Reliability and validity of the Japanese version of the short questionnaire to assess health-enhancing physical activity (SQUASH) scale in older adults

Physical activity and checkpoint inhibition: association with toxicity and survival

BACKGROUND

Although animal experiments suggest beneficial effects of physical activity (PA) on antitumor immunity, little is known about the effects of PA on immune checkpoint inhibitor (ICI) toxicity and effectiveness in humans. We assessed the association of PA with immune-related adverse events (irAE) and survival in patients undergoing ICI.

METHODS

Patients receiving ICI who completed the Dutch short questionnaire to assess health enhancing physical activity (SQUASH) questionnaire at the start of treatment as part of the prospective UNICIT study in an academic hospital were included. PA was quantified by calculating total metabolic equivalent task hours per week (total PA) and hours per week of moderate- to vigorous-intensity PA during sport and leisure time (MVPA-SL). Associations of PA with severe irAE occurrence within 1 year and overall survival (OS) were evaluated using logistic regression and Cox proportional hazard regression, respectively, with adjustment for probable confounders.

RESULTS

In total, 251 patients were included, with a median follow-up of 20 months. Moderate and high levels of total PA were associated with lower odds of severe irAE occurrence compared to low levels of total PA (adjusted OR: 0.34 [95% CI = 0.12 to 0.90] and 0.19 [95% CI = 0.05 to 0.55], respectively). Moderate and high levels of total PA were also associated with prolonged survival (adjusted HR: 0.58 [95% CI = 0.32 to 1.04] and 0.48 [95% CI = 0.27 to 0.89], respectively). Similar associations were observed in patients who performed more MVPA-SL.

CONCLUSIONS

Higher physical activity levels at the start of ICI treatment are associated with lower risk of severe irAEs and probably prolonged survival. Randomized controlled trials are needed to investigate whether patients indeed benefit from increasing PA levels after diagnosis.

Body mass index and waist circumference in relation to risk of recurrence and progression after non-muscle invasive bladder cancer

BACKGROUND

Obesity may be associated with increased risk of recurrence and progression in patients with non-muscle invasive bladder cancer (NMIBC), but evidence is limited and inconsistent. We examined the associations of body mass index (BMI), waist circumference, and waist-to-hip ratio (WHR) with risk of recurrence and progression among patients with NMIBC.

METHODS

This prospective study included 1029 patients diagnosed with primary NMIBC between 2014 and 2017. Patients reported weight 2 years before diagnosis at baseline, and weight, waist and hip circumference at 3 months postdiagnosis. Associations were quantified using Cox proportional hazard analyses, adjusted for clinical and lifestyle characteristics.

RESULTS

More than half of patients were overweight (49%) or obese (19%) after diagnosis. During a median follow-up time of 3.6 years, 371 patients developed ≥1 recurrence and 53 experienced progression. No associations with recurrence were observed for BMI (HRper 5 kg/m2 0.94; 95% CI 0.82, 1.07), waist circumference (HRper 10 cm 0.95; 95% CI 0.86, 1.05), or WHR (HRper 0.1 unit 0.90; 95% CI 0.76, 1.06). In contrast, higher BMI was associated with a 40% increased risk of progression, with only the 2-year prediagnosis association reaching statistical significance (HRper 5 kg/m2 1.42; 95% CI 1.09, 1.84). No associations for pre-to-postdiagnosis weight change were found.

CONCLUSION

General and abdominal obesity were not associated with recurrence risk among patients with NMIBC, but might be associated with increased risk of progression. Studies with sufficient sample size to stratify by tumor stage and treatment are needed to better understand whether and how obesity could influence prognosis.

Validation of the LPA-SQUASH in post-liver-transplant patients

AIM

This study aimed to validate the revised Short Questionnaire to Assess Health-Enhancing Physical Activity (SQUASH) to measure sedentary activity in post-liver-transplant patients. The proposed scale could be useful for transplantation nurses to assess and modify sedentary lifestyles and increase physical activity.

