Where do the children play? An objective analysis of children's use of green space.

Green space is important for health, yet, objective research on children's use of green space is sparse. This study aimed to objectively assess children's use of green space in both public and private settings during their summer leisure time, using wearable cameras. Images from cameras worn by 74 children were analysed for green space use over 4 days. Children spent an average of ∼1/10 h of leisure time in green space in the summer months, were physically active 68%, and with others 85%, of the time. Green spaces are important places for children's health because they are places they frequent and places where they are physically active and socialize. Wearable cameras provide an effective method for objective assessment of green space use.

Care versus convenience: Examining paracetamol overdose in New Zealand and harm reduction strategies through sale and supply.

AIM: To examine statistics on paracetamol overdose in New Zealand and investigate options to reduce paracetamol overdose rates, through supply reduction strategies. METHOD: Data was gathered from the Ministry of Health's National Minimum Dataset and Wellington Hospital Emergency Department attendances. Twenty articles on supply reduction strategies were sourced through article database searches. A survey on paracetamol availability from online pharmacies within New Zealand was conducted by searching for New Zealand online pharmacies through Google. RESULTS: A five-year audit of data (2007-2012) from the Wellington Hospital Emergency Department revealed that paracetamol was the most common medication used for overdose (23%). National data on aminophenol derivatives accounted for 22.4% of poisonings in New Zealand's public hospitals. An online search found that 25 out of 27 online pharmacies sold packets containing 50 grams of paracetamol. However, the literature supported restricting packets to the minimum threshold for an acute exposure (10 g). CONCLUSION: Paracetamol poisoning is the most common form of drug overdose in many developed countries. Tightening restrictions on the quantity of paracetamol sold per packet, in all outlets in New Zealand, may be an effective strategy to reduce overdose rates. This includes online pharmacies where large quantities of paracetamol per packet are available for sale.
