Association between occupational physical activity and quantitative bone ultrasound in sawmill workers

A small number of studies have examined the relationship between bone health and level of physical load. We explored the effect of occupational physical activity on skeletal status in younger sawmill workers using ultrasonic indices of bone density. In a cross-sectional study, we measured bone density with quantitative ultrasound (QUS) in 128 sawmill workers (89 men and 39 women), mean age 39.1 +/- 10.8 years. Back strength was measured by dynamometry. Information on occupational and leisure physical activity, joint pain, education and smoking were obtained with the questionnaire. All QUS bone parameters and back strength were significantly higher in men than in women. A T score for quantitative ultrasound index (QUI) of − 2.2 or lower was found only in two men and one women. QUI did not significantly differ based on presence of parameters of physical occupational activity (carrying loads exceeding 5 kg, repetitive movements, physical exertion while working and non-sitting position at work). When controlling for age, gender and body mass index, participants with higher smoking index had significantly lower QUI (p=0.004). Physical workload was not significantly associated with QUI. In our working population, some lifestyle habits, such as smoking, had a greater impact on bone health than physical occupational activity.

BackgroundEmerging evidence, predominately from European and Asian countries, describes opposing effects of occupational physical activity (OPA) and leisure-time physical activity (LTPA) on cardiovascular health. This analysis examined cardiovascular disease (CVD) prevalence associated with OPA and LTPA.MethodsThis cross-sectional analysis of 2015 National Health Interview Survey data (n=16 974) employed logistic regression to estimate odds (OR) of self-reported CVD (coronary heart disease, heart attack, stroke or angina) with self-reported total occupational activity (TOA), occupational exertion (OE), occupational standing and walking (OSW) and LTPA. OPA was measured using two questions: ‘How often does your job involve…’ (1) ‘repeated lifting, pushing, pulling or bending?’ (OE) and (2) ‘standing or walking around?’ (OSW) with responses on a 5-item Likert scale (0=never, 4=always). TOA was categorised similarly after summing OE and OSW scores. LTPA was defined as 0, 1–149 or ≥150 min/week of moderate-to-vigorous activity. All models adjusted for common socioeconomic variables and additional analyses were stratified by sex, smoking status and LTPA.ResultsOdds for CVD were higher when ‘always’ performing TOA (OR 1.99 95% CI 1.12 to 3.53), OE (OR 2.15, 95% CI 1.45 to 3.19) or OSW (OR 1.84, 95% CI 1.07 to 3.17) compared with ‘never’. When restricting to never-smokers, odds for CVD were higher when ‘always’ performing TOA (OR 3.00, 95% CI 1.38 to 6.51) and OE (OR 3.00, 95% CI 1.80 to 5.02) versus ‘never’.ConclusionAssociations of high OPA with CVD were equally apparent across sexes, stronger in lower LTPA levels and stronger in never-smokers. While uncontrolled confounding is still possible, even after extensive adjustment, the seemingly paradoxical adverse associations with OPA and CVD should be investigated further.

Osteoporosis is a global health problem with increasing importance. It is a chronic, debilitating disease characterized by low bone density and deterioration of the micro architectonics of bone tissue. Although genetic factors largely determine the bone size and density, factors such as healthy eating, good physical activity and avoiding alcohol and smoking also play a key role. At all ages, healthy eating is an important factor in bone health. Aim: To study the eating habits that are important for bone health in women from Varna. Methods: A cross-sectional study of the eating habits of 139 women in Varna was conducted between January 2018 and March 2019. Questions, giving information on diet, frequency of consumption of certain food groups and beverages, affecting bone density, physical activity, demographic indicators are included in the questionnaire. Descriptive analysis of the data is done with SPSS version 19. Results: The average age of the participants was 29.86 ± 13.60 years. Daily consumption of milk and dairy products was found among 36.7% and 32.4% of the respondents respectively. The relative share of respondents who consume fish 1-2 times a week is 33.1%. The daily consumption of fruits and vegetables is 47.5% and 56.8% respectively. Conclusion: Nutrition plays an important role in reducing the risk of osteoporosis by affecting the development and maintenance of bone mass.

AbstractObjectiveFew data exist looking at vitamin D status and bone health in school-aged boys and girls from Saudi Arabia. The present study aimed to determine the extent of poor vitamin D status in school boys and girls aged 6–18 years and to examine if there was any difference in status with age, physical activity and veiling and concomitant effects on bone.DesignCross-sectional study.SettingJeddah, Kingdom of Saudi Arabia.SubjectsA total of 150 boys (7–16 years) and 150 girls (6–18 years) from local schools were divided into age categories: 6–9 years (elementary school); 10–12 years (secondary school); 13–14 years (middle years); 15–18 years (high school).ResultsVitamin D status was significantly lower in girls than boys in all age groups (P < 0·01), with the 15–18-year-old girls having the lowest level (22·0 (sd 9·4) nmol/l) in comparison to the 15–18-year-old boys (39·3 (sd 14·0) nmol/l) and the 6–9-year-old girls (41·2 (sd 9·3) nmol/l). Parathyroid hormone status was highest in the 15–18-year-old girls in comparison to boys of the same age. A total of 64 % of 15–18-year-old girls had 25-hydroxyvitamin D (25OHD) status <25 nmol/l in comparison to 31 % in the 13–14 years age category, 26 % in the 10–12 years category and 2·5 % in the 6–9 years category. No boys had 25OHD status <25 nmol/l. Fully veiled girls had lower 25OHD status than partly veiled or unveiled girls (P < 0·05). Low 25OHD and high parathyroid hormone was associated with lower bone mass in the 6–9 years and 13–14 years age groups (P < 0·05).ConclusionsThese data suggest significant hypovitaminosis D in older adolescent females, which is a cause for concern given that there is currently no public health policy for vitamin D in the Kingdom of Saudi Arabia.

