge eating disorder, the Questionnaire on Eating and Weight Patterns-Revised and the Three-Factor Eating Questionnaire were used. In analyses adjusted for treatment, age, sex, baseline weight, and BMI, those with nocturnal eating lost less weight (3.5 kg [95% CI: 0.02-6.9]; p < 0.05) at 24 months compared to those without nocturnal eating. Binge eating disorder was not significantly associated with weight loss over 24 months. Emotional eating was associated with less weight loss at 12 months: 1.16 kg per z score (95% CI: 0.37-1.95; p < 0.05). Compared with completers, dropout from medical obesity treatment was associated with emotional and uncontrolled eating at baseline (both p < 0.001). The association between pretreatment eating behaviors and weight change was found to be generalizable and not restricted to any specific treatment. Certain eating behaviors may affect weight loss as well as attrition. Identifying eating behaviors that may impair treatment efficacy are suggested in the treatment of severe obesity.

Sleep patterns and quality among Nigerian medical students: A cross-sectional study.

Adequate sleep is crucial for individuals' well-being and cognitive functioning. However, medical students face unique challenges that disrupt their sleep patterns, such as a rigorous curriculum, long study hours, and high-stress levels. Understanding the sleep patterns and quality among medical students in Nigeria is important to develop targeted interventions and support their overall well-being. This study involved 802 medical students from 3 medical schools in Southwest Nigeria. Participants completed an online questionnaire that collected data on their demographic characteristics, sleep patterns and self-reported sleep quality. Descriptive statistics and correlation analysis were used to analyze the data and identify patterns and associations. Most participants were female (56.9%), with the highest representation from the UNILORIN (65.5%). The average reported sleep duration was 5.74 hours per night, indicating insufficient sleep. Irregular bedtimes and wake-up times were commonly reported. A significant proportion of students consumed coffee late at night (27.1%) and used medication to induce sleep (24.3%). Sleep patterns and behaviors, such as snoring (36.1%) and nocturnal eating (57.6%), were reported. Overall, participants reported satisfactory (28.3%) or poor (29.7%) sleep quality. Correlation analysis revealed significant associations between sleep patterns, sleep quality, academic performance, and other sleep-related factors. The study identified insufficient sleep duration, irregular bedtimes, late-night coffee consumption, and poor sleep quality. These findings emphasize the need for interventions and strategies to promote healthy sleep habits among medical students, which can positively impact their overall health and academic performance.

Gender differences in body composition, dietary patterns, and physical activity: insights from a cross-sectional study.

This study investigates the interplay between body composition, dietary patterns, and physical activity across genders, focusing on gender-specific differences in food preferences and eating behaviors. Understanding these interactions is crucial for developing targeted nutritional and lifestyle interventions. A cross-sectional study was conducted with 1,333 participants (58.7% female, 41.3% male), aged 18-65 years. Participants were categorized into tertiles based on their fat mass to fat-free mass (FM-to-FFM) ratio. Data on dietary choices, eating behaviors, and physical activity were collected and analyzed to identify gender-specific trends. Significant gender-specific differences were observed in food preferences and eating behaviors. Males experienced greater hunger in the late afternoon, while females felt more hunger in the morning. Males showed a preference for processed and red meats, whereas females preferred cooked vegetables. Eating behaviors such as meal skipping, uncontrolled eating, nocturnal eating, and taste preferences (sweet or salty) varied distinctly between FM-to-FFM tertiles and genders. Higher FM-to-FFM ratios correlated with lower physical activity levels, particularly in strength training and general sports engagement. These findings highlight the complex interactions between body composition, dietary habits, and lifestyle factors, emphasizing gender-specific differences. The results suggest that body composition and BMI significantly impact health-related behaviors, necessitating tailored interventions to address these differences and promote healthier lifestyles.

Reduced Interoception Abilities in Patients with Restless Legs Syndrome.

Restless legs syndrome (RLS) is a complex sensorimotor disorder occurring with a typical circadian fashion. Association with additional features, like alexithymia and nocturnal compulsive behaviors further complicates the framework. To assess interoception in RLS. A total of 25 RLS patients and 28 controls underwent the heartbeat tracking task (interoceptive accuracy [IAC]). RLS symptoms' frequency, disturbance and duration, nocturnal behaviors, interoceptive awareness (IAW), alexithymia, depressive and anxiety symptoms were also collected. RLS patients showed significant lower IAC (P = 0.0003) and IAW (P = 0.012), and reported more nocturnal eating behaviors (P < 0.001). IAC positively correlated with IAW (R = 0.32), and negatively correlated with age (R = -0.58). Nocturnal eating behavior negatively correlated with IAC (R = -0.44) and IAW (R = -0.50). RLS patients presented reduced interoceptive abilities correlating with higher nocturnal eating behaviors. Future studies are needed to explore the role of interoception in RLS pathophysiology, also in relation to other sensorimotor aspects.

