The bidirectional association between chronic musculoskeletal pain and sleep-related problems: a systematic review and meta-analysis.

OBJECTIVES: This systematic review and meta-analysis synthesizes the evidence on prospective bidirectional associations between sleep-related problems (SRP) and chronic musculoskeletal pain (CMP). METHODS: A literature search for cohort studies available in the PubMed, Scopus, Web of Science, PsycINFO and Cochrane Library databases as of 19 July 2022 was performed. Pooled odds ratios and effect sizes were calculated through random effects meta-analysis. Subgroup and meta-regression analyses were performed to explore differences by follow-up time, proportion of each sex and mean age. The Meta-analysis Of Observational Studies in Epidemiology guidelines were strictly followed. RESULTS: Twenty studies with a total of 208 190 adults (aged 34.4-71.7 years) were included, with 17 of them being used in the meta-analysis. Individuals with SRP at baseline had a 1.79-fold higher incidence (odds ratio [OR] = 1.79; 95% CI: 1.55, 2.08; I2 = 84.7%; P < 0.001) and a 2.04-fold higher persistence (OR = 2.04; 95% CI: 1.42, 2.94; I2 = 88.5%; P < 0.005) of CMP than those without SRP. In the subgroup analysis of the association between SRP and CMP, the longer the follow-up time of the studies, the higher the heterogeneity between them. In the corresponding meta-regression, no significant effect was observed for follow-up time, sex proportion or age. Individuals with CMP at baseline had a 2.02-fold higher incidence of SRP (OR = 2.02; 95% CI: 1.62, 2.53; I2 = 90.0%; P < 0.001) than those without CMP. CONCLUSION: This study provides robust evidence concerning the longitudinal association between SRP and incidence-persistence of CMP in adults. In addition, the available prospective studies support the existence of a bidirectional relationship between CMP and SRP. PROSPERO REGISTRATION NUMBER: CRD42020212360.

Burnout and Long-term Sickness Absence From the Teaching Function: A Cohort Study.

Background: The present objective was to verify whether burnout (emotional exhaustion [EE], depersonalization [DP] and low professional efficacy [PE]) is a risk factor for long-term sickness absence (LTSA; ≥30 consecutive days) from the teaching role. Methods: This was a prospective cohort study with two years of follow-up that investigated 509 elementary and high-school teachers. Burnout was identified by Maslach Burnout Inventory. Poisson regression with robust variance was used to adjust for possible confounders. Results: The incidence of LTSA was 9.4%. High EE levels were associated with LTSA in the crude analysis, but the association lost statistical significance after adjustments (for sex, age, perception of work-life balance, general self-rated health, chronic pain and depression). High DP levels were associated with this outcome, even after all adjustments (relative risk = 1.80; 95% confidence interval: 1.05-3.09). Low PE levels were not related to LTSA. Conclusion: The results reinforce the need to improve teachers' work conditions to reduce burnout, particularly DP, and its consequences.

Gender Analyses of Brazilian Parental Eating and Activity With Their Adolescents' Eating Habits.

OBJECTIVE: To explore the associations between the eating habits of sons and daughters and the eating habits, sedentary behavior, and physical activity of their fathers and mothers. DESIGN: A cross-sectional survey of adolescents. SETTING: The 6 largest schools in Londrina, Brazil. PARTICIPANTS: A total of 842 adolescents, 842 mothers, and 842 fathers participated in this study. MAIN OUTCOMES MEASURES: Eating habits of adolescents and sedentary behavior, physical activity, and eating habits of their fathers and mothers, measured by questionnaire. ANALYSIS: The associations were identified by binary logistic regression, adjusted by adolescent's age, family's socioeconomic status, parents' educational level, and the other parental behavior. RESULTS: Independent of educational level and socioeconomic condition, mothers' eating behaviors seem to be more closely related to their adolescent children's eating behavior (vegetables, fruits, fried foods, soft drinks, and sweets [P = .001]) than fathers' behaviors (fried foods and sweets [P = .01], soft drinks [P = .001]). In addition, the behaviors of mothers were more associated to the behaviors of daughters than to the behaviors of sons (7 vs 5 associated behaviors), while behaviors of fathers were more associated with the behaviors of sons than to the behaviors of daughters (4 vs 2 associated behaviors). No associations were noted for sedentary and physical activity behavior and eating behaviors between adolescents and their parents. CONCLUSIONS AND IMPLICATIONS: Many eating habits of adolescents were associated with eating habits of both fathers and mothers, emphasizing the importance of family-focused health promotion actions. Future research is needed incorporating into the analyses, among others, the nutritional statuses and the clustering of healthy and unhealthy behaviors of parents and their children.

Association between hypertension in adolescents and the health risk factors of their parents: an epidemiological family study.

Hypertension in adolescence may be a predictor of cardiovascular problems in adulthood. Therefore, verification of the factors associated with this condition in adolescence is important. The aim of this study was to analyze the relationship between hypertension in adolescents with hypertension and the sociodemographic characteristics and lifestyle of their parents. This study was conducted on 1231 adolescents, 1202 mothers, and 871 fathers. The blood pressure of the adolescents was measured with an oscillometric device. Details of parental hypertension, sociodemographic characteristics, and lifestyle were obtained by self-report. The prevalence of hypertension was higher among adolescents with older fathers and older mothers, with both parents reporting hypertension and with mothers who were overweight. In multivariable analysis, adolescents with older mothers (OR = 2.36; 95% confidence interval [CI] = 1.12-4.98), hypertensive mothers (OR = 2.22 [95% CI = 1.26-3.89]), and hypertensive fathers (OR = 1.70 [95% CI = 1.03-2.81]) were more likely to have hypertension. In the analysis that considered clusters of health risk factors, higher risks of hypertension were observed in adolescents whose mothers had four or more aggregated risk factors (OR = 2.53 [95% CI = 1.11-5.74]). In conclusion, there was a relationship between hypertension in adolescents and hypertension in their parents. However, an association between hypertension in adolescents and parental age and clusters of health risk factors was only observed for their mothers.

Association Between Chronic Pain and Leisure Time Physical Activity and Sedentary Behavior in Schoolteachers.

Chronic pain (CP) is a public health problem with harmful social and individual effects, and its relationships with physical activity (PA) and sedentary behaviors are unclear. This study examined the relationship between CP and PA and time spent watching television as an indicator of leisure time sedentary behavior, and explored the effects of major confounding factors. The information was obtained between 2012 and 2013 from individual interviews with 943 teachers from public schools in Londrina, Brazil. Statistical analysis was performed in 2014 using a logistic regression model adjusted for sociodemographic, lifestyle, depression, and working conditions variables. The prevalence of CP was 31.9%. No statistically significant association was observed between PA and CP. In the adjusted analyses, CP was associated with time > 60 minutes/day spent watching television (odds ratio [OR] = 1.39, 95% confidence interval [CI] 1.03, 1.89) on weekdays. In analyses stratified according to body areas affected by CP, only pain in the lower limbs was associated with more time watching television (OR = 1.62, 95% CI 1.06, 2.47). Watching television on a weekday for > 60 minutes is a sedentary behavior associated with a greater likelihood of teachers having chronic pain, especially in the lower limbs. This association was observed independently of the main confounders such as sex, age, leisure time physical activity, depression and working conditions.