METHODS

The SQUASH was modified to include items on sitting time and light-intensity physical activity (LPA-SQUASH). A pilot study was conducted with 20 liver transplant patients, and an expert panel validated the scale contents. Then, post-liver-transplant outpatients at a Japanese university hospital participated in the main study (September-October 2020), in which questionnaires were mailed twice to assess test-retest reliability, and accelerometers used to establish criterion validity. Intra-class correlation coefficients (ICC) were calculated for test-retest reliability. Spearman correlations and Bland-Altman plots were used to assess validity and measurement error.

RESULTS

In total, 173 participants returned the questionnaires, and 106 and 71 completed the reliability and validation studies, respectively. The range of LPA-SQUASH correlation coefficients for test-retest was .49-.58. ICCs ranged from .72 to .80 for items other than leisure. Accelerometer data and the LPA-SQUASH total physical activity amount and light-intensity physical activity correlated moderately.

CONCLUSION

We modified the SQUASH, which was developed to measure physical activity in healthy adults, to assess light-intensity physical activity in post-liver-transplant patients. The LPA-SQUASH showed acceptable validity and reliability. The questionnaire may be used by transplantation nurses to examine light-intensity physical activity content/duration, deliver patient education considering patients' sedentary lifestyle, and facilitate goal setting for physical activity interventions to prevent metabolic syndrome.

Adherence to lifestyle recommendations after non-muscle invasive bladder cancer diagnosis and risk of recurrence

BACKGROUND

Patients with non-muscle invasive bladder cancer (NMIBC) are at a high risk of tumor recurrence. It has not been previously investigated if adherence to cancer prevention recommendations lowers the risk of recurrence.

OBJECTIVES

We examined whether the standardized lifestyle score measuring adherence to the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) cancer prevention recommendations was associated with the risk of recurrence and progression among patients with NMIBC.

METHODS

The study population included patients diagnosed with primary NMIBC between 2014 and 2017 from the prospective cohort UroLife. Lifestyle was assessed at baseline (n = 979; reflecting the prediagnosis period) and 3-mo postdiagnosis (n = 885). The standardized 2018 WCRF/AICR score was constructed based on recommendations for body weight, physical activity, diet, and alcohol intake. We computed multivariable-adjusted HRs and 95% CIs using Cox proportional hazard regression models.

RESULTS

During a median follow-up time of 3.7 y, 320 patients developed ≥1 recurrence(s) and 49 experienced progression. Patients in the highest compared with the lowest tertile of postdiagnosis WCRF/AICR scores had a lower risk of first bladder cancer recurrence (HR: 0.74; 95% CI: 0.56, 0.98). No associations were observed for multiple recurrences (HR: 0.90; 95% CI: 0.70, 1.15) or for the baseline score with either first (HR: 1.07; 95% CI: 0.82, 1.40) or multiple recurrences (HR: 1.04; 95% CI: 0.82, 1.31). Improving lifestyle after diagnosis (per 1-point increase) was not significantly associated with the risk of first or multiple recurrence(s) (HR: 0.87; 95% CI: 0.74, 1.02; HR: 0.93; 95% CI: 0.80, 1.08, respectively). No associations were observed for bladder cancer progression, but the power was limited.

CONCLUSIONS

Better adherence to the WCRF/AICR cancer prevention recommendations 3 mo after NMIBC diagnosis, but not before diagnosis, is associated with a decreased risk of first bladder cancer recurrence. More studies evaluating postdiagnosis lifestyles are needed to provide solid support for lifestyle recommendations for cancer survivors.

