RESUMO
Depressive symptoms have a strong effect on appetite decline in older adults. There is also an association between social activity and decreased depressive symptoms, but the mechanism between appetite and social activity with respect to depressive symptoms is unclear. This cross-sectional study examined the direct and indirect effects of social activity on appetite, via depressive symptoms. A total of 259 community-dwelling older adults (mean age 75.1 ± 5.3 years; 55% female) completed the Council on Nutrition Appetite Questionnaire (CNAQ) and the 15-item version of the Geriatric Depression Scale (GDS). We used a cutoff score of 6 on the GDS-15 to determine whether participants displayed depressive symptoms. Social activity was assessed based on the number of activities participated in at least 1-3 times per month. The types of social activity consisted of local community, hobby, sports, citizen, industry, religion, volunteer, and others. Other assessed factors included age, sex, education, financial status, living situation, and comorbidities. To examine the relationships among social activity, depressive symptoms, and appetite, structural equation modeling (SEM) was used, adjusting for variables associated with depressive symptoms or appetite in multivariate analyses. SEM revealed that participation in more types of social activity had a significant indirect effect on higher appetite score via less having depressive symptoms (ß = 0.04, p = 0.018). Our findings suggest that active participation in social activities may have a positive effect on good appetite via not having depressive symptoms among older adults. Further longitudinal or intervention studies are needed to confirm our findings.

PURPOSE: Persistent low back and pelvic pain (LBPP) is a postpartum-specific health problem. Sleep disturbances' association with persistent LBPP is not yet clear. We aimed to examine the cross-sectional association between sleep disturbance and persistent LBPP at 4 months postpartum. METHODS: We enrolled 120 women with LBPP during pregnancy (mean age, 31.8; standard deviation, 4.9 years). The primary outcome was persistent LBPP. We assessed LBPP severity at 4 months postpartum using the Numerical Rating Scale (NRS), where women with an NRS score of ≥ 4 at 4 months postpartum were allocated to the persistent LBPP group. We assessed sleep disturbance at 4 months postpartum using the Japanese version of the Pittsburgh Sleep Quality Index with a total score of ≥ 6 indicating sleep disturbance. Moreover, we performed univariate and multiple logistic regression analyses to examine the cross-sectional association of sleep disturbance with persistent LBPP. The relevant confounding variables were age, body mass index, parity, and history of LBPP before pregnancy. RESULTS: Among the 120 women, 45 women had persistent LBPP (37.5%) with 32 (71.1%) of them reporting sleep disturbance. There was a significant association of sleep disturbance with persistent LBPP (odds ratio [OR], 2.81; 95% confidence interval [95% CI], 1.28-6.19), which remained after adjustments for confounding variables (OR, 2.98; 95% CI, 1.31-6.75). CONCLUSION: Our findings indicate that sleep disturbance is associated with persistent LBPP at 4 months postpartum; therefore, it should be taken into consideration in postpartum women with persistent LBPP.

OBJECTIVE: Kinesiophobia (i.e., fear of movement caused by pain) is increasingly acknowledged as a determinant of disuse among patients with chronic musculoskeletal pain. Kinesiophobia may affect life space-a crucial indicator of an active lifestyle among older people. This study aimed to investigate the previously unexamined association between kinesiophobia and life space among community-dwelling older people with chronic musculoskeletal pain. DESIGN: Cross-sectional study. SETTING: Community. SUBJECTS: We analyzed data from 194 community-dwelling older people (age ≥65 years, mean age = 75.7 years, 71.6% women) with chronic musculoskeletal pain. METHODS: Kinesiophobia, life space, and pain severity were assessed using the Tampa Scale for Kinesiophobia, Life Space Assessment, and Brief Pain Inventory. Linear regression models were applied to analyze the associations between kinesiophobia and life space, and pain severity and life space. RESULTS: In our sample, the prevalence rates for chronic musculoskeletal pain were 10.82% (N = 21) for neck, 55.15% (N = 107) for lower back, 25.26% (N = 49) for shoulder, and 50.00% (N = 97) for knee. The results suggest that higher kinesiophobia is associated with smaller life space (adjusted beta = -0.91, 95% CI = -1.43 to -0.45, P < 0.001), even after adjustment for age, gender, years of education, pain severity, and presence of comorbidity. On the contrary, no significant association between pain severity and life space was observed (adjusted beta = -0.61, 95% CI = -2.92 to 1.72, P = 0.624). CONCLUSIONS: Our findings suggest that kinesiophobia plays an important role in the determination of life space among older people with chronic musculoskeletal pain.

