Comparisons of complementary feeding indicators among children aged 6-23 months in Anglophone and Francophone West African countries.

Stunting, a consequence of suboptimal complementary feeding practices, continues to be a significant public health problem in West Africa. This paper aimed to compare rates of complementary feeding indicators among children aged 6-23 months between four Anglophone and seven Francophone West African countries. The data used for this study were the most recent Demographic and Health Surveys of the various countries, namely Ghana, Liberia, Nigeria, Sierra Leone (Anglophone countries), Benin, Burkina Faso, Cote d'Ivoire, Guinea, Mali, Niger and Senegal (Francophone countries) conducted between 2006 and 2013. The analyses were limited to last-born children aged 6-23 months and covered 34 999 children: 12 623 in the Anglophone countries and 22 376 children in the Francophone countries. Complementary feeding indicators were examined using the method proposed by the World Health Organization (WHO) in 2008. Introduction of solid, semi-solid or soft foods among children aged 6-23 months in the Anglophone countries ranged from 55.3% (Liberia) to 72.6% (Ghana). The corresponding rates for the Francophone countries ranged from 29.7% (Mali) to 65.9% (Senegal). The average rate of minimum dietary diversity for the Anglophone countries was 32.0% while that of the Francophone countries was only 10.6%. While the minimum meal frequency rates ranged between 42.0% (Sierra Leone) and 55.3% (Nigeria) for the Anglophone countries, the corresponding rates for the Francophone countries ranged between 25.1% (Mali) and 52.4% (Niger). Both the Anglophone and the Francophone countries reported alarmingly low rates of minimum acceptable diet, with the two groups of countries averaging rates of 19.9% (Anglophone) and 5.5% (Francophone). The rates of all four complementary feeding indicators across all the 11 countries fell short of the WHO's requirement for optimal complementary feeding practices. Intervention studies using cluster-randomised controlled trials are needed in order to improve the nutritional status of young children in West Africa.

Determinants of suboptimal complementary feeding practices among children aged 6-23 months in seven francophone West African countries.

Suboptimal complementary feeding practices play a crucial role in the health and development of children. The objective of this research paper was to identify factors associated with suboptimal complementary feeding practices among children aged 6-23 months in seven francophone West African countries, namely, Benin, Burkina Faso, Cote d'Ivoire, Guinea, Mali, Niger and Senegal. This study covered 22 376 children aged 6-23 months from the seven countries surveyed (Benin: 3732 children; Burkina Faso: 4205 children; Cote d'Ivoire: 2109 children, Guinea: 1944 children, Mali: 3798 children, Niger: 3451 children and Senegal: 3137 children). The most recent Demographic and Health Survey datasets of the various countries were used as data sources. A set of individual-, household- and community-level factors were used to examine the four complementary feeding indicators. Multivariate analysis revealed that the youngest age bracket (6-11 months) of children, administrative/geographical region, mother's limited or non-access to the mass media, mothers' lack of contact with a health facility, rural residence, poor households and non-working mothers were the main factors associated with suboptimal complementary feeding in the countries surveyed. Our findings highlight the need to consider broader social, cultural and economic factors when designing child nutritional interventions.

Determinants of suboptimal complementary feeding practices among children aged 6-23 months in four anglophone West African countries.

Suboptimal complementary feeding practices have a detrimental impact on a child's growth, health and development in the first two years of life. They lead to child malnutrition, which contributes to the high prevalence of stunting (38%) and underweight (28%) reported for children <5 years of age in Sub-Saharan Africa. This study analysed complementary feeding practices in four anglophone West African countries (Ghana, Liberia, Nigeria and Sierra Leone) using the most recent Demographic and Health Surveys. The study covered 12 623 children aged 6-23 months from four anglophone West African countries (Ghana: 822 children: Liberia: 1458 children, Nigeria: 8786 children and Sierra Leone: 1557 children). Four complementary feeding indicators were examined against a set of individual-, household- and community-level factors, using multiple regression analysis. Multivariate analyses found that lack of post-natal contacts with health workers, maternal illiteracy and geographical region were common determinants of delayed introduction of solid, semi-solid or soft foods across all four countries. Predictors for minimum dietary diversity, minimum meal frequency and minimum acceptable diet included children aged 6-11 months, administrative/geographical region, poorer household income and limited access to media. The authors recommend that the four anglophone West African countries studied should prioritise efforts to improve complementary feeding practices in order to reduce child morbidity and mortality. Interventional studies on complementary feeding should target those from poor and illiterate households.

The problem of suboptimal complementary feeding practices in West Africa: what is the way forward?