Chronotype preference, sleep quality, and night-eating behaviors in patients with metabolic dysfunction-associated steatotic liver disease: Assessing the relationship with disease severity and fibrosis.

Our primary objective is to examine the variance in chronotype, night-eating patterns, and sleep quality in patients with biopsy-proven metabolic dysfunction-associated steatotic liver disease. In addition, we aim to establish a correlation between these variables and the severity of the disease and fibrosis. Patients who were following up with biopsy-proven metabolic dysfunction associated steatotic liver disease (MASLD) were included in the study. Histologically severe disease is characterized by a Steatosis, Activity, and Fibrosis activity score of ≥3 or the presence of advanced fibrosis (≥F3). Participants who met the inclusion criteria were given the Morningness and Evening Questionnaire (MEQ), the Pittsburgh Sleep Quality Index, and the Night Eating Questionnaire to complete. A total of 93 patients were included in this study. According to the MEQ, 48 patients were morning type (51.6%), and 42 (45.2%) were neither type. Sleep quality was determined to be inferior in the non-morningness group (p=0.002). A significantly higher proportion of patients with nocturnal eating syndrome had a non-morningness chronotype preference (n=22, 23.7%), compared to those with a morningness chronotype (n=9, 9.7%) (p=0.001). In the multivariate analysis, both age and poor sleep quality had significant impacts on advanced fibrosis, with odds ratios of 1.11 and 3.81, respectively. Despite the non-morningness chronotype demonstrating poorer sleep quality and a higher prevalence of night-eating behavior, our findings revealed no statistically significant differences in terms of sleep quality, nocturnal eating habits, or chronotype preferences among patients with varying degrees of MASLD severity. On the other hand, advanced fibrosis was significantly impacted by poor sleep quality.

Nocturnal Lifestyle Behaviours and Risk of Poor Sleep during Pregnancy.

The extent to which lifestyle practices at night influence sleep quality in pregnant women remains unknown. This study aimed to examine whether nocturnal behaviours were associated with poor sleep during pregnancy. We performed a cross-sectional analysis of a prospective cohort of pregnant women at 18–24 gestation weeks recruited from KK Women’s and Children’s Hospital, Singapore, between 2019 and 2021. Nocturnal behaviours were assessed with questionnaires, and sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) with a global score ≥5 indicative of poor sleep quality. Modified Poisson regression and linear regression were used to examine the association between nocturnal behaviour and sleep quality. Of 299 women, 117 (39.1%) experienced poor sleep. In the covariate-adjusted analysis, poor sleep was observed in women with nocturnal eating (risk ratio 1.51; 95% confidence interval [CI] 1.12, 2.04) and nocturnal artificial light exposure (1.63; 1.24, 2.13). Similarly, nocturnal eating (β 0.68; 95% CI 0.03, 1.32) and light exposure (1.99; 1.04, 2.94) were associated with higher PSQI score. Nocturnal physical activity and screen viewing before bedtime were not associated with sleep quality. In conclusion, reducing nocturnal eating and light exposure at night could potentially improve sleep in pregnancy.

Daytime restriction of feeding prevents illuminated night-induced impairment of metabolism and sleep in diurnal zebra finches

We investigated whether nocturnal eating was causal to the impairment of metabolism and sleep disruption in diurnal animals exposed to illuminated nights. Adult zebra finches hatched and raised in 12 h light: 12 h darkness (LD) were exposed to 5-lux dim light at night (dLAN, two groups), with a control group maintained on LD. For the next 3 weeks, the food availability to one of the dLAN groups was restricted to the 12 h light period (dLAN -F); the other dLAN (dLAN +F) and LD groups were continued on ad lib feeding. In spite of similar food intakes, dLAN +F condition led to the fat accumulation and weight gain. These birds showed concurrent changes in hepatic expression of genes associated with carbohydrate and lipid metabolism, suggesting an enhanced gluconeogenesis and impaired fatty acids synthesis. Increased sirt1 mRNA levels indicated the activation of molecular mechanisms to counter-balance the metabolic damage under dLAN +F. Furthermore, reduced bout length and total duration of the nocturnal sleep suggested a poorer sleep in dLAN +F condition. Negative sleep effects of dLAN were supported by the lower hypothalamic expression of sleep promoting sik3 and camkii genes, and higher mRNA expression of awake promoting achm3 gene in dLAN +F, compared to the LD condition. Importantly, dLAN-induced negative effects in metabolism and sleep were alleviated in the dLAN –F group. These results suggest the role of timed feeding in alleviating the negative impact of illuminated nights in metabolism and sleep in diurnal zebra finches.