OBJECTIVE: Physical inactivity is recognized as a pandemic health problem. The association of pain with physical activity, particularly when measured objectively, in older adults is unclear. This study investigates the association of number of chronic musculoskeletal pain sites and pain severity with objectively measured physical activity in community-dwelling older adults. DESIGN: Observational study. SETTING: Community. SUBJECTS: We analyzed 267 community-dwelling older adults (mean age = 75.3 years, 67.0% women). METHODS: Number of chronic musculoskeletal pain sites and pain severity were measured using a self-reported questionnaire. Mean steps per day and mean minutes of light physical activity per day and moderate to vigorous physical activity per day were measured using an accelerometer. Linear regression models were applied to analyze the association of number of chronic musculoskeletal pain sites and pain severity with physical activity. RESULTS: The results suggest that a higher number of chronic musculoskeletal pain sites is associated with lower step count (beta = -333.5, 95% confidence interval = -655.9 to -11.0, P < 0.05) and moderate to vigorous physical activity (beta = -2.5, 95% confidence interval = -4.7 to -0.4, P < 0.05) even after adjustment for age, gender, years of schooling, obesity, alcohol habits, smoking status, number of comorbidities, recent surgery, and depressive symptoms. CONCLUSIONS: Our results suggest that the number of chronic musculoskeletal pain sites is associated with low physical activity in older adults. Therefore, low physical activity due to chronic musculoskeletal pain should not be overlooked.

BACKGROUND: Although some gait parameters from inertial sensors have been shown to be associated with important clinical issues, because of controversial results, it remains uncertain which parameters for which axes are clinically valuable. Following the idea that a comprehensive score obtained by summing various gait parameters would sensitively reflect declines in gait performance, we developed a scoring method for community-dwelling older adults, the Comprehensive Gait Assessment using InerTial Sensor score (C-GAITS score). The aim of this study was to examine the internal consistency and the construct validity of this method. METHODS: In this cross-sectional study, the gait performance of 378 community-dwelling older people (mean age = 71.7 ± 4.2 years, 210 women) was assessed using inertial sensors attached to the heel and lower trunk. Participants walked along a 15-m walkway, and accelerations, angular velocity, and walking time were measured. From these data, walking speed, mean stride time, coefficients of variation of stride time and swing time, and autocorrelation coefficients and harmonic ratios of acceleration in vertical, mediolateral, and anteroposterior directions at the lower trunk were calculated. Scoring was performed based on quartile by gender (i.e., scored from 0 to 3) for each of the 10 gait parameters. The C-GAITS score was the sum of these scores (range: 0-30). Lower extremity strength, balance function, fall history, and fear of falling were also assessed. RESULTS: An exploratory factor analysis revealed that the C-GAITS score yielded four distinct factors explaining 57.1% of the variance. The Cronbach's alpha coefficient was 0.77. A single linear regression analysis showed a significant relationship between total C-GAITS score and walking speed (adjusted R2 = 0.28). Results from bivariate comparisons using unpaired t-tests showed that the score was significantly related to age (p = 0.002), lower extremity strength (p = 0.007), balance function (p < 0.001), fall history (p = 0.04), and fear of falling (p < 0.001). CONCLUSIONS: Good internal consistency and appropriate construct validity of the C-GAITS score were confirmed among community-dwelling older adults. The score might be useful in clinical settings because of ease of use and interpretation and capability of capturing functional decline.