The objective of this paper was to review the policy implications of inadequate complementary feeding among children aged 6-23 months in West Africa. The review was undertaken from the initial results and findings from a series of studies on the comparison of complementary feeding indicators among children aged 6-23 months in four anglophone and seven francophone West African countries. It also examined a study of the determinants of suboptimal complementary feeding practices among children aged 6-23 months in those countries. Among the four complementary feeding indicators, it was only the introduction of solid, semi-solid or soft foods that was adequate among children in all the West African countries surveyed. The rates of the other complementary feeding indicators were found to be inadequate in all countries surveyed, although relatively better among children in the anglophone countries. Alarmingly, low rates of minimum acceptable diet were reported among children from both the anglophone and the francophone countries. Infants 6-11 months of age, children living in poor households, administrative/geographical regional differences and mothers' access to the media were some of the common risk factors for optimal complementary feeding practices in these countries. Assessing complementary feeding indicators and determinants of suboptimal complementary feeding practices in these West African countries is crucial to improving infant and young child feeding practices. It is recommended that governments and stakeholders of the West African countries studied make greater efforts to improve these critical practices in order to reduce child morbidity and mortality in the West Africa sub-region. Intervention studies on complementary feeding should target those socio-demographic factors that pose risks to optimal complementary feeding.

General practitioner attitudes to prescribing hepatitis C antiviral therapy in a community setting.

There is a growing debate about the prescription of hepatitis C virus (HCV) antiviral therapies within a community setting in Australia. This study aimed to identify interest and confidence among general practitioners (GPs) in prescribing HCV antiviral therapy in a community setting. Data from 580 GPs who responded to a cross-sectional population-based survey were analysed to measure: self-reported interest and confidence in initiating HCV antiviral therapy; and/or prescribing maintenance antiviral therapy; and self-perceived education needs about HCV antiviral therapy. Forty-two percent of respondents indicated they would be interested in prescribing HCV antiviral therapy. Most were not confident to initiate therapy (80%). Higher proportions indicated that they would be more confident in prescribing maintenance therapy (35%) rather than initiating (7%) therapy (z=10.5, P<0.001). Confidence in prescribing was related to a higher caseload of patients with HCV (P=0.001) and being a HIV community-based prescriber (P=0.002). Fifty-three percent of respondents expressed an interest in education about HCV antiviral therapy. The initial step to recruit potential primary care prescribers of HCV antiviral therapies should be to develop an integrated education program. Recruitment to this program might be most efficient from GPs with a high caseload of patients with HCV.

The decline in Australian young male suicide.

Since the late 1990s there has been a sharp downward trend in Australian young male suicide. It is possible that a major government youth suicide prevention initiative, the National Youth Suicide Prevention Strategy (NYSPS), implemented during 1995-1999 may have influenced the decline. In this article, we examine time trends in age- and means-specific male and female Australian suicide rates in relation to unemployment rates and the NYSPS. Based on Australian suicide data over the period 1966-2003, we assess secular changes in the 20-24 year male suicide to total (crude) male suicide rate ratio in relation to the NYSPS, using interrupted time series analysis (ARIMA), since this was previously found to be significantly associated with the 20-24 year male unemployment to total employment ratio. Results show that a dramatic reduction in Australian young male (aged 20-34 years) suicide has occurred since 1997-1998, declining from approximately 40 per 100,000 in 1997-1998 to approximately 20 per 100,000 in 2003. Most of the decline is due to a decrease in suicide by hanging and to a lesser extent from motor vehicle carbon monoxide and other gases. Further, the previously established strong secular association (lasting over 3 decades from 1966) between the rate ratio of 20-24 year male suicide to total (crude) male suicide, and the rate ratio of 20-24 year male unemployment to total unemployment, appears to have been disrupted. ARIMA modelling of the suicide ratio against the initiative indicates a highly significant statistical association between the NYSPS and the suicide ratio reduction but not between the NYSPS and the unemployment indicator trend, suggesting a break in the link between young male suicide and unemployment. The recent sudden turnaround in Australian young male suicide trends and its extent appears to preclude explanations centring on slow-moving social indices traditionally associated with suicide, or on possible cohort effects. This sudden decrease has occurred mainly in non-impulsive means, and at the same time has broken a long-standing secular link between 20 and 24-year-male suicide and unemployment, lending plausibility to the case for the NYSPS having had an impact on young male suicide in Australia.

Factors associated with early introduction of formula and/or solid, semi-solid or soft foods in seven Francophone West African countries.

