Efficacy of audiovisual distraction using eyeglasses during dental care: a randomized clinical trial.

This randomized parallel-group control trial tested the efficacy of distraction using audiovisual eyeglasses (AVE) during dental procedures [NCT03902158]. Forty-four 6-9 year-old children with low/moderate anxiety and who needed restorative treatment or exodontia of the primary molars were randomly allocated into two groups: the AVE (experimental) and the conventional behavior management techniques (control) groups. Motion sensors were used to measure the participants' body movements. Dental visits were video recorded, and their pain levels and behavior were assessed using the Faces, Legs, Activity, Cry, and Consolability Behavioral Pain Assessment Scale and the Venham Behavioral Scale, respectively. Anxiety was assessed via heart rate measurements. After treatment, the children scored their pain using the Faces Pain Scale. Mann-Whitney U and chi-square tests were used to compare the groups. The mean score on the behavioral scale was 0.59 in the experimental group and 0.72 in the control group under local anesthesia (p = 0.73). During the procedure, the mean score was 0.41 in the experimental group and 1.32 in the control group (p = 0.07). The mean heart rate was similar in both groups (p = 0.47), but a significant increase during treatment was observed in the control group. There was no difference between the groups in terms of pain, behavior, and self-reported pain scores (p = 0.08). Children aged 6-7 who used the AVE had fewer wrist movements (435.6) than that of children in the control group (1170.4) (p = 0.04). The AVE achieved similar results to the basic behavior management techniques, with good acceptance by the children.

Association of Pain, Severe Pain, and Multisite Pain with the Level of Physical Activity and Sedentary Behavior in Severely Obese Adults: Baseline Data from the DieTBra Trial.

The study aimed to assess the prevalence of pain, severe pain, and pain in four or more regions associated with physical activity and sedentary behavior, as well as other associated factors in severely obese adults (Body Mass Index ≥ 35 kg/m2). Baseline data from the DieTBra Trial were analyzed. The outcome variables were pain (yes/no) and pain in four or more sites (yes/no), as identified by the Brazilian version of the Nordic Musculoskeletal Questionnaire, along with the presence of severe pain (yes/no), identified based on the Numerical Pain Rating Scale (≥8). The main independent variables were moderate to vigorous physical activity (MVPA), light physical activity, and sedentary behavior, assessed by triaxial accelerometry. The variables were analyzed using multiple hierarchical Poisson regression. In 150 individuals (men, 14.67%; and women, 85.33%), with a mean age of 39.6 ± 0.7 years, there was a high prevalence of pain (89.33%), severe pain (69.33%), and pain in four or more regions (53.33%). The associated factors were shorter MVPA time with pain (p = 0.010); arthritis/arthrosis (p = 0.007) and the use of muscle relaxants (p = 0.026) with severe pain; and economic class C (p = 0.033), and economic class D (p = 0.003), along with arthritis and arthrosis (p = 0.025) with pain in four or more sites. There were no significant associations between sedentary behavior and any of the three outcomes analyzed. These findings indicate that, in severely obese individuals, shorter MVPA time is associated with a higher prevalence of pain. Future studies on physical activity intervention may contribute to the reduction in the prevalence and severity of pain in adults with severe obesity.

How many days are needed to estimate wrist-worn accelerometry-assessed physical activity during the second trimester in pregnancy?

BACKGROUND: Objective methods to measure physical activity (PA) can lead to better cross-cultural comparisons, monitoring temporal PA trends, and measuring the effect of interventions. However, when applying this technology in field-work, the accelerometer data processing is prone to methodological issues. One of the most challenging issues relates to standardizing total wear time to provide reliable data across participants. It is generally accepted that at least 4 complete days of accelerometer wear represent a week for adults. It is not known if this same assumption holds true for pregnant women. AIM: We assessed the optimal number of days needed to obtain reliable estimates of overall PA and moderate-to-vigorous physical activity (MVPA) during the 2nd trimester in pregnancy using a raw triaxial wrist-worn accelerometer. METHODS: Cross-sectional analyses were carried out in the antenatal wave of the 2015 Pelotas (Brazil) Birth Cohort Study. Participants wore the wrist ActiGraph wGT3X-BT accelerometer for seven consecutive days. The daily average acceleration, which indicated overall PA, was measured as milli-g (mg), and time spent in MVPA (minutes/day) was analyzed in 5-minute bouts. ANOVA and Kruskal-Wallis tests were used to compare variability across days of the week. Bland-Altman plots and the Spearman-Brown Prophecy Formula were applied to determine the reliability coefficient associated with one to seven days of measurement. RESULTS: Among 2,082 pregnant women who wore the accelerometer for seven complete days, overall and MVPA were lower on Sundays compared to other days of the week. Reliability of > = 0.80 to evaluate overall PA was reached with at least three monitoring days, whereas seven days were needed to estimate reliable measures of MVPA. CONCLUSIONS: Our findings indicate that obtaining one week of accelerometry in adults is appropriate for pregnant women, particularly to obtain differences on weekend days and reliably estimate overall PA and MVPA.

