Musculoskeletal pain is common in children but studies on the outcome and predictive factors for persistence/recurrence of these symptoms are scarce. A baseline cross-sectional survey of 1,756 schoolchildren (mean age 10.8) identified 564 (32.1%) children with musculoskeletal pain. At baseline, these children were evaluated using a structured questionnaire(More)
BACKGROUND Chronic abdominal pain (CAP) is common among schoolchildren, but risk factors for its onset are still largely unknown. AIMS To determine the frequency of onset of CAP in schoolchildren and investigate risk factors for its development. METHODS 1411 schoolchildren aged 11-14 years were recruited from schools in North West England. Information(More)
OBJECTIVE To determine the short-term and long-term prognosis of preadolescent lower limb pain and to assess factors that contribute to pain persistence at 1-year follow-up and pain recurrence at 4-year follow-up. METHODS A 1- and 4-year follow-up was conducted of a population-based 10- and 12-year old cohort of schoolchildren with lower limb pain at(More)
This study investigated the natural course of neck pain (NP) in 9-12-year-olds during a 4-year follow-up. Risk factors for the occurrence and persistence of weekly NP were explored separately for boys and girls. At baseline, 1756 schoolchildren completed a questionnaire eliciting musculoskeletal pain symptoms, other physical, and psychological symptoms and(More)
OBJECTIVES To review the oral cancer (OC) studies that were conducted in Arab countries with regard to epidemiology, risk factors, and prognosis. METHODS A computer-based PubMed literature search was performed to retrieve studies conducted in the Arab world on epidemiology of OC. After screening for exclusion criteria, cross-referencing, and searching(More)
Little is known about the epidemiology of widespread pain (WSP) in children and adolescents. This study aims to estimate the new-onset and prognosis of WSP in schoolchildren and investigate factors predicting its development. A prospective study was conducted among 1756 schoolchildren (age 10-12 years) in Southern Finland. At baseline, information was(More)
BACKGROUND The child's lower limb is the most commonly reported musculoskeletal location with pain and also the most commonly injured site in sports. Some potential risk factors have been studied, but the results are inconsistent. We hypothesized that distinction of traumatic from non-traumatic pain would provide a clearer picture of these factors. The aim(More)
BACKGROUND Musculoskeletal pain symptoms are common in children and adolescents. These symptoms have a negative impact on children's physical and emotional well-being, but their underlying aetiology and risk factors are still poorly understood. Most of the previous cohort studies were conducted among mid and/or late adolescents and were mainly focused on a(More)
OBJECTIVE To assess the epidemiology of attention deficit hyperactivity disorder (ADHD) in Arab countries, and identify gaps for future research. METHODS We searched PubMed from July 1978 to July 2014 and reviewed local journals with cross-referencing. The keywords we used were ADHD, diagnosis, prevalence, incidence, factor, diagnosis, rate, risk, and(More)
Aggregation of low back symptoms in families of children with low back pain (LBP) has been described. However, this may be due to genetic factors or common exposure to environmental factors. The aim of this study was to evaluate the relative contribution of genetic and environmental factors to childhood LBP by comparing the pairwise similarity of LBP in(More)