Prevalence of night eating syndrome among inbound call centre employees in Kuala Lumpur, Malaysia.

Background: Night eating syndrome (NES) is described as a disordered eating pattern relative to sleep, where consumption of food occurs in the evening and night. Numerous studies had been conducted in various populations but studies on (NES) among call centre employees are limited. Aim: This study aimed to determine the prevalence of NES and its determinants among selected inbound call centre employees in Kuala Lumpur, Malaysia. Methods: In this cross-sectional study, a total of 217 inbound call centre employees were recruited through random sampling. A self-administered socio-demographic and work-related questionnaire was used to collect data on the background of the respondents. Information on NES and well-being was obtained by using the Night Eating Questionnaire (NEQ) and World Health Organisation-Five Well-Being Index (WHO-5) respectively. Data on dietary intakes, smoking habits, alcohol intakes and life stress were acquired using a Simple Lifestyle Indicator Questionnaire (SLIQ) while eating behaviour of the respondents was studied using the Three-Factor Eating Questionnaire (TFEQ-18). Results: The mean age of the respondents was 24.1 ± 6.0 years. The prevalence of NES was 12.0% (95% CI = 8.12-17.24). The binary logistic regression identified that NES is significantly associated with adequate exercise (AOR = 4.250, p = 0.012) and emotional eating (AOR = 6.510, p = 0.014). Conclusion: This study showed that the prevalence of NES was high in the call centre and repeated nocturnal eating can have multiple adverse health effects. Therefore, promoting healthy eating habits are crucial to reduce the impacts of NES.

Phentermine\u2013topiramate extended release for the dual treatment of obesity and sleep-related eating disorder: a case report

BackgroundObesity and eating disorders can present together, and pose diagnostic and therapeutic challenges to the clinician. Generally, lifestyle interventions alone for the treatment of obesity have modest long-term effectiveness. Phentermine–topiramate extended release is a relatively new medication approved for weight reduction. Sleep-related eating disorder is a rare condition that is often underdiagnosed. Both conditions are chronic and require long-term management. There is no definitive treatment for sleep-related eating disorder, and therapeutic options are based on case reports.Case presentationA 35-year-old Caucasian male with a body mass index of 41.7 kg/m2 presented for obesity treatment. History revealed nocturnal episodes of hyperphagia associated with amnesia of overeating and other features of sleep-related eating disorder. Treatment was initiated with phentermine–topiramate extended release. Five months later he lost 5% of his body weight and demonstrated resolution of sleep-related eating disorder behaviors. He reported no adverse side effects. Upon self-discontinuation of the medication, his eating disorder recurred.ConclusionsClinicians intending to help patients reduce body weight should screen for nocturnal eating and other eating disorders. Sleep-related eating disorder can be associated with significant morbidity and excess weight. Patients report adverse effects on quality of life as a result. Phentermine–topiramate extended release may be a good therapeutic option for patients presenting with comorbid obesity and sleep-related eating disorder. More research is needed to explore the efficacy and safety in this patient population.

Comorbid parasomnias in narcolepsy and idiopathic hypersomnia: more REM than NREM parasomnias.