BACKGROUND: This study investigated the effect of different components of screen time (mobile phone use, TV/video viewing, and video gaming) on cardiorespiratory fitness (CRF) development in children aged 9-12 years. METHODS: This was a two-year longitudinal study conducted with 175 children (49.7% girls, mean age = 9.5) in Japan. CRF was assessed using a 20 m shuttle run test conducted at baseline and again at follow-up. Children were categorized as "Good" or "Poor" based on the change in CRF scores for each gender. Screen time was assessed using a self-reported questionnaire at baseline and termed as "high" if children reported ≥ 2 h/day. Univariate and multivariate logistic regression analyses were performed after adjusting for gender, physical activity, and time of data collection. RESULTS: Children scoring "high" on mobile phone use had lower odds of being categorized as "Good" in CRF change (crude odds ratio (OR): 0.34; 95% confidence interval (CI): 0.15-0.90 (adjusted OR: 0.33; 95% CI: 0.12-0.91)). There were no significant effects of TV/video viewing (crude OR: 1.54; 95% CI: 0.84-2.81) and video gaming (crude OR: 0.98; 95% CI: 0.48-1.97) on changes in CRF. CONCLUSIONS: Limiting excessive mobile phone usage might be important for ensuring healthy development of CRF in children.
RESUMO
This study aimed to investigate whether abnormal gait patterns are associated with experiencing an elevated degree of pain after daily walking. In this preliminary, cross-sectional study, 223 community-dwelling older adults were assessed for pain experienced after daily walking using a simple question that involved asking the subject about their past experiences of an elevated degree of pain after walking for 400 m or more. Gait patterns were assessed using the Comprehensive Gait Assessment using InerTial Sensor score (C-GAITS score), derived from the data measured by Inertial sensors attached to the lower trunk and heel when subjects walked along a 15 m walkway at a self-selected preferred speed. The score was the sum of 10 gait parameter scores. The lower scores indicated more and worse abnormal gait patterns. In total, 24 older adults (10.8%) reported that they experienced pain after daily walking. According to the multiple logistic regression analyses, older adults with a lower total C-GAITS score had a significantly greater probability of having past experiences of pain after walking (odds ratio = 1.11, 95% confidence interval = 1.03-1.20). The findings of this study suggest that more and worse abnormal gait patterns among older adults in a clinical walking test are associated with an elevated degree of pain after daily walking.

OBJECTIVE: This study aimed to investigate the effectiveness of workplace active rest programme (WARP) on chronic low back pain (LBP) among office workers. DESIGN: A closed cohort, stepped-wedge cluster randomised trial was conducted. The total duration of the study was 16 weeks (4 weeks for each step). Sequence allocation was randomised, but no one was blinded. SETTING: This study was conducted in three offices in a Japanese electronics company. One office was for the administrative department, the others are for the engineering department. PARTICIPANTS: We recruited 29 office workers with LBP greater than 3 months. LBP due to specific injury or disease was excluded. The median age was 38 years, and 26 (90%) were male. All participants completed the study. INTERVENTIONS: In the intervention phase, participants performed WARP comprising frequent stand-up and individualised brief exercise/physical activity during work. Physical therapists held an LBP workshop and developed tailor-made programmes before introducing WARP. We instructed participants to perform WARP at five timings during work. Control phase was set before the intervention and participants stayed as usual. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was pain intensity of LBP assessed using the Brief Pain Inventory. The secondary outcomes were work productivity loss measured using the Work Limitations Questionnaire, LBP disability assessed using the Roland-Morris Disability Questionnaire, psychosocial subscale assessed using the STarT Back Screening Tool and physical activity measured using triaxial accelerometers. These outcomes were collected at baseline and at 4-month follow-up evaluation. RESULTS: In the intention-to-treat analysis, WARP did not show any significant effects on pain intensity (ß, 0.01; 95% CI -0.50 to 0.52) and on the secondary outcomes. The median adherence to WARP was 28.6% (IQR, 16.8-41.1), which was equal to 1.43 times per day. No adverse effect was observed. CONCLUSIONS: The present study was unable to confirm the effectiveness of active rest in improving LBP. Hence, further study needs to investigate its effectiveness. TRIAL REGISTRATION NUMBER: UMIN000033210.