Adhering to the 2017 Dutch Physical Activity Guidelines: A Trend over Time 2001-2018

Recently, new physical activity (PA) guidelines were adopted in the Netherlands consisting of two components: (1) addressing duration of moderate and vigorous PA, (2) bone and muscle strengthening activities. The aim of this study is to retrospectively assess the long-term trend in fulfilling the criteria of the new PA guidelines and to gain insight into which activities contribute to changes over time. Data were available for 2001-2018 of a nationally representative sample of approximately 7000 Dutch citizens aged 12 years and over using the Short Questionnaire to Assess Health-enhancing physical activity (SQUASH). Multiple logistic regression analysis was performed by age, sex, and level of education. Overall, a positive trend was found from 39.9% adherence in 2001 to 46.0% in 2018. Adherence levels among adolescents decreased and increased among adults and seniors. Intermediate and higher educated groups showed positive trends over time whereas a stable trend was observed among lower educated. Activities contributing most to changes over time were sports, leisure time walking, and strenuous occupational activities. In the period 2001-2018, though an increasing trend was found, less than half of the population was sufficiently active. Special effort is necessary to reach adolescents, seniors, and lower educated groups in PA promotion programs.

The Reliability and Validity of the Turkish Kaiser Physical Activity Survey for Pregnant Women

BACKGROUND

Evaluation of physical activity by condition-specific surveys provides more accurate results than generic physical activity questionnaires. The aim of this study was to investigate the reliability and validity of the Kaiser Physical Activity Survey (KPAS) in Turkish pregnant women.

METHODS

In the translation and cultural adaptation of the KPAS, the 6-phase guidelines recommended in the literature were followed. The study included a total of 151 pregnant women who were assessed using the Turkish version of KPAS, the Pregnancy Physical Activity Questionnaire, and the SenseWear Pro3 Armband. To determine the test-retest reliability, the KPAS was reapplied after 7 days. The psychometric properties of KPAS were analyzed with respect to internal consistency, test-retest reliability, and concurrent validity.

RESULTS

Cronbach α coefficient indicating the internal consistency of the Turkish KPAS was found to be .60 to .80, showing moderate reliability. The intraclass correlation coefficient for test-retest reliability was very strong (intraclass correlation coefficient: .96-.98). The total KPAS scores were found to be moderately correlated with the total Pregnancy Physical Activity Questionnaire score and the total energy expenditure value on the SenseWear Pro3 Armband.

CONCLUSIONS

This study showed that KPAS is a valid and reliable instrument for evaluating physical activity in Turkish pregnant women in different aspects.

Protein supplementation improves lean body mass in physically active older adults: a randomized placebo-controlled trial

BACKGROUND

An inadequate protein intake may offset the muscle protein synthetic response after physical activity, reducing the possible benefits of an active lifestyle for muscle mass. We examined the effects of 12 weeks of daily protein supplementation on lean body mass, muscle strength, and physical performance in physically active older adults with a low habitual protein intake (<1.0 g/kg/day).

METHODS

A randomized double-blinded controlled trial was performed among 116 physically active older adults [age 69 (interquartile range: 67-73) years, 82% male] who were training for a 4 day walking event of 30, 40, or 50 km/day. Participants were randomly allocated to either 31 g of milk protein or iso-caloric placebo supplementation for 12 weeks. Body composition (dual-energy X-ray absorptiometry), strength (isometric leg extension and grip strength), quadriceps contractile function, and physical performance [Short Physical Performance Battery, Timed Up-and-Go test, and cardiorespiratory fitness (Åstrand-Rhyming submaximal exercise test)] were measured at baseline and after 12 weeks. We assessed vitamin D status and markers of muscle damage and renal function in blood and urine samples before and after intervention.

RESULTS

A larger increase in relative lean body mass was observed in the protein vs. placebo group (∆0.93 ± 1.22% vs. ∆0.44 ± 1.40%, P_Interaction  = 0.046). Absolute and relative fat mass decreased more in the protein group than in the placebo group (∆-0.90 ± 1.22 kg vs. ∆-0.31 ± 1.28 kg, P_Interaction  = 0.013 and ∆-0.92 ± 1.19% vs. ∆-0.39 ± 1.36%, P_Interaction  = 0.029, respectively). Strength and contractile function did not change in both groups. Gait speed, chair-rise ability, Timed Up-and-Go, and cardiorespiratory fitness improved in both groups (P < 0.001), but no between-group differences were observed. Serum urea increased in the protein group, whereas no changes were observed in the placebo group (P_Interaction  < 0.001). No between-group differences were observed for vitamin D status, muscle damage, and renal function markers.

