Risk behavior in patients with severe mental disorders: a prospective study of 121,830 patients managed in rural households of western China

Table 1 Regional distribution of patients with SMD and incidence of high risk behaviors of patients in rural households of Sichuan province in cohort, from 2006 to 2013^a

^aPopulation refers to agricultural population in 2013
N₁: the number of registered patients with SMD
Register rate: the rate of registered patients with SMD in local population. Limited by variable objective conditions, registration rate is lower than the prevalence rate of SMD. Register rate = N₁/ Population
N₂: the number of high risk behavior patients in registered patients with SMD. As mentioned in 2.1.1, whether a patient is classified into a high risk group is according to the highest risk level in their follow-up period. If they were once, or more times, evaluated as L3 to L5, they were classified into a high risk group
No. of high risk behaviors: the number of occurrences for high risk behavior in registered patients with SMD. In this study, there were 115,026 patients whose no. of high risk behaviors was 0, and the remaining patients with no. of high risk behaviors ranged from 1 to 40
Follow-up person years: the sum of the years of follow-up time of registered patients with SMD
Incidence rate: the incidence rate of high risk behavior in registered patients, and the follow-ups in person years were used as the denominator to define the incidence of high risk behavior. Incidence rate = No of high risk behaviors / Follow-up person years
To avoid the values being too small, all incidence rates in Tables 1, 2, 3 and 4 were multiply by 100%