OBJECTIVES: Our study aimed to investigate the association between comprehensive workstations and neck and upper-limb pain (NUP) among office workers. METHODS: This cross-sectional study included 307 office workers (median age, 39 years; 88% men). Workstations (presence of armrest, armrest position, number of monitors used, mouse position, mouse usage, keyboard usage, and keyboard position) were investigated in terms of 17 items and judged as "adequate" or "inadequate." NUP was assessed using a numerical rating scale. NUP locations included the neck, shoulder, elbow, and wrist. In the statistical analysis, outcome variables were the presence of pain in each part, while explanatory variables were the number of inadequate workstations. Logistic regression analyses were conducted with adjustment for age, gender, working duration, and exercise habit. RESULTS: The prevalence of neck pain was 47% (n = 143), shoulder pain was 50% (n = 153), elbow pain was 7.2% (n = 22), and wrist pain was 13% (n = 40). In the adjusted model, the number of inadequate workstations had significant positive associations with elbow pain (odds ratio [OR], 1.39; 95% confidence interval [CI], 1.06.1.81) and wrist pain (OR, 1.80; 95% CI, 1.17.2.26). However, the number of inadequate workstations was not significantly associated with neck pain or shoulder pain. CONCLUSIONS: Workstation-related factors (presence of armrest, armrest position, mouse usage, and keyboard usage) were significantly associated with elbow and wrist pain. Our findings suggest that workstations can contribute to elbow and wrist pain in office workers.

BACKGROUND: Depressive symptoms cannot be ignored when exercise intervention is performed. The purpose of this study was to clarify the association between depressive symptoms and exercise capacity in community-dwelling older adults. METHODS: In this cross-sectional study, we analyzed 110 community-dwelling older adults (mean age [standard deviation] = 70.7 [4.0] years old; women: 55 %). Depressive symptoms were measured using a Japanese version of the Geriatric Depression Scale. We evaluated exercise capacity by measuring distance (2MWD) during a 2-minute walk test. Linear regression models were applied to analyze the association between 2MWD and depressive symptoms. RESULTS: The results suggest that depressive symptoms are associated with low 2MWD (beta = -5.87, 95 % confidence interval = -11.18 to -0.57, p < 0.05) even after adjusting for age, gender, Body Mass Index, cigarette smoking, alcohol consumption, pain severity, and the number of comorbidities. CONCLUSIONS: The results indicated that depressive symptoms are associated with decreased exercise capacity in older adults.

OBJECTIVES: The purpose of this cross-sectional study was to investigate the association between daily physical activity and sonographically measured bone status among women during the lactation period. METHODS: Final participants were 152 women 4 months after childbirth. Bone status of the participants was measured using quantitative ultrasonometry of the calcaneus (speed of sound). Daily physical activity was assessed using the Japanese version of International Physical Activity Questionnaire short version. After getting the International Physical Activity Questionnaire results, we classified participants into three categories (low/moderate/high) according to a protocol. Participants categorized into the low group according to the International Physical Activity Questionnaire were considered to be in the low physical activity group and those categorized into the moderate and high groups were considered to be in the moderate to vigorous physical activity group. RESULTS: Speed of sound was significantly higher in the moderate to vigorous physical activity group (moderate to vigorous physical activity versus low physical activity, 1533 m/s versus 1523 m/s, p = 0.03). Daily physical activity was significantly associated with speed of sound, even after adjustment for confounding factors and prognosticators (ß = 0.195, p = 0.02). CONCLUSION: Sonographically measured bone status was significantly higher in women who were physically active than in those who were physically inactive, suggesting that daily physical activity might help to maintain good bone status.