The aim of this study was to identify factors associated with early introduction of formula and/or solid, semi-solid or soft foods to infants aged three to five months in seven Francophone West African countries. The sources of data for the analyses were the most recent Demographic and Health Survey datasets of the seven countries, namely Benin (BDHS, 2012), Burkina Faso (BFDHS, 2010), Cote d'Ivoire (CIDHS, 2011-2012), Guinea (GDHS, 2012), Mali (MDHS, 2012-2013), Niger (NDHS, 2012) and Senegal (SDHS, 2010). The study used multiple logistic regression methods to analyse the factors associated with early introduction of complementary feeding using individual-, household- and community-level determinants. The sample was composed of 4158 infants aged between three and five months with: 671 from Benin, 811 from Burkina Faso, 362 from Cote d'Ivoire, 398 from Guinea, 519 from Mali, 767 from Niger and 630 from Senegal. Multiple analyses indicated that in three of the seven countries (Benin, Guinea and Senegal), infants who suffered illnesses, such as diarrhoea and acute respiratory infection, were significantly more likely to be introduced to formula and/or solid, semi-solid or soft foods between the age of three and five months. Other significant factors included infants who: were born in second to fourth position (Benin), whose mothers did not attend any antenatal clinics (Burkina Faso and Niger), were male (Cote d'Ivoire and Senegal), lived in an urban areas (Senegal), or were delivered by traditional birth attendants (Guinea, Niger and Senegal). Programmes to discourage early introduction of formula and/or solid, semi-solid or soft foods in these countries should target the most vulnerable segments of the population in order to improve exclusive breastfeeding practices and reduce infant mortality.

The impact of water and sanitation on childhood mortality in Nigeria: evidence from demographic and health surveys, 2003-2013.

In Nigeria, approximately 109 million and 66 million people lack access to sanitation facilities and water, respectively. This study aimed to determine whether children under 5 years old without access to improved water and sanitation facilities are at higher risk of death in Nigeria. Pooled 2003, 2008 and 2013 Nigeria Demographic and Health Survey data were used to examine the impact of water and sanitation on deaths of children aged 0-28 days, 1-11 months, and 12-59 months using Cox regression analysis. Survival information of 63,844 children was obtained, which included 6285 deaths of children under 5 years old; there were 2254 cases of neonatal mortality (0-28 days), 1859 cases of post-neonatal mortality (1-11 months) and 2,172 cases of child mortality (1-4 years old). Over a 10-year period, the odds of neonatal, post-neonatal and child deaths significantly reduced by 31%, 41% and 47% respectively. The risk of mortality from both unimproved water and sanitation was significantly higher by 38% (Adjusted hazard ratios (HR) = 1.38, 95% confidence interval (CI): 1.14-1.66) for post-neonatal mortality and 24% (HR = 1.24, 95% CI: 1.04-1.48) for child mortality. The risk of neonatal mortality increased by 6% (HR = 1.06, 95% CI: 0.85-1.23) but showed no significant effect. The Nigerian government needs to invest more in water and sanitation to reduce preventable child deaths.

Determinants of early introduction of solid, semi-solid or soft foods among infants aged 3-5 months in four Anglophone West African countries.

This study was conducted to explore and identify factors associated with the practice of early introduction of solid, semi-solid or soft foods among infants aged 3-5 months in four Anglophone West African countries. Data sources for the analyses were the latest Demographic and Health Survey datasets of the 4 countries, namely Ghana (GDHS, 2008), Liberia (LDHS, 2007), Nigeria (NDHS, 2013) and Sierra Leone (SLDHS, 2008). Multiple logistic regression methods were used to analyze the factors associated with early introduction of solid, semi-solid or soft foods among infants aged 3-5 months, using individual-, household- and community-level determinants. The sample consisted of 2447 infants aged 3-5 months from four Anglophone West African countries: 166 in Ghana, 263 in Liberia, 1658 in Nigeria and 360 in Sierra Leone. Multivariable analyses revealed the individual factors associated with early introduction of solid, semi-solid or soft foods in these countries. These included increased infant's age, diarrhea, acute respiratory infection and newborns perceived to be small by their mothers. Other predictors of early introduction of solid, semi-solid or soft foods were: mothers with no schooling, young mothers and fathers who worked in an agricultural industry. Public health interventions to improve exclusive breastfeeding practices by discouraging early introduction of solid, semi-solid or soft foods are needed in all 4 countries, targeting especially mothers at risk of introducing solid foods to their infants early.

Population attributable risk of modifiable risk factors associated with invasive breast cancer in women aged 45-69 years in Queensland, Australia.