To assess the frequency, determinants, and clinical impact of clinical rapid eye movement (REM) and non-REM (NREM) parasomnias in adult patients with narcolepsy type 1 (NT1), narcolepsy type 2 (NT2), and idiopathic hypersomnia compared with healthy controls. Familial and past and current personal parasomnias were assessed by questionnaire and medical interviews in 710 patients (220 NT1, 199 NT2, and 221 idiopathic hypersomnia) and 595 healthy controls. Except for sleep-related eating disorder, current NREM parasomnias were rare in all patient groups and controls. Sleep-related eating disorder was more frequent in NT1 patients (7.9% vs 1.8% in NT2 patients, 2.1% in patients with idiopathic hypersomnia, and 1% in controls) and associated with disrupted nighttime sleep (odds ratio = 3.9) and nocturnal eating in full awareness (odds ratio = 6.9) but not with sex. Clinical REM sleep behavior disorder was more frequent in NT1 patients (41.4%, half being violent) than in NT2 patients (13.2%) and affected men more often than women (odds ratio = 2.4). It was associated with disrupted nighttime sleep, depressive symptoms, and antidepressant use. Frequent (> 1/week) nightmares were reported by 39% of patients with NT1, 29% with NT2, and 27.8% with idiopathic hypersomnia (vs 8.3% in controls) and were associated with depressive symptoms in narcolepsy. No parasomnia (except sleep-related hallucinations) worsened daytime sleepiness. In patients with central disorders of hypersomnolence, comorbid NREM parasomnias (except for sleep-related eating disorder) are rare and do not worsen sleepiness. In contrast, REM parasomnias are prevalent (especially in NT1) and are associated with male sex, disrupted nighttime sleep, depressive symptoms, and antidepressant use.

Disrupted nighttime sleep and sleep instability in narcolepsy.

This review aimed to summarize current knowledge about disrupted nighttime sleep (DNS) and sleep instability in narcolepsy, including self-reported and objective assessments, potential causes of sleep instability, health consequences and functional burden, and management. One hundred two peer-reviewed publications from a PubMed search were included. DNS is a key symptom of narcolepsy but has received less attention than excessive daytime sleepiness and cataplexy. There has been a lack of clarity regarding the definition of DNS, as many sleep-related symptoms and conditions disrupt sleep quality in narcolepsy (eg, hallucinations, sleep paralysis, rapid eye movement sleep behavior disorder, nightmares, restless legs syndrome/periodic leg movements, nocturnal eating, sleep apnea, depression, anxiety). In addition, the intrinsic sleep instability of narcolepsy results in frequent spontaneous wakings and sleep stage transitions, contributing to DNS. Sleep instability likely emerges in the setting of orexin insufficiency/deficiency, but its exact pathophysiology remains unknown. DNS impairs quality of life among people with narcolepsy, and more research is needed to determine its contributions to cardiovascular risk. Multimodal treatment is appropriate for DNS management, including behavioral therapies, counseling on sleep hygiene, and/or medication. There is strong evidence showing improvement in self-reported sleep quality and objective sleep stability measures with sodium oxybate, but rigorous clinical trials with other pharmacotherapies are needed. Treatment may be complicated by comorbidities, concomitant medications, and mood disorders. DNS is a common symptom of narcolepsy deserving consideration in clinical care and future research.

Unhealthy Eating, Psychopathology, and Nonalcoholic Fatty Liver Disease in Youth Presenting for Bariatric Surgery.

Little is known about the behavioral and psychosocial correlates of pediatric nonalcoholic fatty liver disease (NAFLD). Given diet contributes to the development and persistence of NAFLD, we examined (1) the prevalence of unhealthy eating behaviors (UEB), (2) whether these varied by NAFLD or nonalcoholic steatohepatitis (NASH) presence, and explored (3) the association of psychopathology with NAFLD. Before metabolic and bariatric surgery (MBS), adolescents (N = 159; Mage = 16.4; MBMI = 53.7 kg/m2, 73% girls, 62.3% white) self-reported presence/absence of 10 UEB (Questionnaire on Eating and Weight Patterns-Revised, Night Eating Questionnaire, Look AHEAD). NAFLD and NASH presence was assessed by intraoperative liver biopsy. Height/weight, blood pressure, and blood specimens were obtained. A medical comorbidity index was created (prediabetes/diabetes, dyslipidemia, elevated blood pressure). Psychopathology was assessed in a subgroup completing the Youth Self-Report (N = 98). Binge eating disorder symptomatology was associated with higher odds of NAFLD whereas frequent eating out was associated with lower odds of NAFLD. Among those with NAFLD frequent eating out was associated with higher odds of NASH while nocturnal eating was associated with lower odds of NASH. Separate models identified internalizing psychopathology as associated with higher odds of NAFLD after controlling for demographics, number of UEB, and medical comorbidities. Results suggest potential phenotypical differences between adolescents presenting for MBS with/without NAFLD, with implications for behavioral/psychosocial targets for screening and intervention. Replication should occur in a sample with greater gender and ethnic diversity to improve generalizability. Understanding differences in the context of surgical weight loss and comorbidity resolution is indicated.