STUDY DESIGN: Retrospective study. OBJECTIVE: To investigate the association between gestational weight gain (GWG) during pregnancy and persistent low back and pelvic pain (LBPP) after delivery. SUMMARY OF BACKGROUND DATA: Persistent LBPP after delivery is a risk factor for developing depression and chronic pain as well as incurring sick leave. Women experience weight gain during pregnancy. Excessive weight gain places a greater burden on the musculoskeletal system. However, little is known about how GWG is associated with LBPP after delivery. METHODS: After Ethics Committee approval, we analyzed 330 women at 4 months after delivery who had LBPP during pregnancy. The exclusion criteria were as follows: specific low back pain, multiple birth, and incomplete data. Four months after delivery, LBPP was assessed using a self-report questionnaire. Persistent LBPP was defined as pain at 4 months after delivery with an onset during pregnancy or within 3 weeks after delivery. GWG was calculated as the difference between the pregnancy weight and the prepregnancy weight, which we categorized into three groups: <10, 10 to <15, and ≥15âkg. Other confounding factors including age, height, weight at 4 months after delivery, parity, gestational week, mode of delivery, weight of the fetus, and prepregnancy LBPP were assessed. We used logistic regression analysis to calculate LBPP odds ratios (ORs) according to GWG. RESULTS: The prevalence of persistent LBPP was 34.1% (nâ=â113). Compared with women with a GWG of <10âkg, women with a GWG of ≥15âkg had a higher prevalence of persistent LBPP (ORâ=â2.77, 95% confidence interval (95% CI)â=â1.28-5.96, adjusted ORâ=â2.35, 95% CIâ=â1.06-5.21); however, no significant difference was found for women with a GWG of 10 to <15âkg (ORâ=â1.18, 95% CIâ=â0.72-1.92, adjusted ORâ=â1.02, 95% CIâ=â0.61-1.72). CONCLUSIONS: Our study showed that excessive weight gain during pregnancy is one of the risk factors of persistent LBPP. Appropriate weight control during pregnancy could help prevent persistent LBPP after delivery. LEVEL OF EVIDENCE: 3.

This study investigated the relationship of a gap between the intent to be physically active and actual participation in physical activity ('intention-behavior gap') and self-efficacy for physical activity during childhood. A self-report questionnaire was used to collect information from 946 children from the fourth and sixth grades in Japan on self-efficacy, intention, and physical activity. Children with an intention-behavior gap (high intent-low activity or low intent-high activity) had higher self-efficacy scores than those with low intent and low activity (27.66 or 27.65 vs. 21.69; p < .001). They had lower self-efficacy scores than those with high intent and high activity (27.66 or 27.65 vs. 30.56; p < .001). Children with an intention-behavior gap had lower self-efficacy for physical activity than those who intended to be and were physically active. Such children may benefit from education interventions that focus on improving self-efficacy.

This study clarified the prevalence of daytime sleepiness in fourth-, fifth-, and sixth-grade children and examined the association between physical activity (PA) and daytime sleepiness in children aged 9-12 years. This cross-sectional study included 314 children (mean age ± standard deviation: 10.5 ± 1.0 years; male: 52.9%) enrolled in two public elementary schools in Kobe, Japan. PA was assessed using the Physical Activity Questionnaire for Older Children. The outcome was self-reported daytime sleepiness. The prevalence of daytime sleepiness in fourth-, fifth-, and sixth-grade children were 10.8%, 25.2%, and 28.6%, respectively. In univariate analysis, subjects with reported daytime sleepiness had lower PA levels than those without daytime sleepiness (odds ratio (OR) = .67; 95% confidence interval (CI) = .47-.95). Multiple logistic regression analysis demonstrated that lower PA was significantly associated with daytime sleepiness after adjusting for multiple confounders (OR = .54; 95% CI = .37-.81). The prevalence of daytime sleepiness in fifth and sixth grades was higher than fourth grade. Furthermore, this study clarified the significant association between PA and daytime sleepiness and suggested that PA could be one of the factors to prevent daytime sleepiness in children aged 9-12 years.

