Vitamin D plays an important role in skeletal health throughout life. Some studies have hypothesised that vitamin D may reduce the risk of other diseases. Our study aimed to estimate age-specific and sex-specific serum 25-hydroxyvitamin D (25(OH)D) status and to identify the determinants of serum 25(OH)D status in Hong Kong, a subtropical city in southern China. In 2009–2010, households in Hong Kong were followed up to identify acute respiratory illnesses, and sera from 2694 subjects were collected in three to four different study phases to permit measurement of 25(OH)D levels at different times of the year. A questionnaire survey on diet and lifestyle was conducted among children, with simultaneous serum collection in April and May 2010. The mean of serum 25(OH)D levels in age groups ranged from 39 to 63 nmol/l throughout the year with the mean values in all age groups in spring below 50 nmol/l. Children aged 6–17 years, and girls and women had significantly lower serum 25(OH)D levels than adults, and boys and men, respectively (allP< 0·001). We estimated that serum 25(OH)D levels in Hong Kong followed a lagged pattern relative to climatic season by 5 weeks with lowest observed levels in early spring (March). For children aged 6–17 years, reporting a suntan, having at least 1 servings of fish/week and having at least 1 serving of eggs/week were independently associated with higher serum 25(OH)D levels. Adequate sunlight exposure and increased intake of dietary vitamin D could improve vitamin D status, especially for children and females in the winter and spring.

Prologue: Business Environment and Economic BehaviorFor more than two decades, sociologists, historians and economic geographers have produced many case studies on Chinese family businesses. A major consensus of these works suggests that ‘networking’, especially ethnic and familial, is extremely important to Chinese businesses. Various models and theories have been employed to explain this phenomenon. Notable among these explanations is the idea of Chinese entrepreneurship. According to this idea, such ethnicity-based groups as the Cantonese and the Fujianese (of the provinces of Guangdong and Fujian), are regarded to be culturally oriented towards business entrepreneurship and the cultivation of business networks. Before the outbreak of the Asian economic crisis in October 1997, many researchers believed that ‘Chinese entrepreneurship’ and the ‘business culture of networking’ contributed to the success of Chinese businesses in Asia (especially in the ‘Four Little Dragons’ of coastal Asia). For example, Confucian ethics and its emphasis on familial and ethnic networks is regarded as an asset for business expansion by Chinese international enterprises based in Hong Kong, Taiwan and Singapore. After the outbreak of the crisis, more research on the nature of Chinese entrepreneurship and the culture of networking was carried out. This research started from a different angle. The reliance on politically secured economic privileges (i.e.; nepotism), was identified as a defect of networking and thus, one of the major underlying causes of the crisis. The claim that the culture of networking contributes to business success actually offers a readily available explanation for its failure as well (see for examples Redding, 1990; Yeung, 1997; Yeung, 1998).

Hong Kong was a UK colony before 1997 but has since been a Special Administrative Region of the People's Republic of China. It is located in southern China and has an area of 1104 km2. Approximately 95% of Hong Kong's population is ethnic Chinese. Hong Kong is a developed capitalist economy, with a gross domestic product of US$301.6 billion (2009 estimate), of which about 5.5% is spent on healthcare and about 0.24% on mental health (World Health Organization, 2005). Despite the relatively low level of spending on healthcare, Hong Kong nevertheless has one of the longest life expectancies in the world (79.2 years for men; 84.8 years for women) and a very low infant mortality rate (2.93 per 1000 live births) (Central Intelligence Agency, 2010).

ABSTRACTObjective: We investigated local media reporting during the emergence of influenza A/Hong Kong/68 in Hong Kong to understand how indolent social awareness contributed to delays in warning of the pandemic.Methods: Daily output from 1 English-language and 4 local Chinese-language newspapers published in Hong Kong between July 1 and August 31, 1968 were manually reviewed for all references to the presence of respiratory disease or influenza in southern China and Hong Kong. Public announcements from the World Health Organization Weekly Epidemiological Record were used to approximate international awareness.Results: Influenza A/Hong Kong/68 appeared abruptly in Hong Kong and within 1 week began to affect the functioning of the health care sector as well as civil infrastructure due to worker infection and absenteeism. Substantial delays in communication between Guangzhou, China, and Hong Kong officials contributed to delays in warning globally.Conclusions: The 1968 experience emphasizes the need to use the news media in the operational setting as a critical component in warning of a pandemic.