CONCLUSIONS

In physically active older adults with relatively low habitual dietary protein consumption, an improvement in physical performance, an increase in lean body mass, and a decrease in fat mass were observed after walking exercise training. A larger increase in relative lean body mass and larger reduction in fat mass were observed in participants receiving 12 weeks of daily protein supplementation compared with controls, whereas this was not accompanied by differences in improvements between groups in muscle strength and physical performance.

The association of parental obesity with physical activity and sedentary behaviors of their children: the CASPIAN-V study

OBJECTIVE

Low physical activity and sedentary behaviors, two important determinants of childhood obesity, may be influenced by parental lifestyle and weight status. This study aims to determine the association of parental weight status with children's physical activity and screen time.

METHODS

This study was conducted on 14,440 Iranian schools students, aged 7-18 years, and one of their parents, who participated in the large national school-based surveillance program. The children's screen-based and physical activities were evaluated based on the World Health Organization's Global School Student Health Survey. Children and parental height, weight, and waist circumference were measured using standardized methods.

RESULTS

Overall, 14,274 students and one of their parents completed the survey (participation rate: 99%). Mean (standard deviation) age of students was 12.3 (3.2) years, and the prevalence of low physical activity and high screen time was 58.2% and 17.7%, respectively. In multivariate model, the parental general obesity and abdominal obesity increased the odds of children having low physical activity, by 21% and 13%, respectively. Parental overweight, general obesity, and abdominal obesity increased the odds of the combination of low physical activity/high screen time in children by 33%, 26%, and 20%, respectively.

CONCLUSIONS

This study showed that parental obesity was associated with increased screen-based activities and low physical activity in children. Focus on parental weight status, as an important factor influenced by their lifestyle, can be helpful for preventing sedentary behaviors in their children.

Protein Intake and Distribution in Relation to Physical Functioning and Quality of Life in Community-Dwelling Elderly People: Acknowledging the Role of Physical Activity

Increasing total protein intake and a spread protein intake distribution are potential strategies to attenuate sarcopenia related loss of physical function and quality of life. The aim of this cross-sectional study was to investigate whether protein intake and protein intake distribution are associated with muscle strength, physical function and quality of life in community-dwelling elderly people with a wide range of physical activity. Dietary and physical activity data were obtained from two studies (N = 140, age 81 ± 6, 64% male), with the following outcome measures: physical functioning (Short Physical Performance Battery (SPPB), comprising balance, gait speed and chair rise tests), handgrip strength and quality of life (EQ-5D-5L). Protein intake distribution was calculated for each participant as a coefficient of variance (CV = SD of grams of protein intake per main meal divided by the average total amount of proteins (grams) of the main meals). Based on the CV, participants were divided into tertiles and classified as spread, intermediate or pulse. The average total protein intake was 1.08 ± 0.29 g/kg/day. Total protein intake was not associated with outcome measures using multivariate regression analyses. Individuals with a spread protein diet during the main meals (CV < 0.43) had higher gait speed compared to those with an intermediate diet (CV 0.43⁻0.62) (β = -0.42, p = 0.035), whereas a spread and pulse protein diet were not associated with SPPB total score, chair rise, grip strength and Quality-Adjusted Life Year (QALY). The interaction of higher physical activity and higher total protein intake was significantly associated with higher quality of life (β = 0.71, p = 0.049). While this interaction was not associated with SPPB or grip strength, the association with quality of life emphasizes the need for a higher total protein intake together with an active lifestyle in the elderly.

Reliability of the Danish version of the short questionnaire to assess health-enhancing physical activity (SQUASH)

OBJECTIVE

To translate and cross-cultural adapt the short questionnaire to assess health-enhancing physical activity (SQUASH) to Danish, and to investigate the Danish version's reliability.

