Trabalho remoto e dores nas costas durante a pandemia da COVID-19 em adultos e idosos no Sul do Brasil

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

O objetivo deste artigo é investigar a associação entre trabalho remoto e dores nas costas durante a pandemia da COVID-19 e analisar essa relação segundo o índice de massa corporal. Estudo transversal de base populacional realizado em duas cidades no sul do Brasil em indivíduos acima de 18 anos. Dados foram coletados por meio de entrevistas domiciliares entre outubro-janeiro de 2020-2021. Desfechos: dor nas costas (cervical, torácica, lombar/aguda, crônica) e intensidade da dor. Variável de exposição: trabalho remoto. Para as análises, foram utilizadas regressão de Poisson com ajuste robusto para variância, estratificadas pelo IMC (eutrófico vs. sobrepeso/obeso) e restritas àqueles que trabalharam no último mês. Durante a pandemia, 1.016 trabalharam, média 42 anos (DP = 14), entre 18 a 93 anos. Trabalho remoto foi realizado por 7,7% dos indivíduos. Prevalência de dor nas costas: 25.6% (IC95%:19,5 a 31,7%). Trabalhadores remotos com sobrepeso/obesidade sentiram dor aguda cervical RP = 2,82 (IC95%:1,15 a 6,92); torácica aguda RP = 1,81 (IC95%:3,76 a 8,68); lombar crônica RP = 1,85 (IC95%:1,04 a 3,29), comparados àqueles que não trabalharam. Cerca de um em cada quatro trabalhadores remotos reportou dor nas costas durante a pandemia. O IMC mostrou-se ser um importante moderador entre defechos e variável de exposição.

Intervening variables	Description
Gender	Male/female
Age (years)	Categorized by age groups: 18-39, 40-5, ≥ 60
Asset index	The economic level was analyzed using the variable “asset index”. This variable was generated from a principal component analysis, taking into account household characteristics (number of pieces in the house and number of bathrooms) and household goods (freezer, tumble dryer, air conditioning, computer, internet and car ownership). The first component was extracted, which explained about 30% of the variance of all items (eigenvalue > 2.0). Based on household characteristics and some home appliances identified in the domiciles, which were used as a socioeconomic indicator. It was categorized in terciles (from lower to higher).
Sleep quality	The following question was used to determine sleep quality: How would you evaluate your sleep quality? It was categorized as: very good, good/fair, poor, very poor
Leisure time exercise	Based on the leisure section of the International Physical Activity Questionnaire (IPAQ) and defined as individuals who are engaged in any level of physical activity during their free time.
Body mass index (BMI)	Self-reported body weight and height and categorized as underweight and normal (up to 24.9 kg/m2); overweight (25.0 a 29.9 kg/m2) and obese (≥ 30.0 kg/m2).
Health variables (hypertension, depression, heart conditions)	Determined according to the following questions: Has any doctor diagnosed you as having high blood pressure/depression/heart conditions? Responses included yes, no, do not remember/do not know. For those who responded with “no” or “do not remember/do not know” it was considered “no”, and when the response was positive, “yes”. Categorized as No/Yes.
Fear of contracting Covid	Based on the Fear of COVID-19 Scale⁴. A score was generated in quintile and the last quintile was isolated. Categorized as No/Yes
Help with household chores	The following question was used: Have you had any help with daily chores (for example: cooking meals, cleaning the house, shopping)? Answers were: no, yes and ignored. They were dichotomized considering the “ignored” and negative responses as “no”, and the others as “yes. Categorized as No/Yes.
Covid Symptoms	All reported symptoms (cough, sore throat, fever, difficulty breathing, tiredness, diarrhea, loss of taste/smell, shivering, headache) were put together. The responses were considered as “yes” for any symptom reported and “no” for negative responses. Categorized as No/Yes.
Worse health perception	The following question was made: How would you evaluate your overall health? Responses included: excellent, very good, good, fair and poor. The responses considered as excellent, very good and good were considered as “no”, and the responses considered as fair and poor were considered as “yes”. Categorized as No/Yes.