OBJECTIVES: To quantify the population attributable risk of key modifiable risk factors associated with breast cancer incidence in Queensland, Australia. STUDY DESIGN: Population attributable fractions (PAFs) for high body mass index (BMI), use of hormone replacement therapy (HRT), alcohol consumption and inadequate physical activity were calculated, using prevalence data from a representative survey of women attending mammographic screening at BreastScreen Queensland in 2008 and relative risk estimates sourced from published literature. Attributable cancers were calculated using 'underlying' breast cancer incidence data for 2008 based on Poisson regression models, adjusting for the inflation of incidence due to the effects of mammographic screening. MAIN OUTCOME MEASURES: Attributable burden of breast cancer due to high body mass index (BMI), use of hormone replacement therapy (HRT), alcohol consumption and inadequate physical activity. RESULTS: In Queensland women aged 45-69 years, an estimated 12.1% (95% CI: 11.6-12.5%) of invasive breast cancers were attributable to high BMI in post-menopausal women who have never used HRT; 2.8% (95% CI: 2.7-2.9%) to alcohol consumption; 7.6% (95% CI: 7.4-7.9%) to inadequate physical activity in post-menopausal women and 6.2% (95% CI: 5.5-7.0%) to current use of HRT after stratification by BMI and type of HRT used. Combined, just over one quarter (26.0%; 95% CI: 25.4-26.6%) of all invasive breast cancers in Queensland women aged 45-69 years in 2008 were attributable to these modifiable risk factors. CONCLUSIONS: There is benefit in targeting prevention strategies to modify lifestyle behaviours around BMI, physical activity, HRT use and alcohol consumption, as a reduction in these risk factors could decrease invasive breast cancer incidence in the Queensland population.

Sociodemographic correlates of antidepressant utilisation in Australia.

OBJECTIVE: To investigate sociodemographic variation in antidepressant utilisation. DESIGN AND SETTING: Cross-sectional analysis of antidepressant prescription under the Pharmaceutical Benefits Scheme in Australia, 2003-2005. MAIN OUTCOME MEASURES: Antidepressant utilisation (defined daily dose/1000/day) by sex, age, socioeconomic status (SES) and geographical area. RESULTS: Total antidepressant utilisation increased with age. Among those aged > or = 15 years, female utilisation was about double that of males. About half of antidepressant utilisation was accounted for by sertraline, venlafaxine, citalopram, and paroxetine. SES differentials in antidepressant utilisation changed across age groups for males and females: among those aged < or = 19 years, total antidepressant utilisation was significantly less in lower SES groups (P < 0.001); there was no relationship to SES among 20-29-year-olds; and among those aged > or = 30 years, antidepressant utilisation was significantly higher in lower SES groups (P < 0.001). SES differences were attenuated after adjusting for urban or rural residence, but remained statistically significant. Antidepressant utilisation rates were highest in regional centres. CONCLUSION: Antidepressant utilisation in Australia partially reflects sociodemographic differences in the prevalence of affective disorder. Discrepancies between treatment provision and treatment need suggest that not all social strata in Australia have equal access to these treatments.

Suicide in Australian farming, 1988-1997.

OBJECTIVES: To identify and describe suicide data for occupational classifications relating to farm managers and agricultural labourers for Australia for the period 1988 to 1997, and to relate resultant suicide rates to farmers' terms of trade. METHOD: Descriptive and linear regression analysis of aggregated mortality data. RESULTS: In the period 1988 to 1997, 921 suicides were identified. The majority of these suicides were farm managers (67.4%). Farm manager suicides occurred predominantly in older age groups (55 + years). In comparison agricultural labourer suicides were younger, with the majority of suicides occurring in the 15-39 years age group. The most common methods for both groups were firearms (particularly hunting rifles and shot guns), hanging and motor vehicle exhaust gas. These methods accounted for approximately 81% of all male farm suicides. Firearms accounted for 51% of male farm suicide, in comparison to 23% for the wider Australian male population for the same period. Estimated age standardized rates per 100 000 for male farm managers for the 10-year period ranged from 24.8 to 51.4. For male agricultural labourers these rates ranged from 23.5 to 41.9. Analyses also revealed a negative correlation (r = -0.75, p < 0.01) between farm manager suicide rates and farmers' terms of trade. CONCLUSION: Male farm manager and agricultural labourer suicide rates are higher than male national rates and rates in the wider rural population, particularly in the later years of the period investigated. Firearms prefigure as the most common method of suicide, despite decreases in this method in the wider rural population. Establishing more accurate denominator data for the farming community is a priority, as is preventative action that accounts for unique aspects of farm life.
