RESUMO

BACKGROUND: The prevalence of overweight and obesity, particularly among women, is increasing in Nepal. Previous studies in the South Asia have found television watching to be a risk factor for overweight and obesity among women of reproductive age. However, this association had not been studied in the context of Nepal. This study aims to identify the association between frequency of television watching and overweight and obesity among Nepalese women of reproductive age. METHODS: This cross-sectional study utilized the Nepal Demographic and Health Survey 2016 (NDHS 2016) data. A total weighted sample of 6,031 women were included in the final analyses. The women were 15-49 years of age and were either not pregnant or had not delivered a child within the two months prior to the survey. Body mass index (BMI) was the primary outcome of this study, which was categorized using an Asia-specific cutoff value. Normal and/or underweight was defined as a BMI <23.0 kg/m2, overweight was defined as a BMI between 23.0 kg/m2 and <27.5 kg/m2, and obesity was defined as a BMI ≥27.5 kg/m2. Frequency of watching television was the main independent variable of this study, which was divided into the following three categories: not watching television at all, watching television less than once a week, and watching television at least once a week. Multilevel ordered logistic regression was conducted to find the factors associated with overweight and obesity. A p-value <0.05 was considered significant in the final model. RESULTS: Around 35% of the participants were overweight or obese (overweight: 23.7% and obese: 11.6%). A majority of the study participants was aged between 15 and 24 years (36.5%), and resided in an urban area (63.2%), Province No. 3 (22.3%), and the Terai ecological region (49.5%). Around one-third (34.0%) of the participants received no formal education while an almost similar proportion (35.5%) completed secondary education. Approximately half of the study participants (50.6%) reported watching television at least once a week, whereas more than a quarter (28.7%) of them did not watch television at all. Women who watched television at least once a day had a higher prevalence of overweight and obesity than the other groups (p-value <0.0001). Women who watched television at least once a week were 1.3 times more likely to be overweight or obese in comparison to women who never watched television (Adjusted Odds Ratio (AOR): 1.3, 95% CI: 1.0-1.7; p-value <0.05). In the urban areas, women who watched television at least once a week were 40% more likely to be overweight or obese than those who did not watch television at all (AOR: 1.4, 95% CI: 1.1-1.7; p-value <0.01). No significant association between overweight and obesity and the frequency of viewing television was observed in the rural area. CONCLUSIONS: Watching television at least once a week is associated with overweight and obesity in women of reproductive age living in the urban areas of Nepal. Public health promotion programs should raise awareness among women regarding harmful health consequences of sedentary lifestyle due to television watching.

RESUMO

BACKGROUND: Accurately measuring parents' attitudes and beliefs regarding limiting their children's TV viewing is important to inform the design and evaluation of effective interventions. This manuscript assesses the internal consistency reliability, test-retest reliability, convergent validity, and construct validity of the Model of Goal Directed Behavior (MGDB) scales among parents of Latino preschoolers to characterize Latino parents' attitudes and beliefs toward limiting their preschoolers' TV viewing. METHOD: Participants included parents of Latino preschoolers in the United States, 3-5 years old (n = 186). Parents completed a socio-demographic survey and the 105-item MGDB questionnaire (Attitudes, Perceived Positive/Negative Behavioral Control, Subjective Norms, Positive and Negative Anticipated Emotions, Habits, Self-Efficacy, Desires, and Intentions surrounding their child's TV viewing) which was used to measure internal consistency reliability and construct validity. A subsample of participants completed the questionnaire twice to measure test-retest reliability. Further, parents completed a 7-day TV viewing diary for their preschooler, and a TV parenting practices questionnaire as measures of convergent validity. RESULTS: Internal consistency reliability was generally acceptable for the MGDB scales (Cronbach's alphas> 0.7), except for the Desires scale, which was revealed to have two factors and the Attitudes and Perceived Behavioral Control scales. Test-retest reliability over 2 months had negligible to moderate correlations (r's = 0.28 to 0.61). Two structural equation models were conducted. One yielded acceptable model fit (x2 (97) = 113.65, p = .119) and the other had questionable model fit (x2 (97) = 125.39; p = .028). Testing convergent validity, only two MGDB scales (Habits and Self-Efficacy) were positively correlated with the TV parenting practices questionnaire (r's = 0.33 to 0.51), and none were meaningfully correlated with preschoolers' mean daily TV viewing. CONCLUSIONS: Initial reliability and validity for some of the MGDB scales appear acceptable among parents of Latino preschoolers. Refinement of the instrument and testing among larger samples is necessary to fully evaluate psychometric properties. This instrument may be useful for characterizing Latino parents' attitudes and beliefs toward limiting their preschoolers' TV viewing and informing future TV reduction interventions. TRIAL REGISTRATION: Clinical Trials NCT01216306 Registered October 6, 2010.

