The present study investigated trends in reported energy intake, macronutrient intake, physical activity level (PAL) and body weight and effects of excluding under-reporters (UR). Dietary intake and time spent in sixteen activity categories were recorded by 887 female university students (median age 29 years) from 1988 to 2003. Energy expenditure (EE) and PAL were measured using a factorial method. All data collected were self-reported. Individuals with reported EI:EE<0·76 were classified as UR. The remainder were classified as non-under-reporters (NUR). Trends were determined from simple linear regression of median data for each year for the entire cohort (ALL) and for NUR and UR separately, and from multiple regression analysis with the subgroups (NUR and UR) as an additional predictor (BOTH). Prevalence of under-reporting and overweight increased between 1988 and 2003. In ALL and BOTH there were trends to increased body mass, protein intake (g/d and % energy) and carbohydrate intake (% energy only) and decreased fat and alcohol intakes (g/d and % energy). In BOTH there were also increases in reported EI and carbohydrate intake (g/d). None of the trends in NUR was significantly different from those in UR, but some trends in ALL and/or BOTH were not significant when UR were excluded. Trends remaining significant in NUR were increased reported energy intake, protein (g/d) and carbohydrate (g/d) intakes, and decreased fat (% energy only) intake. There were no significant trends in PAL. We conclude that some, but not all, dietary trends were affected by exclusion of UR.

Dietary Record

Alcohol forms a significant component of many diets and it supplements rather than displaces daily energy intake. Surprisingly, alcohol intake does not systematically increase body weight. The present study assessed whether a higher level of habitual physical activity in the daily environment is associated with a higher alcohol intake. Alcohol intake as part of total food intake was measured with a 7 d dietary record while at the same time physical activity was monitored with a tri-axial accelerometer for movement registration. Subjects were twenty women and twenty-four men, aged 61±5 years, of BMI 27·1±4·6 kg/m2. Between subjects, there was a positive association between the level of habitual physical activity and alcohol intake (r 0·41; P<0·01). The subjects with higher alcohol intake had a higher activity level. On days with and days without alcohol consumption there was no difference in physical activity within subjects. In conclusion, it was shown that subjects with higher alcohol consumption are habitually more active. This may explain the lack of increasing body weight through additional energy intake from alcohol.

Abstract Introduction Obesity is a major health problem. Many treatments have been designed to help overweight/obese people to lose weight, but their effectiveness is highly variable. The same treatments may work for some persons while others have no responses — weight loss resistance. We tested whether the daily rhythm of cardiac autonomic control contributes to weight loss resistance. Methods We studied 39 overweight/obese Caucasian women (BMI&gt;25; age: 21–62 years old) who completed (1) an obesity dietary treatment of up to 30 weeks with weekly assessments of body weight, and (2) ambulatory monitoring of electrocardiogram (ECG) for up to 3.5 days. Heartbeat intervals were derived from ECG. Cardiac autonomic control was assessed in each 1-h bin by examining the temporal correlation in heartbeat fluctuations — a nonlinear measure that quantifies the delicate dynamic interplay between sympathetic and vagal outflows. Daily rhythm was estimated using the cosinor analysis. Results Weight loss was highly variable (range: 0.68%-21.78 % of initial body weight). The correlation in heartbeat fluctuations displayed a 24-h rhythm (p&lt;0.0001) with fewer correlations (more random) during the nighttime. The phase (peak timing) of the rhythm was highly variable, i.e., 10AM to 8PM for most participants, and after midnight in four participants. Weight loss evolution depended on the phase (p=0.006) in a nonlinear manner. Specifically, participants with the phase between 2PM-8PM lost weight faster than those with phases before 2PM and those after 8PM. The effect was independent of total energy intake, physical activity level, and sleep/wake schedules. Conclusion Cardiac autonomic control in overweight/obese women displayed a daily rhythm. The timing of the rhythm had previously un-identified contributions to weight loss. The inter-individual differences in the timing may reflect different circadian regulation of autonomic function and its interaction with the daily behavioral cycle.

Adult Cats

The prevalence of feline obesity is influenced by numerous factors, including inactivity and overconsumption of food. The objective of the present study was to evaluate the effect of feeding frequency on physical activity in adult cats. A total of twelve healthy adult cats were used in a cross-over study consisting of 32 d. In each of the two periods, six cats were fed either two meals or four meals daily. Throughout the study, cats were fed the same diet at amounts to maintain body weight and body condition score. Cats were individually housed 4 h/d at each scheduled feeding time, while for the other 20 h, cats were group-housed to allow for voluntary physical activity in the room with a 16 h light–8 h dark cycle. Voluntary activity levels were evaluated using Actical activity collars for seven consecutive days in each period. Daily average activity level for two-meal-fed cats (20·04 (sem 2·19), activity counts/epoch (15 s)) was not different from four-meal-fed cats (20·14 (sem 2·15), activity counts/epoch (15 s); P>0·05). In conclusion, when group-housed cats are fed to maintain their body weight and body condition score, varied feeding frequency between twice and four times daily may not affect activity levels.