OBJECTIVES: This study aimed to examine the reliability and validity of the Japanese version of the Physical Activity Questionnaire for Older Children (PAQ-C) in Japanese children aged 9 to 12 years. METHODS: A total of 210 children aged between 9 and 12 years participated. Internal consistency and test-retest reliability were evaluated using Cronbach alpha coefficient and intraclass correlation coefficient (ICC), respectively. Validity was evaluated using athletic competence (AC), self-efficacy (SE), body mass index (BMI), body fat percentage (%BF), cardiovascular fitness (CVF), and World Health Organization Health Behavior in School-aged Children (WHO HBSC) physical activity questionnaire. RESULTS: Internal consistency was acceptable (alpha = 0.80) and test-retest reliability showed excellent agreement (ICC = 0.83). The PAQ-C score was significantly correlated with AC (r = 0.41), SE (r = 0.65), %BF (r = 0.19), and CVF (r = -0.32). The PAQ-C score of the active group classified by the WHO HBSC physical activity questionnaire (mean score ± standard deviation [SD] = 3.03 ± 0.57) was significantly higher than that of the inactive group (mean score ± SD = 2.27 ± 0.63, P < .01). CONCLUSIONS: The PAQ-C had acceptable reliability and validity. The PAQ-C is a useful instrument to evaluate physical activity for Japanese children aged 9 to 12 years.
RESUMO
Aim: To examine the association between public transportation use and loneliness in urban elderly who stop driving. Methods: In this cross-sectional study, we assessed 31 community-dwelling older adults who had stopped driving. Public transportation use was assessed by using frequency and divided into two groups. The users group was participants who used public transportation more than once a week and the nonusers group was participants who used public transportation less than once a week. Loneliness was measured using the Japanese version of the UCLA Loneliness Scale version 3 (UCLA.LS.ver3), with a higher score indicating greater loneliness. The independent t test was used to compare the UCLA.LS.ver3 scores between users and nonusers group. A multiple linear regression model was used with the UCLA.LS.ver3 score as the objective variable and public transportation use as the explanatory variable. Results: The UCLA.LS.ver3 score was significantly higher in the nonusers group than in the users group (nonusers group: 12.7 ± 1.9; users group: 10.1 ± 2.9, p = .017). After adjustments, public transportation use was significantly associated with lower loneliness (ß = -2.55, p = .029). Conclusion: Public transportation use might have important role to prevent loneliness in older adults who stop driving.
RESUMO
Objective: The purpose of this study was to explore the reciprocal relationship between pain severity and executive function in community-dwelling older adults. Method: In this prospective cohort study, 64 Japanese community-dwelling older adults aged 60 years or older (mean age 72.8 years; women, 68.8%) were analyzed. Pain severity was assessed by self-reported questionnaire while executive function was assessed by the Trail Making Test at baseline and at 1-year follow-up assessment. A mixed effect model was conducted to analyze the effect of baseline executive function on change in pain severity and effect of baseline pain severity on change in executive function. Results: The effect of baseline Trail Making Test on change in pain severity was not significant. On the contrary, the effect of high baseline pain severity on the decline in set shifting (Trail Making Test Part B) was significant even after adjustment with age, sex, years of education, depressive symptoms, and analgesic drug use. Conclusion: Higher baseline pain severity was associated with greater executive function decline in community-dwelling older adults. Executive function decline due to severe pain should be considered as well as pain itself.
RESUMO
OBJECTIVE: This study aimed to examine the association between joint stiffness and health-related quality of life (HRQOL) in community-dwelling older adults. METHODS: Participants in this cross-sectional study were 530 Japanese community-dwelling older adults (mean age, 73.9 years; women, 64.3%). Joint stiffness was assessed at the neck, low back, shoulder, elbow, hand or wrist, hip, knee, and ankle or feet; the duration of joint stiffness was also evaluated. We assessed HRQOL using the Short Form-12 (SF-12) and EuroQOL-5 Dimension (EQ-5D) questionnaires. We calculated the physical component summary scores (PCS) and mental component summary scores (MCS) from SF-12 and the EQ-5D index from EQ-5D. RESULTS: The prevalence of joint stiffness was 54.0%. Joint stiffness at two or more sites and at each site had a meaningful impact on PCS. Joint stiffness that lasted for 30min or more was meaningfully associated with low PCS and EQ-5D scores (PCS, 30-60min: beta=-6.122, P<0.05; >60min: beta=-5.962, P<0.01; EQ-5D index, 30-60min: beta=-0.068, P<0.01; >60min: beta=-0.070, P<0.01). Further, joint stiffness that lasted over 60min extended over MCS (MCS, >60min: beta=-3.212, P<0.05). CONCLUSIONS: Joint stiffness is associated with HRQOL. Assessing joint stiffness and intervention could be beneficial for HRQOL.