ObjectivesTo examine patterns of sedentary behaviour and physical activity, among Japanese workers with differing occupational activity types.DesignA cross-sectional observational study in 2013–2015.SettingTwo local communities in Japan.ParticipantsFull-time workers aged 40–64 years (n=345; 55% men) and who lived in two cities.Main outcome measuresFrom accelerometer data for 7 days, mean overall sedentary time, prolonged bouts of sedentary time and light-and moderate-to vigorous-intensity of physical activity (LPA and MVPA) as a proportion of accelerometer wear time and number of breaks per sedentary hour were identified for four time periods: working hours, workdays, non-work hours and non-workdays. These sedentary behaviour and physical activity measures in the four time periods were examined among workers with four self-attributed occupational activity types (mainly sitting, standing, walking, and physical labour), adjusting for sociodemographic attributes. Diurnal patterns of sedentary behaviour, LPA, and MVPA were examined.ResultsIn working hours, those with a sitting job had significantly more total and prolonged sedentary time (total: p<0.001; prolonged: p<0.01) along with less LPA (p<0.001) and MVPA (p<0.001) and less frequent breaks (p<0.01), compared with those with the three more active job type. Similar differences by job type were found for the whole working day, but not for prolonged sedentary time and breaks. On non-working hours and days, differences in sedentary and physically active patterns by job type were not apparent.ConclusionsOccupational activity type is related to overall sedentary time and patterns on working days, but not to leisure-time sitting and activity patterns, which were similar across the sitting, standing, walking, and physical labour occupational activity types.

ObjectivesThis study aimed to investigate associations between occupational physical activity patterns (physical work demands linked to job title) and leisure time physical activity (assessed by questionnaire) with cardiorespiratory fitness (assessed by exercise test) among men and women in the German working population.DesignPopulation-based cross-sectional study.SettingTwo-stage cluster-randomised general population sample selected from population registries of 180 nationally distributed sample points. Information was collected from 2008 to 2011.Participants1296 women and 1199 men aged 18–64 from the resident working population.Outcome measureEstimated low maximal oxygen consumption (V˙O2max), defined as first and second sex-specific quintile, assessed by a standardised, submaximal cycle ergometer test.ResultsLow estimatedV˙O2maxwas strongly linked to low leisure time physical activity, but not occupational physical activity. The association of domain-specific physical activity patterns with lowV˙O2maxvaried by sex: women doing no leisure time physical activity with high occupational physical activity levels were more likely to have lowV˙O2max(OR 6.54; 95% CI 2.98 to 14.3) compared with women with ≥2 hours of leisure time physical activity and high occupational physical activity. Men with no leisure time physical activity and low occupational physical activity had the highest odds of lowV˙O2max(OR 4.37; 95% CI 2.02 to 9.47).ConclusionThere was a strong association between patterns of leisure time and occupational physical activity and cardiorespiratory fitness within the adult working population in Germany. Women doing no leisure time physical activity were likely to have poor cardiorespiratory fitness, especially if they worked in physically demanding jobs. However, further investigation is needed to understand the relationships between activity and fitness in different domains. Current guidelines do not distinguish between activity during work and leisure time, so specifying leisure time recommendations by occupational physical activity level should be considered.

The Relationship

Bone is influenced by physical activity (PA) throughout life, but childhood and adolescence provide a key opportunity to maximize peak bone mass. Thus, it is important to identify the relationship between PA practiced in childhood and young adulthood to design a promotion plan for bone health. The purpose of this study was to analyze the relationship between different impact-loading PAs (and their continuity throughout school periods from childhood to young adulthood) and bone stiffness index (SI). In this cross-sectional study, which was conducted on 145 university students aged 18–21 years, bone measurements were measured by quantitative ultrasonometry (QUS), and PA information was recalled using a self-administered questionnaire. Associations between the SI and the impact of PA performed during secondary school (p = 0.027), high school (p = 0.002), and university (p = 0.016) periods were observed. The continuity of PA over a longer period of time was related to a higher SI (p = 0.007). Those who practiced PA throughout all school periods had a higher SI than those who practiced during primary school only (p = 0.038) or through primary and secondary schools (p = 0.009). These results suggest that impact-loading PA practiced during different school periods is related to higher values of the SI. Therefore, continuous PA from an early age may be an important contributing factor to achieving and maintaining adequate bone health.
