Natural gas has become more and more important in the world energy market with the change of energy consumption structure and consumption subjects. This paper applies the panel smooth transition regression (PSTR) model to study the nonlinear relationship between natural gas consumption and economic variables of emerging economies, and the empirical results show that: (1) There is a non-linear r...

The association between meat consumption and chronic disease incidence and mortality has been evaluated in hundreds of observational epidemiologic studies over the past 3 decades. However, there remains considerable scientific debate as to whether higher intakes of specific meat groups (eg, red meat, poultry, and fish) or individual meats (eg, beef, pork, and chicken) contribute independently t...

BACKGROUND Alcohol consumption is a major risk factor in the global burden of disease, with overall volume of exposure as the principal underlying dimension. Two main sources of data on volume of alcohol exposure are available: surveys and per capita consumption derived from routine statistics such as taxation. As both sources have significant problems, this paper presents an approach that tria...

An ecological correlation study was conducted to determine the association between consumption of coconut products and cardiovascular disease (CVD) deaths in Sri Lanka. Data on coconut consumption patterns from 1961 to 2006 were abstracted from the FAO database, and mortality data from reports of the Department of Census and Statistics, and UN databases. Correlational and regression analyses we...

Human longevity is influenced by environment and nutrition. We considered environmental and nutritional factors relating to longevity in Chinese cities. We found higher 85+/65+ distribution ratios, indicating enhanced longevity, in the coastal and southern regions of China. These areas also featured higher humidity, low standard deviation of monthly temperature, higher levels of selenium (Se) d...

Household scale economies are plausibly attributed to shared household public goods that make larger households better off at the same level of per capita resources. Larger households should therefore have higher per capita consumption of private goods, such as food, provided that they do not substitute too much toward the effectively cheaper public goods. The evidence shows exactly the opposit...

This paper investigates the relationship between cigarette consumption per capita net disposable income, cigarette price index, and per capita expenditure for education. In this empirical analysis the Johansen cointegration test is applied in conjunction with the vector error correction model. Finally, the forecasting technique of cigarettes consumption in Greece using cointegration models is p...

BACKGROUND Methylmercury exposure causes a variety of adverse effects on human health. Per capita estimates of mercury exposure are critical for risk assessments and for developing effective risk management strategies. OBJECTIVE This study investigated the impact of natural stochasticity in mercury concentrations among fish and shellfish harvested from the Atlantic Ocean, Pacific Ocean, and f...

In the U.S., tomatoes are only exceeded by potatoes in economic importance. Among fresh vegetable products, annual per capita consumption of fresh tomatoes is only exceeded by lettuce and potatoes. Consumption of fresh tomatoes has remained fairly constant at around 12.8 pounds for the past 10 years as compared to the consumption of processed tomatoes in the form of ketchup and sauces which has...
