[Epidemiological study on the trend of accidental deaths among children under five in Beijing, during 2003-2012]

To study the trend of accidental death among children under 5 years of age in Beijing.

Cases of death in children under 5 years old in Beijing, during 2003-2012 were collected, to analyze the strength and trends of accidental death, main causes of accident and its epidemiological features.

The overall accidental death was 8.47% of all death among children under 5 years old in Beijing during 2003-2012. During these 10 years, data showed a downward trend on the mortality rates on injuries (P < 0.05), especially on drowning, in 1-4 year old and rural children under five years of age. In 2012, the accidental death rate of children under five was 6.37/105. The 5 main causes of accidental deaths were suffocation, traffic accident, falling, poisoning and drowning, in order of size. The main causes of death were suffocation in the 0-1 year group, suffocation and traffic accident in the 1-2 year group and traffic accident in the 3-4 year group. The proportion of deaths due to traffic accident increased gradually with age. Area distribution showed that accidental deaths mainly happened in rural area (52.19%), with two main types as traffic accident and suffocation.

The reduction of accidental death rate among children under 5 years old in Beijing mainly was caused by the decline of accident mortality in 1-4 year old and children in the rural areas. Our data suggested that the focus in reducing the accidental death rate among children under 5 years old in Beijing should target on the prevention of infant suffocation and traffic accidents among the 1-4 year old, with rural areas in particular.
