Objective:
Recent studies have suggested a weakening of the relationship between population drinking and harm in Sweden. The aim of the present article was to estimate this association on the basis of more recent Swedish time-series data.
Method:
The Swedish state monopoly's (Systembolaget) alcohol sales were used as a proxy for population drinking, expressed in liters 100% alcohol per capita ages 15 and older. As indicators of harm we used mortality (cirrhosis mortality, accidents, and suicide), police-reported assaults, and drink driving. Quarterly data on mortality and alcohol consumption spanned the period 1987Q1-2015Q1, and the data on police-reported offenses covered the period 1995Q1-2015Q1. Data were analyzed by applying the technique of seasonal autoregressive integrated moving average (SARIMA) modeling.
Results:
We found a positive and statistically significant association between population drinking and all harm indicators. A 1 L increase in per capita consumption was associated with a 19% increase in cirrhosis mortality and a 17% increase in drink driving. The effects on the other harm rates were estimated to be between 11% and 13%. These estimates are in line with earlier findings except the estimate for cirrhosis, which was weaker and now similar to findings for other countries.
Conclusions:
The results provide continuing support for a strong relationship between population drinking and alcohol-related harm in Sweden. Policy measures aimed at lowering the level of drinking gained support from these results.

02:37Oxidation of Alcohols
The process of oxidation in a chemical reaction is observed in any of the three forms:
02:29Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.
02:31Protection of Alcohols
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
01:38Preparation of Alcohols via Substitution Reactions
Alcohols can be synthesized from alkyl halides via nucleophilic substitution reactions. The highly polar carbon-halogen bond in the substrate makes halide a good leaving group. The hydroxide ion or water can act as a nucleophile to take the place of halide and form an alcohol. The substitution reactions occur via two different reaction pathways, SN1 or SN2, depending on the nature of carbon attached to the halide.
Primary alcohols are synthesized from primary alkyl halides, and the...
01:17Esters to Alcohols: Hydride Reductions
Lithium aluminum hydride is a source of hydride ions and functions as a nucleophile. The mechanism proceeds in three steps. Firstly, the nucleophilic hydride ion attacks the carbonyl carbon of the ester to form a tetrahedral intermediate. Subsequently, the carbonyl group re-forms,...
01:08Esters to Alcohols: Grignard Reaction
The reaction requires two equivalents of the Grignard reagent and introduces two identical alkyl groups, derived from the Grignard reagent, bonded to the hydroxyl-bearing carbon of the alcohol.
The reaction follows the typical nucleophilic acyl substitution mechanism. The Grignard...