METHODS

The study was conducted according to the COSMIN guidelines. The reliability was evaluated in 53 healthy subjects, mean age 47.1 ± 12.4 years and mean period 37.8 ± 14.8 days between test and retest.

RESULTS

For the total activity score ICC was 0.73 (0.57 to 0.83), SEM was 2316 (24% of the grand mean), and SDC was 6419 (67% of the grand mean).

CONCLUSION

The relative reliability was acceptable and indicates that the Danish version of SQUASH can be used to distinguish between individuals; however, the absolute reliability was poor and SQUASH is not considered suitable for measuring physical activity on an individual level.

Reliability and validity of the Korean version of the Short Musculoskeletal Function Assessment questionnaire for patients with musculoskeletal disorder

[Purpose] The purpose of this study was to establish the reliability and validity of the Short Musculoskeletal Function Assessment questionnaire, which was translated into Korean, for patients with musculoskeletal disorder. [Subjects and Methods] Fifty-five subjects (26 males and 29 females) with musculoskeletal diseases participated in the study. The Short Musculoskeletal Function Assessment questionnaire focuses on a limited range of physical functions and includes a dysfunction index and a bother index. Reliability was determined using the intraclass correlation coefficient, and validity was examined by correlating short musculoskeletal function assessment scores with the 36-item Short-Form Health Survey (SF-36) score. [Results] The reliability was 0.97 for the dysfunction index and 0.94 for the bother index. Validity was established by comparison with Korean version of the SF-36. [Conclusion] This study demonstrated that the Korean version of the Short Musculoskeletal Function Assessment questionnaire is a reliable and valid instrument for the assessment of musculoskeletal disorders.

Measurement of physical activity in obese persons: how and why? A review

[Purpose] Overweight and obesity are major risk factors for poor health, especially in children. Reduced physical activity, prompted by a sedentary lifestyle, is a major contributor. Hence, it is important to assess physical activity using standardized methods in public health to identify the risks associated with obesity. There have been no recent reports comparing such modalities for use by clinicians and researchers. In this article, some of these methods for use in the assessment of physical activity are reviewed, and their advantages and disadvantages are described. [Subjects and Methods] Electronic databases including PubMed, Medline, and Google Scholar were searched for literature, using key words Obesity, Physical activity, and Physical Behavior Monitoring. [Results] With advances in technology, various novel methods have been developed to assess physical behavior, but conventional methods are still relevant and easy to administer. [Conclusion] There are various measurement options available. Researchers may choose devices providing more accurate measurements, while clinicians may prefer portability and affordability for patients.

Pregnancy physical activity questionnaire (PPAQ): reliability and validity of Turkish version

[Purpose] The aim of this study was to translate the Pregnancy Physical Activity Questionnaire into Turkish and test its reliability and validity among Turkish pregnant women. [Subjects and Methods] The subjects were 204 healthy, single pregnant women between the ages 18 and 40 who volunteered to participate in this study. Reliability was evaluated by measuring the one-week test-retest reliability with the intraclass correlation coefficient and Pearson's correlation analysis. Concurrent validity was examined by comparing the Pregnancy Physical Activity Questionnaire with the long form of the International Physical Activity Questionnaire and step counts with pedometer. [Results] The mean age of the participants was 28.23±4.94 years, and the mean for BMI was 26.09±4.40. For test-retest reliability, r values were respectively 0.961, 0.934, 0.957 and 0.981 for self-reported sedentary, light, moderate, and vigorous activity, respectively. Intraclass correlation coefficient scores ranged from 0.924 to 0.993. For validity, the Pearson's correlation coefficients between the Pregnancy Physical Activity Questionnaire and long form of the International Physical Activity Questionnaire ranged from moderate (r = 0.329) to high (r = 0.672). The correlation value between the total score of the Pregnancy Physical Activity Questionnaire and the step counts was 0.70. [Conclusion] The Turkish version of the Pregnancy Physical Activity Questionnaire is a valid and reliable tool for measurement of the physical activity level of pregnant women.