RESUMO

OBJECTIVE: Several studies have examined the characteristics of anti-smoking advertisements that are associated with quitting behaviour. Some studies use researchers or graduate students to code advertisement characteristics, while others recruit smokers or members of the general public. The aim of this study was to assist future campaign development by assessing whether anti-smoking advertisement characteristics are coded differently by smokers and 'experts' (individuals with knowledge of health promotion, public health or advertising). METHODS: A total of 49 smokers and 42 experts coded anti-smoking advertisements according to four key characteristics (emotional/cognitive approach, negative/positive tone, message frame, and main message) and the use of eight executional techniques. Chi-squared tests were used to measure differences in coding outcomes between smokers and experts. RESULTS: There were significant differences between smokers and experts in the coding of all key characteristics and four of the eight executional techniques. Compared with smokers, experts were more likely to perceive advertisements as negative in tone and as inducing fear. CONCLUSIONS: Smokers and experts perceived the characteristics of anti-smoking advertisements differently. Implications for public health: Differences between smokers and experts may need to be taken into account where studies use either of these groups to code advertisements for campaign development or evaluation purposes.

RESUMO

OBJECTIVE: To describe advertising of discretionary foods on television at times when children watch television. METHODS: We randomly sampled 84 days (one of each weekday for every month of the year) for 2017, viewed all food advertisements and categorised them according to type (healthy, discretionary or other). The frequency of advertisements per hour was calculated for times when most children watch television (peak viewing time PVT1) and when C-rated programs can be broadcast (PVT2). RESULTS: The rate of advertising of discretionary foods during PVT1 was 1.5/hour (95%CI 1.4-1.5), and during PVT2 was 1.7/hour (1.6-1.8). CONCLUSIONS: Children continue to be exposed to food advertising. Implications for public health: Voluntary food and grocery industry codes have not prevented children from being exposed to discretionary food advertising on television. From June 2019, all food and beverage advertising is subject to either food industry or advertising industry codes. The data presented here will form the baseline for future evaluation of whether the new arrangements reduce children's exposure to food advertising.

RESUMO

BACKGROUND: Both screen time and metabolic syndrome (MetS) are associated with health outcomes. However, limited data exist on the association between screen time and MetS among expatriate adolescents living in United Arab Emirates (UAE). METHODS: We conducted a cross-sectional school-based study on 473 expatriate adolescents (47% girls) aged 12-18 years in Al-Ain district of Abu Dhabi Emirates in the UAE. Data was collected with the expertise of trained nurses & IDF criteria was used to define MetS. Information on screen time (computer, television, and video game use combined) during a regular day was self-reported, and divided into two categories: <2, or ≥2 h per day. Using logistic regression analyses, adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated for the association between screen time and MetS. RESULTS: A high proportion of adolescents (75.3%) spent ≥2 h daily on screen. The prevalence of MetS was 8.5% in those with <2 h per day of screen time compared with 13.5% in those who reported ≥2 h per day. There was a graded positive association between screen time and MetS (P-trend = 0.01). Each hour increase in screen time was associated with 21% (OR, 1.21; 95% CI, 1.08-1.35) greater likelihood of having MetS. The adjusted OR value associated with ≥2 h of daily screen time was 2.20 (95% CI, 1.04-4.67), compared with adolescents who spent less than 2 h of daily screen time. CONCLUSION: Higher screen time by expatriate adolescents was associated with increased likelihood of having MetS.