NonREM Disorders of Arousal and Related Parasomnias: an Updated Review.

Parasomnias are abnormal behaviors and/or experiences emanating from or associated with sleep typically manifesting as motor movements of varying semiology. We discuss mainly nonrapid eye movement sleep and related parasomnias in this article. Sleepwalking (SW), sleep terrors (ST), confusional arousals, and related disorders result from an incomplete dissociation of wakefulness from nonrapid eye movement (NREM) sleep. Conditions that provoke repeated cortical arousals, and/or promote sleep inertia, lead to NREM parasomnias by impairing normal arousal mechanisms. Changes in the cyclic alternating pattern, a biomarker of arousal instability in NREM sleep, are noted in sleepwalking disorders. Sleep-related eating disorder (SRED) is characterized by a disruption of the nocturnal fast with episodes of feeding after arousal from sleep. SRED is often associated with the use of sedative-hypnotic medications, in particular the widely prescribed benzodiazepine receptor agonists. Compelling evidence suggests that nocturnal eating may in some cases be another nonmotor manifestation of Restless Legs Syndrome (RLS). Initial management should focus upon decreasing the potential for sleep-related injury followed by treating comorbid sleep disorders and eliminating incriminating drugs. Sexsomnia is a subtype of disorders of arousal, where sexual behavior emerges from partial arousal from nonREM sleep. Overlap parasomnia disorders consist of abnormal sleep-related behavior both in nonREM and REM sleep. Status dissociatus is referred to as a breakdown of the sleep architecture where an admixture of various sleep state markers is seen without any specific demarcation. Benzodiazepine therapy can be effective in controlling SW, ST, and sexsomnia, but not SRED. Paroxetine has been reported to provide benefit in some cases of ST. Topiramate, pramipexole, and sertraline can be effective in SRED. Pharmacotherapy for other parasomnias continues to be less certain, necessitating further investigation. NREM parasomnias may resolve spontaneously but require a review of priming and predisposing factors.

Impact of Social Jetlag and Circadian Patterns on Patients with Metabolic and Nocturnal Eating Syndromes

Objective Metabolic syndrome (MS) can result in many health hazards, including coronary heart disease, diabetes, fatty liver, and several types of cancer. Social jetlag is a discrepancy between biological and social timing. Circadian rhythm disruption is suggested to disturb the hypothalamus pituitary adrenal (HPA) axis. Disturbance of the HPA axis was reported to increase the risk of developing visceral obesity and MS. We hypothesized that social and circadian rhythm disruptions negatively impact patients with obesity and MS. This study aimed to detect the associations between obesity, MS, nocturnal eating syndrome, and social jetlag. Methods One hundred obese patients were recruited (61 had MS). The patient group was compared to a healthy nonobese control group (n=50). Each studied patient was subjected to three question-naires [Morningness Eveningness Questionnaire, Night Eating Questionnaire (NEQ), and Sleep Timing Questionnaire]; their anthropometric measures were taken, fasting lipid profile, liver, and kidney function tests, and fasting insulin were also assessed. Results Patients with evening chronotype were mainly from the obese with MS group. NEQ total score was higher in obese patients with MS, and it showed a significant positive correlation with BMI. Total cholesterol, NEQ score, age, sleep latency, and awakening after sleep onset had significant associations with MS. Conclusion Evening chronotype has a significant association with MS. Social jetlag negatively impacts obesity and MS, leading patients to have frequent nocturnal eating behaviors. Screening for sleep profile and social jetlag should be included in routine clinical practice of managing obesity.

Assessment Of Pre-season Body Composition, Meal Patterns, Food Choices And Preferences In NCAA Division 1 College Athletes

