Data from a longitudinal study carried out in Dunedin, New Zealand, were used to investigate associations between alcohol consumption at age 18 years and alcohol-related mass media communications recalled at ages 13 and 15 years. The respondents' recall of alcohol-related mass media material were categorized as: commercial alcohol advertising, alcohol moderation messages or the portrayal of alcohol in entertainment. An additional media variable was the number of hours spent watching television. Non-media variables, such as peer approval of drinking, living situation and occupation (all at age 18 years) were also included in the analyses. The period between the interviews at ages 13 and 15 years saw an increase in the broadcast of commercial alcohol advertisements on television in New Zealand and this was reflected in an increase in the proportion of the mass media material recalled which was categorized as commercial advertising. At age 15 years television advertising, mostly for beer companies, was the predominant material recalled. No relationships were found between the commercial advertising and wine and spirits consumption, among either men or women, but young women who had watched more hours of television drank more wine/spirits. Among women there were two unexpected negative relationships between recall of alcohol in the media at age 13 years and beer consumption. However, among men there was a consistent positive relationship such that those who had recalled more alcohol advertisements at age 15 years drank larger quantities of beer at age 18 years.

This measurable impact of alcohol advertising occurred during a time of decline in aggregate alcohol in New Zealand. While this effect was not large enough to halt the decline in aggregate alcohol consumption it does indicate a measurable, specific impact of broadcast alcohol advertising on alcohol consumption and related behaviour which is of relevance for public health policy.

The local stability is rather difficult to be restored to the original levels regardless the length of iliac screws. Obviously, long iliac screws resisted significantly greater axial pullout force. However, under physiologic, torsional, and compressive loading conditions, the mechanical stability of lumbo-pelvic fixation construct with short iliac screws was comparable with that of the long ones. Therefore, the use of short iliac screws, which are only about half the length of the long iliac screws, could reduce the implantation risk without significantly compromising on the stability of the construct.

In the urban setting of Wuhan, over the time-period 2002-05, there was an increase in prevalence of drinkers, particularly among younger people and older women. The average frequency and quantities consumed by drinkers did not change over this period; among drinking men the volumes of alcohol consumed were comparable to those in much more saturated commercial alcohol markets. The results did, however, show an increase over time in the proportion of older men who were engaged in heavier drinking and, in 2005, the proportion exceeded that in more saturated markets. These data suggest that, given the relatively high levels of consumption among established drinking groups, increases in the prevalence of drinkers over time may result in increases in harm if effective policies are not implemented.