RESUMO

BACKGROUND: Sedentary behaviors are prevalent in Chinese children, however, the studies on their trends and socioeconomic disparities are scarce. We examined the time trends of daily television (TV) viewing and video game playing and the associated socioeconomic factors in Chinese children in Hong Kong, the most developed and westernized city in China. METHODS: In a panel data study involving 538,300 primary four and 510,294 primary six students from 1999/2000 to 2008/09, data on socioeconomic status, sedentary behaviors (TV viewing and video game playing) and other lifestyle habits were collected using a self-administered questionnaire. Trends in sedentary behaviors over time were assessed. Their socioeconomic disparities were examined by interactions in generalized estimating equations with the adjustment for weight status and extracurricular physical activities. RESULTS: The age and sex-standardized prevalence of ≥2 h daily TV viewing decreased from 51.4% (95% confidence interval [CI] 51.1-51.8%) in 1999/2000 to 43.8% (95% CI 43.4-44.2%) in 2008/09 (P for trend < 0.001), whereas that of ≥1 h daily video game playing increased from 8.2% (95% CI 7.9-8.4%) to 22.4% (95% CI 22.0-22.7%). Both sedentary behaviors were more prevalent in boys than girls, but the disparities decreased over time (Ratio of odds ratio [ROR] = 0.996 and 0.924 for TV viewing and video game playing, respectively). In contrast, both sedentary behaviors were increasingly more prevalent in children whose parents had lower education levels or non-managerial/professional occupations (ROR 1.006-1.082). CONCLUSIONS: Children in lower socioeconomic families in Hong Kong were increasingly at risk of having sedentary behaviors over years and thus deserve more attention. Effective strategies targeting children and/or their parents of lower socioeconomic status are needed to reduce sedentary behaviors.

RESUMO

BACKGROUND: Data suggest that sedentary behavior is an independent risk factor for obesity; however, the extent to which physical activity (PA) and sex alter this relationship remains unclear. To address this gap, the current study examined the association between television (TV) viewing time and percent body fat (%BF) as a function of PA level and sex. METHODS: Trained interviewers assessed 454 adults at their place of residence. Participants completed questionnaires to determine h of TV watched per week, PA level (inactive = not meeting PA guidelines vs. active = meeting PA guideline), and covariates including demographics (e.g., sex), depression symptoms, perceived stress, fruit and vegetable intake, and environmental support for PA. Foot-to-foot bioelectrical impedance (Tanita TBF-300, Tokyo, Japan) was used to assess %BF. Mixed models were generated to examine the association between TV h/wk. and %BF as a function of PA level and sex while accounting for the multi-level nature of the data (neighborhood- and individual-levels) and covariates. RESULTS: Participants were 44.4 ± 14.0 (Mean + Standard Deviation) years of age with 33.2 ± 11.1%BF, and watched 19.3 ± 15.5 h/wk. of TV. Most were female (70.9%) and inactive (63.2%). Mixed model regression demonstrated that among inactive participants, each additional h of TV viewed/wk. was associated with a 1.03% increase in %BF; TV h/wk. and %BF were not associated in active adults. When models were further stratified by sex, h of TV viewed/wk. were significantly associated with %BF only in inactive females. Each additional h of TV viewed/wk. was associated with an increase in %BF of 1.14%. CONCLUSION: Interventions targeting PA and/or TV viewing time may be a high-priority to curb excess BF accumulation especially among inactive females.

RESUMO

Promotion of breast milk substitutes (BMS) and inappropriate marketing of commercially produced complementary foods (CPCF), including through television, can negatively influence infant and young child feeding. The World Health Organization International Code of Marketing of Breast-milk Substitutes and subsequent relevant World Health Assembly (WHA) resolutions prohibit such advertising and require manufacturers and distributors to comply with its provisions; however, such regulations at national level may vary. Advertisements require Ministry of Health approval in Cambodia but are not regulated in Senegal. Television stations were monitored for 13 months in Phnom Penh and for 3 months in Dakar to assess advertisements for BMS and CPCF. Ten television channels (out of 16) in Phnom Penh and four (out of 20) in Dakar aired advertisements for BMS. Three and five channels, respectively, aired advertisements for CPCF. All BMS advertised in Phnom Penh were for children over 1 year of age. BMS products for children 6+ months of age and 1+ years of age were advertised in Dakar. Average air time for BMS advertisements was 189.5 min per month in Phnom Penh and 29.7 min in Dakar. Air time for CPCF advertisements averaged 3.2 min per month and 13.6 min, respectively. Fewer than half of BMS advertisements and three quarters of CPCF advertisements explicitly stated an age of use for products. Nutrition and health claims were common across BMS advertisements. This study illustrates the need to adopt, regulate, monitor, and enforce legislation prohibiting BMS promotion, as well as to implement regulations to prevent inappropriate promotion of CPCF.