Metabolic equivalent of task (METs) thresholds as an indicator of physical activity intensity.

The purpose of the study was to identify and compare validity parameters of different absolute intensity thresholds in METs, using relative intensity classification as criterion measure. Convenience sampling was used to recruit total of 112 adults. The participants carried out an incremental maximal cycle ergometer test and asked to perform nine free-living activities. The oxygen uptake was measured by a VO2000® gas analyser throughout the tests. The intensity thresholds were identified using Receiver Operator Characteristic (ROC) curve analysis, having relative intensity categories as criterion measure. A total of 103 participants attended the two visits. Among 54 men and 49 women, the mean (± SD) ages were 36.1 (± 11.1) and 33.9 (± 10.6) years, respectively. The intensity thresholds identified were 4.9 METs for moderate and 6.8 METs for vigorous physical activity. In conclusion, the physical activity thresholds, generated according to the entire sample, were higher and presented improved specificity when compared to thresholds currently recommended. Moreover, these parameters presented relatively high accuracy, even when applied to specific groups such as sex, age, nutritional status and physical fitness.

Physical activity and perceived insecurity from crime in adults: a population-based study.

BACKGROUND: The present study aimed to describe the perception of safety from crime in the neighborhood and to evaluate its association with leisure-time and transport-related physical activity in adults. METHODS: A cross-sectional population based study was conducted in the urban area of Pelotas, Brazil, in 2012. Perceived insecurity from crime in the neighborhood was measured using the Neighborhood Environment Walkability Scale (NEWS) and the City Stress Inventory (CSI). Physical activity was measured using an adapted version of the leisure and transportation sections of the long version of the International Physical Activity Questionnaire. RESULTS: Overall, 52.3% (95%CI49.0; 55.6) of the participants reported perceived exposure to an unsafe neighborhood. Subjects who practiced 150 or more minutes per week of physical activity during leisure-time and transportation were 10.5% (95%CI9.0; 12.0) and 51.7% (95%CI 48.7; 54.7), respectively. There were no significant associations between physical activity (leisure-time or transport-related) and perceived insecurity from crime, neither in unadjusted nor in adjusted analyses. CONCLUSION: There was no evidence that the perception of safety from crime is associated to higher physical activity levels among Brazilian adults.

Fontes de informacao sobre a importancia da atividade fisica: estudo de base populacional / Sources of information on the benefi ts of physical activity: population-based study

A comunidade cientifica esta ciente dos efeitos positivos da atividade fisica na prevencao de doencas cronicas e na promocao da saude. No entanto, pouco se sabe sobre as fontes de informacao populacionais referentes a pratica de atividade fisica. O objetivo do estudo foi investigar as fontes de informacao sobre a importancia da atividade fisica em adultos. Foram entrevistadas 972 pessoas com idade entre 20 e 69 anos, selecionados por amostragem aleatoria, da zona urbana de Pelotas-RS. As fontes de informacao presentes como opcoes de resposta no questionario eram: televisao, revista, professor de educacao fisica, medico e outros. Dos entrevistados, 76,1% relataram ter recebido alguma informacao sobre a importancia da atividade fisica a saude. A televisao (27,5%) foi o principal meio de divulgacao da pratica de atividade fisica, seguido do professor de Educacao Fisica (22,1%), do medico (18,4%) e de outros (25,7%). Um quinto da amostra nao recebeu nenhuma informacao referente a pratica de atividade fisica, e apesar de esforcos dos profissionais da area da saude, a televisao ainda e o principal veiculo de divulgacao.

The scientific community is currently aware of the benefi cial eff ects of physical activity practice both for preventing chronic diseases and for promoting health. However, little is known on the sources of information on the benefi ts of physical given to the population. The aim of the present study was to investigate the sources of physical activity advice in adults. We interviewed 972 individuals aged 20-69 years of age, who were selected through a multistage random sampling strategy in the urban area of Pelotas, Brazil. The potential sources of physical activity advice included in the questionnaire were: television, magazines, physical education teacher, physicians and others. Out of the subjects included, 76.1% reported to have received physical activity advice at least once. The television (27.5%) was the most frequently reported source of such advice, followed by physical education teachers (22.1%), physicians (18.4%) and others (25.7). One fifth of the population did not receive advice on physical activity, and in spite of the efforts of health professionals, the television is still the main source of physical activity advice at the population level.