The Turkish version of the pregnancy physical activity questionnaire: cross-cultural adaptation, reliability, and validity

[Purpose] The aim of this study was to translate the Pregnancy Physical Activity Questionnaire, adapt it for use with Turkish subjects and determine its reliability and validity. [Subjects and Methods] The Pregnancy Physical Activity Questionnaire was translated into Turkish and administered twice at 7–14-day intervals to pregnant women to assess the test-retest reliability. Cronbach’s α was used for internal consistency, and the inter-rater correlation coefficient was used to calculate the test-retest reliability. The Turkish Short Form 36 Health Survey (SF-36) and the International Physical Activity Questionnaire were used to estimate validity. [Results] The internal consistency during the first and third trimesters of pregnancy was excellent, with Cronbach’s α values of 0.93 and 0.95, respectively. The mean interval between the two assessments was 11.1 ± 2.1 days. The correlation coefficient between the total activity measured by the Turkish version of the Pregnancy Physical Activity Questionnaire and the International Physical Activity Questionnaire estimates of the total metabolic equivalent were fair to poor during the first, second, and third trimesters of pregnancy (r = 0.17, r = 0.17, r = 0.21, respectively). The Turkish version of the Pregnancy Physical Activity Questionnaire showed fair correlations with the Short Form 36 Health Survey physical component score (r = −0.30) and mental component score (r = −0.37) for the first trimester of pregnancy. [Conclusion] The Turkish version of the Pregnancy Physical Activity Questionnaire was found to be reliable and valid for assessing a pregnant woman’s physical activity.

Effects of sitting time associated with media consumption on physical activity patterns and daily energy expenditure of Saudi school students

[Purpose] This study was performed to assess the effect of daily sitting time during media consumption on physical fitness, total energy expenditure (TEE), and body composition indices of Saudi school children. [Subjects and Methods] A total of 180 healthy Saudi school students (8-18 years) were included in this study. Sitting time, total energy expenditure, and levels of physical activity were evaluated with pre-validated internet based questionnaires. Body composition indices were evaluated using anthropometric analysis. [Results] Out of the studied participants, only 22.2% of students were physically inactive. Children with moderate and active physical scores demonstrated less sedentary behavior (TV viewing and computer usage), lower body composition values (BMI, WC, WHtR), and higher TEE than sedentary or mild activity level participants. Boys showed higher fitness scores and less sedentary behavior than girls. Media sitting time among the studied subjects correlated negatively with physical scores and positively with body composition. [Conclusion] The data presented here suggests that poor physical fitness, lower TEE, and longer sitting times differentially influence normal body composition indices among school children which may lead to overweight or obese individuals. Thus, decreasing sitting time during media consumption and enhancing physical activity may play a pivotal role in preventing obesity in young children.

Physical activity and environmental influences on adrenal fatigue of Saudi adults: biochemical analysis and questionnaire survey

[Purpose] This research work was performed to examine whether different levels of physical activity and environmental and social factors are associated with changes in adrenal hormones as markers of adrenal fatigue in Saudi adult volunteers. [Subjects and Methods] A total of 160 Saudi adults aged 15-22 years were included in this study. The adrenal fatigue score, sociodemographic attributes, and the level of physical activity were evaluated via pre-validated internet-based questionnaire surveys. Adrenal hormones such as ACTH and cortisol were measured using immunoassay techniques. [Results] Significant increases in the levels of ACTH and cortisol biomarkers were found in the participants with moderate to severe fatigue scores, poor environmental factors, and low physical activity. However, in physically active participants, significant decreases in ACTH and cortisol levels were found with remarkable improvement in adrenal fatigue status. The decrement in adrenal hormonal levels positively correlated (r= 0.976) with the improvement in adrenal fatigue status in the physically active participants. [Conclusion] Our results suggest that the level of physical activity and environmental and social factors differentially influence the adrenal fatigue status via changes in the levels of adrenal hormones. Also, ACTH and cortisol biomarkers may be useful as markers measuring the severity of adrenal fatigue.