RESUMO

The study explore television influence as one of the most powerful translators of the mankind socio-cultural needs of a personality, in a sample of 1030 participants aged 18 to 35 years. Within the framework of the study five TV programs blocks, which have been allocated according to the audience's interest criterion. Clarification of the differences in the emotional orientation of the defined segments allowed to characterize the peculiarities of their motivating needs. It was determined that the segment of the entertaining television programs block is characterized by the desire to feel bodily-emotional comfort, accumulation of material wealth and lack of the desire for communication; the segment of the contemplative block is very similar to the first one, but they are different with their latent desire for self-realization in communication; the segment of the activity-related block does not want to experience any emotions; the cognitive segment, conversely, wants to experience emotions of all kinds, except for hedonistic and acquisition; for the segment of the informational block the acquisition emotions are the most desirable, knowledge or information accumulation are unwanted. The results of this study can be used to correct the viewing content and to develop new television projects with a view to their positive impact on the personality formation

RESUMO

BACKGROUND: How the mainstream news media report violence against women is significant if levels of violence are to be reduced and ultimately eliminated. Media reporting is an important indicator through which to measure progress towards shifting social and cultural norms that reinforce or challenge the place of violence against women in our society. The current study, therefore, aimed to establish a baseline picture of the extent and nature of reporting of violence against women by the mainstream Australian news media. METHODS: Descriptive and content analysis of media reports on violence against women that were collected over four months in three states of Australia. Reports were from newspapers, broadcast (television and radio) and online news sites. RESULTS: Coverage of violence against women in the mainstream news media was extensive. Explicitly situating violent experiences for women within a broader social context was infrequent. Few news reports included information for women on where to seek help. Additionally, news reports rarely elevated the voices of survivors, advocates and other experts, with a disproportionate emphasis on law enforcement, political and criminal justice perspectives. CONCLUSIONS: Despite readiness among journalists and readers to engage in news about violence against women, reporting that promotes public understanding of the issue is not always the norm.

RESUMO

The expanding sources of media coverage of cancer may have a powerful impact on emotions, cancer knowledge, information seeking, and other health behaviors. We explored whether television advertisements were associated with cancer worry, perceived risk, and perceived ability to prevent cancer using cross-sectional data from the Health Information National Trends Survey (HINTS) linked to television advertisement data from Kantar Media. We conducted hierarchical linear modeling assessing 2-level models for each of the 3 outcomes of interest. The most common content included advertisements for cancer clinics (54.4%), public service announcements about cancer (22.0%), and advertisements about cancer organizations (9.1%). Most variance in cancer perceptions was due to individual-level characteristics and not exposure to television advertisements, which aligns with previous literature suggesting a small, but significant, association of television exposure with health beliefs. Higher levels of exposures to cancer-specific television advertisements were associated with higher levels of risk perceptions. Additionally, older adults' levels of perceived worry and risk were more likely to be associated with television exposure than younger adults. Given the substantial investments being made in cancer advertisements on television, the differences in exposure are important to consider in future efforts to understand predictors of beliefs about cancer and in the development of interventions designed to target risk-reducing behaviors.

RESUMO

DIBR-3D technology has evolved over the past few years with the demands of consumers increasing in recent times for future free-view 3D videos on their home televisions. The main issue in 3D technology is the lack of 3D content available to watch using the traditional TV systems. Although, some sophisticated devices like stereoscopic cameras have been used to fill the gap between the 3D content demand and 3D content supply. But the content generated through these sophisticated devices can not be displayed on the traditional TV systems, so there needs to be some mechanism which is inline with the traditional TV. Furthermore, the huge collection of existing 2D content should be converted to 3D using depth image-based rendering techniques. This conversion technique can highly contribute in overcoming the shortage problem of the 3D content. This paper presents a novel approach for converting 2D degraded image for DIBR 3D-TV view. This degraded or noisy/blur image is enhanced through image dehazing and Directional Filter Bank (DFB). This enhancement is necessary because of the occlusion effect or hole filling problem that occurs due to imperfect depth map. The enhanced image is then segmented into the foreground image and the background image. After the segmentation, the depth map is generated using image profiles. Moreover, Stereoscopic images are finally produced using the DIBR procedure which is based on the 2D input image and the corresponding depth map. We have verified the results of the proposed approach by comparing the results with the existing state-of-the-art techniques.