The transition from high-school to college is typically associated with substantial changes in body composition, eating patterns, and food choices. PURPOSE: To assess pre-season body composition, eating patterns, food choices and preferences in Division I NCAA college athletes. METHODS: 118 incoming first-year athletes (males: n=69, BMI 25.5±5.5 kg/m2; females: n=49, BMI 22.3±2.7 kg/m2) from basketball, football, soccer, lacrosse, cross-country and tennis teams were recruited. Meal Patterns (MPQ), Food Preferences (FPQ) and Food Choices (FCQ) Questionnaires were used to assess eating patterns, factors that influence food choices and preferences. Body composition was assessed using dual energy x-ray absorptiometry (DXA) for lean body mass (LBM), fat mass (FM) and body fat % (BF%). A two-way ANOVA was used for analysis with significance accepted at p<0.05. RESULTS: Evening (86.2%) and lunch (66.1%) meals were the most frequently consumed meals followed by breakfast (52.5%) and evening snacks (21.2%). Nocturnal eating (eating during the night after having been to sleep) was the least common form of eating (31.4%). There was no significant difference observed in FPQ and FCQ between genders (p>0.05). However, a significant difference was observed in the importance of food for weight control (p=0.02), preference for vegetables (p=0.03) and starches (p=0.02) among sports. In addition, significant body composition differences were observed between males and females (FM: 13.4±10.9 kg and 17.0±7.3 kg, LBM: 67.5±9.0 kg and 44.8±5.3 kg, BF%: 14.8±8.4% and 26.7±7.3 %, p<0.001, respectively) and among sports (p<0.001 ). CONCLUSIONS: Certain eating patterns, such as skipping breakfast or lunch meals, may be detrimental to the maintenance of appropriate body composition in their sport. In addition, athletes in the endurance sports had higher preference for starches and based their food choices on the need to control weight.

Prevalence and Associated Factors of Nocturnal Eating Behavior and Sleep-Related Eating Disorder-Like Behavior in Japanese Young Adults: Results of an Internet Survey Using Munich Parasomnia Screening.

Nocturnal (night) eating syndrome and sleep-related eating disorder have common characteristics, but are considered to differ in their level of consciousness during eating behavior and recallability. To date, there have been no large population-based studies determining their similarities and differences. We conducted a cross-sectional web-based survey for Japanese young adults aged 19–25 years to identify factors associated with nocturnal eating behavior and sleep-related eating disorder-like behavior using Munich Parasomnia Screening and logistic regression. Of the 3347 participants, 160 (4.8%) reported experiencing nocturnal eating behavior and 73 (2.2%) reported experiencing sleep-related eating disorder-like behavior. Smoking (p < 0.05), use of hypnotic medications (p < 0.01), and previous and/or current sleepwalking (p < 0.001) were associated with both nocturnal eating behavior and sleep-related eating disorder-like behavior. A delayed sleep-wake schedule (p < 0.05) and sleep disturbance (p < 0.01) were associated with nocturnal eating behavior but not with sleep-related eating disorder-like behavior. Both nocturnal eating behavior and sleep-related eating disorder-like behavior had features consistent with eating disorders or parasomnias. Nocturnal eating behavior but not sleep-related eating disorder-like behavior was characterized by a sleep-awake phase delay, perhaps representing an underlying pathophysiology of nocturnal eating syndrome.

Pattern of BMI and associated factors in residents of Hussainabad aged 15 years and above.

Objectives: To study the pattern of BMI and associated factors in residents of Hussainabad aged 15 years and above. Study Design: Cross-sectional study. Setting: Hussainabad, Faisalabad. Period: 15th April to 23th August 2017. Material &amp; Methods: A sample of 410 was obtained. Participants were selected by convenience sampling. Data was collected by self-administered questionnaire. Results: Out of total 410 study participants, 250 (61%) were males and 160 (39%) were females. 258 (62.9%) participants were found having BMI in the range of overweight and obesity, 6 (1.4%) participants were underweight and the remaining 146 (36%) participants were having normal BMI range. Amongst 258 overweight/obese people, 83 (20.2%) people were overweight, 112 (27.3%) moderate obese, 30 (7.3%) severe obese and 33 (8.1%) very severe obese. Overall 175 (42.7%) people were suffering from obesity. 249 (60.7%) people were in habit of eating in between meals and 161 (39.3%) were not used to eating in between meals. 95 (23.1%) people eat four times a day and 55 (13.4%) people eat more than four times a day. Likeness and increased frequency of rice and meat [136 (33.2%) and (130 (31.7%)] was more than vegetables and pulses [(91 (22.2%) and (53 (12.9%)] respectively. 157 (38.3%) people were having nocturnal eating habits. 194 (47.3%) admitted of liking the sweets and sweet foods and 170 (41.5%) people admitted of eating more under stressful conditions. 130 (31.7%) participants don’t do any kind of physical activity. Conclusion: This study describes a high frequency of obesity among population of Hussainabad. Numerous health risk practices were identified including unhealthy dietary habits, eating sweet foods, increased meal frequency, snacking behavior and lack of physical activity.