Abstract The β3-adrenergic receptor (ADRB3) is expressed mainly in visceral adipose tissue and is thought to contribute to lipolysis and the delivery of free fatty acids to the portal vein. Although many studies have examined the relationship between the Trp64Arg mutation of ADRB3 and obesity, the results have been inconsistent. We examined the cross-sectional relationship of ADRB3 variants with indexes of obesity, and their longitudinal changes over 10 yr, in men and women, aged 40–69 yr, who were randomly selected from the Japanese rural population. The study considered both dietary energy intake and physical activity levels. Among the 746 participants, the genotype frequencies of the Trp64Trp, Trp64Arg, and Arg64Arg variants were 483, 224, and 39, respectively. The cross-sectional analysis showed no significant differences in height, weight, body mass index, blood pressure, serum total and high density lipoprotein cholesterols, and hemoglobin A1c among the genotype groups even after adjustments for gender, age, smoking, alcohol drinking, physical activity, and energy intake. No significant differences in the weight changes between the genotype groups were evident in the longitudinal analysis. We conclude that the Trp64Arg mutation of ADRB3 has little or no influence on either body weight or body mass index in the general Japanese population.

Una de las causas atribuibles a la reducción de los niveles de práctica de actividad física en jóvenes es el aumento del uso de los videojuegos. El objetivo de este estudio fue conocer el nivel de práctica de actividad física y su relación con el uso de videojuegos y el rendimiento académico en estudiantes universitarios. Ochenta y siete estudiantes (edad = 20 ± 6 años, 42 hombres y 45 mujeres) pertenecientes al Grado en Ciencias de la Actividad Física y del Deporte y al Grado de Educación Primaria participaron en el estudio. La recogida de datos serealizó medianteloscuestionariosPhysician-based Assessment and Counseling for Exercise yel Cuestionariode Experiencia Relacionada conlos Videojuegos. El rendimiento académico se analizó mediante la nota media de los estudiantes. Los resultados mostraron una relación positiva entre el nivel de actividad física y el rendimiento académico (a mayor actividad física, mayor nota media), al igual que entre el nivel de actividad física y el uso de videojuegos (a mayor nivel de actividad física, mayor uso de videojuegos).AbstractOne of the causes attributable to the reduction of physical activity practice levels in young people is the increase in the use of video games. The aim of this study was to know the relationship between the practice of physical activity, the use of video games and academic performance in university students. Eighty-one students (age = 20 ± 6 years, 42 men and 45 women) belonging to the Degree in Physical Activity and Sports Sciences and the Primary Education Degree participated in the study. Data collection was carried out using the Physician-based Assessment and Counseling for Exercise questionnaires and theVideogamesRelated Experience Questionnaire. Academic performance wasanalysedusing the students' average grade. The results showed a positive relationship between the level of physical activity and academic performance (higher physical activity, higher average grade), as well as between the level of physical activity and the use of video games (higher physical activity level, higher use of video games).

Background: Prevalence of overweight and obesity in adult has increased each year in Indonesia. Middle managers were groups at risk for overweight because their job characteristics such as low physical activity and risk of experiencing job stress. Economy support in middle manager was one of supporting factor which affect to higher amount of energy intake. Overweight in adult can affect on their health status and work productivityObjectives: The purpose of this study was to analyze the correlation between energy intake, job stress, physical activity and sleep duration with BMI in middle manager.Methods: This was an observational study with cross sectional design. 49 Middle Manager in Surabaya’s Government Agency were selected using cluster sampling. Nutritional status data were collected using anthropometric measurement, energy intake using SQ-FFQ, job stress using OSI-R questionnaire, physical activity and sleep duration data using activity recall. Data were analyzed by Pearson product moment test.Results: This study showed that most of respondents has normal nutritional status (61.2%), adequate energy intake (47%), moderate level job stress (69.4%), low (46.9%) and moderate (46.9%) physical activity level, and lack of sleep duration (59.2%). There were correlation between energy intake (p=0.001) and sleep duration (p=0.006) with BMI. Job stress (p=0.227) and phyisical activity (p=0.148) had no correlation with BMI.Conclusions: higher energy intake and lower sleep duration would increase BMI.ABSTRAKLatar Belakang: Prevalensi status gizi lebih pada penduduk dewasa semakin meningkat di Indonesia. Manajer madya merupakan kelompok yang berisiko mengalami kegemukan karena jenis pekerjaan kantor yang ringan serta rentan mengalami stres kerja. Dukungan ekonomi juga menjadi salah satu faktor pendukung besarnya asupan energi dibandingkan energi yang dikeluarkan untuk beraktifitas. Masalah gizi lebih pada penduduk dewasa dapat memengaruhi status kesehatan dan produktifitas kerja seseorang.Tujuan: Tujuan penelitian ini adalah untuk menganalisis hubungan antara asupan energi, stres kerja, aktifitas fisik dan durasi waktu tidur dengan Indeks Massa Tubuh (IMT) pada Manajer Madya.Metode: Penelitian ini adalah observasional dengan desain penelitian potong lintang. Sebanyak 49 manajer madya di Dinas Pemerintah Kota Surabaya dipilih menggunakan metode cluster sampling. Pengumpulan data menggunakan pengukuran antropometri untuk IMT, SQ-FFQ untuk asupan energi, kuesioner OSI-R untuk stres kerja serta recall aktifitas fisik untuk data aktifitas fisik dan durasi waktu tidur. Analisis data menggunakan uji korelasi pearson product moment.Hasil: Penelitian menunjukkan bahwa sebagian besar responden memiliki status gizi normal (61,2%), kecukupan energi tergolong baik (47%), stres kerja tingkat sedang (69,4%), aktifitas fisik ringan (46,9%) dan sedang (46,9%) serta durasi tidur yang kurang (59,2%). Terdapat hubungan antara asupan energi (p=0,001) dan durasi waktu tidur (0,006) dengan IMT. Stres kerja (p=0,227) dan aktifitas fisik (p=0,148) tidak berhubungan dengan IMT.Kesimpulan: Semakin tinggi asupan energi dan semakin singkat durasi waktu tidur maka akan semakin tinggi IMT pada manajer madya.