RESUMO

OBJECTIVES: The purpose of this study was to investigate the impacts of television (TV) viewing and bedroom TV presence on young children's sleep as measured by actigraphy. DESIGN: Analyses of covariance were run to examine differences in sleep duration and quality among children based on the presence of TVs in their bedrooms and the amount of TV watched. SETTING: Recruited in preschools in Massachusetts; recorded ambulatory (in home, environs). PARTICIPANTS: Participants were 470 children between 33 and 71 months of age (M = 51.02). MEASUREMENTS: Children were instructed to wear an actigraph watch for 16 days. Caregivers reported demographic information, completed behavior questionnaires, and answered questions regarding their child's TV use. RESULTS: Children who watched more TV and had TVs in their bedroom displayed significantly shorter sleep duration and worse sleep, but they also napped significantly longer in the daytime. Nonetheless, total 24-hour sleep was shorter for those who watched more TV and had TVs in their bedroom compared to those who did not have TVs in their bedrooms or watch TV frequently. Children who had TVs in their bedrooms watched TV later at night, watched more adult TV programs, and had higher negative affect than children without TVs in their bedrooms. CONCLUSIONS: These findings suggest that TV use in young children does impact sleep duration and quality as measured by actigraphy, and daytime napping does not offset these negative impacts.

RESUMO

BACKGROUND: Both physical activity (PA) and TV-viewing are associated with depressive symptoms, but the combined association with depressive symptoms is unclear. Therefore, our aim was to analyze the joint association of PA and TV-viewing with depressive symptoms among a large cohort of adults. METHODS: We used data from the Brazilian National Survey, conducted in 2013 with 59,401 adults [≥18 years (34,282 women)]. Information regarding exposures (TV-viewing and leisure PA), outcome (depressive symptoms) and covariates (chronological age, race, educational status, employment status, tobacco smoking, alcohol consumption) were self-reported. Body mass index was estimated through the assessment of body mass and stature. Logistic regression models were used. RESULTS: Engaging in >5 hours of TV viewing was associated with elevated depressive symptoms [13.1% (CI95%: 11.6%-14.7%) vs. 7.4% (95%CI:7.0%-7.8%)]. However, this association was nullified when people met guidelines and engaged in >150 min of PA per week. Specifically, among men [Active: OR = 1.16 (95%CI: 0.58-2.32) vs. Inactive: OR = 3.63 (95%CI: 2.43-5.42)] and women [Active: OR=1.30 (95%CI: 0.80-2.11) vs. Inactive: OR = 1.84 (95%CI: 1.43-2.36)]. CONCLUSION: Whilst TV viewing is associated with increased depressive symptoms, meeting recommended physical activity levels reduces the association between TV-viewing and depressive symptoms.

RESUMO

The scope of this article is to analyze the temporal trend of the consumption of fatty meats and factors associated with the consumption thereof between 2007 and 2014. A time series of fatty meat consumption (red meat and chicken) was conducted by the "Surveillance of Risk and Protection Factors for Chronic Diseases (Vigitel) telephone survey." The consumption trend was analyzed by joinpoint regression and expressed in annual percentage variation (VPA [95% CI]), while sociodemographic and behavioral factors were associated in 2007 and 2014 by the generalized linear (log-binomial) model. Between 2007 and 2014, white meat consumption ≥ 5x/ week increased (VPA 6.9% [5.7, 8.1]), while red meat consumption remained stable. Fatty meat consumption showed a significant reduction as of 2011 (VPA -4% [-7.5; -0.2]), probably due to the reduction in the consumption of fatty red meats. It was found that males, of younger age groups living in the center-west/south-east/south regions, with low education level and alcohol and tobacco abuse were associated with fatty meat consumption; while watching television>3hours/day was only associated in 2014. The consumption of fatty meats showed a reduction trend in the Brazilian population, and its consumption was associated with sociodemographic and behavioral variables.

RESUMO

Physical activity (PA) is a potential modifiable correlate of the age-related decline in sexual function, but no studies have explicitly tested this. This study aimed to examine associations between PA, television viewing (TV) time and sexual activity, problems, and concerns. Data were from 7,038 men and women aged ≥50 years participating in the English Longitudinal Study of Ageing. PA and TV viewing time were self-reported. Sexual behaviour and concerns were assessed by self-completion questionnaire. Covariates included age, partnership status, socio-economic status, limiting long-standing illness, smoking status, alcohol intake and depressive symptoms. The odds of reporting any sexual activity were increased among individuals who participated in moderate (OR = 1.64, 95% CI: 1.24⁻2.15 in men) or vigorous (OR = 2.06, 95% CI: 1.50⁻2.84 in men, OR = 1.42, 95% CI: 1.09⁻1.85 in women) PA at least once a week. Erectile difficulties were less common among men who were active (OR = 0.58, 95% CI: 0.44⁻0.77 for vigorous PA). Women who watched ≥6 hours of TV/day had lower odds of thinking about sex frequently (OR = 0.69, 95% CI: 0.50⁻0.96) or, if they did not live with a partner, being sexually active (OR = 0.40, 95% CI: 0.22⁻0.72). Encouraging older adults to be more physically active could help to improve sexual relationships and, as a result, mental health and wellbeing.

RESUMO

BACKGROUND: Few studies have investigated the association between screen viewing (SV) and sleep duration among young children. This study aims to examine the association between total and device-specific SV and sleep duration among children aged 2 and below. METHODS: We conducted a cross-sectional study of 714 Singaporean children aged 2 years and below. Parents were recruited during routine well-child clinic visits from two national polyclinics. In Singapore, all parents visit well-child clinics with their children at regular intervals for routine check-ups and vaccinations. Socio-demographic characteristics, duration of total and device-specific SV, and sleep duration were reported by parents via interviewer-administered questionnaires. Multiple linear regression analysis was used to assess associations between various types of SV and sleep duration, adjusted for socio-demographic variables. Due to significant interaction between SV and age, stratified analyses for children aged less than 6 months and those aged 7-24 months were performed. RESULTS: The prevalence of daily SV among children was 53.1%; 28.3% in children up to 6 months and 73.8% in children aged 7 to 24 months. TV viewing was reported for 44.3% of all children and mobile device SV for 30.1%. Children's average sleep duration was 13.9 (SD = 3.5) hours daily and younger children had longer sleep duration than older ones (up to 6 months: mean = 15.6 h, SD = 3.9; 7-24 months: mean = 12.4 h, SD = 2.2; P < 0.01). In the regression analysis among all children, each 1 h per day increment in total SV was significantly associated with 0.26 h shorter sleep duration with similar significant associations for TV (ß = - 0.28 h, 95%CI: -0.50, - 0.06) and mobile devices (ß = - 0.35 h, 95%CI: -0.61, - 0.09). Stratified analysis revealed significantly greater reductions in sleep with higher SV among children aged 6 months and below (ß = - 0.73 h, 95%CI: -1.12, - 0.34), while associations were weaker in older children (ß = - 0.13 h, 95% CI: -0.24, - 0.01). CONCLUSIONS: This study provides evidence for a substantial association between longer SV and shorter sleep duration among very young children. These associations appeared stronger among children aged 6 months and below as compared with those aged 7 to 24 months. Further studies are warranted to confirm our findings.

RESUMO

OBJECTIVES: To examine the association of sedentary behavior (SB) with metabolic syndrome (MetS) in adults, as well as to identify the impact of physical inactivity and economic condition on such association. STUDY DESIGN: This is a cross-sectional study. METHODS: This study was conducted in the city of Bauru, São Paulo State, Brazil (n = 970). Television (TV) viewing and physical activity (PA) were assessed by questionnaire. MetS was assessed via medical records. Descriptive statistics and binary logistic regression were used in data analyses. RESULTS: Participants with moderate TV viewing were associated with MetS when compared with low TV viewing group, even after adjustments for age, sex, economic status, smoking, and PA (odds ratio [OR] = 1.49 [95% confidence interval {CI}: 1.01-2.20]). The fully adjusted model showed an association between high exposure to TV viewing with MetS (OR = 1.77 [95%CI: 1.11-2.82]). The combination of physical inactivity and high TV viewing boosted the likelihood of having MetS (OR = 1.89 [95%CI: 1.08-3.29]). CONCLUSION: The results of the present study suggest that moderate and high TV viewing time is associated with the presence of MetS, mainly in insufficiently active adults and those living in lower economic condition.
