Data were collected by physical examination and pretested semi-structured questionnaire from March 1 to 31, 2018. Collected data were entered in EpiData 3.1 and analyzed by using SPSS version 20. Bivariable and multivariable logistic regressions were done via the forward stepwise method. Variables were declared statistically significant when p-value < 0.05.Results: Of the total study participants, 75 (55%) of cases and 62 (46.6%) of controls were males. The mean age (± SD) of cases was 36.2 (± 14.2) years and that of controls was 31.4 (± 10.3) years. The classification table revealed that the sensitivity of cases was 70.7%, and the specificity of controls was 74.8%. This study showed that 28 (20.89%) of cases and 6 (4.5%) of controls had confirmed gastritis (P < 0.05). Regarding dental health information, 78 (58.2%) of cases and 123 (92.5%) of controls perceived that they had received dental health information from different sources. Access to dental health information and tooth brushing practice reduced dental health problems (adjusted odds ratio (AOR) = 0.28; 95% CI: 0.12, 0.64; and AOR = 0.24; 95% CI: 0.13, 0.45), respectively, whereas study participants who had gastritis were at increased risk of developing dental health problems (AOR = 3.12; 95% CI: 1.14, 8.57).Interpretation: Study participants who had adequate information on dental health had a reduced risk of developing dental health problems by 72% and participants who practiced tooth brushing were at reduced risk of developing dental health problems by 76%. However, individuals who had gastritis were 3 times more likely to develop dental health problems compared with their counterparts.Conclusion: In summary, health information, tooth brushing practice, and gastritis infection were the determinants of dental health problems. Thus, health information dissemination on dental health particularly on how to prevent and control dental health problems is very critical. Moreover, strategies to combat gastritis integrated with life course principles should be strengthened to improve dental health.Keywords: dental health, Ethiopia, gastritis, health information, tooth brushing

ABSTRACT The effects of soil bunds on runoff, losses of soil and nutrients, and crop yield are rarely documented in the Central Highlands of Ethiopia. A field experiment was set up consisting of three treatments: (i) barley-cultivated land protected with graded soil bunds (Sb); (ii) fallow land (F); and (iii) barley-cultivated land without soil bund (Bc). For 3 years (2007-2009), the effect of soil bunds on runoff, losses of soil and nutrients, and crop productivity was studied. Daily runoff and soil and nutrient losses were measured for each treatment using standard procedures while barley yield was recorded from the cultivated plots. The results showed that Sb brought about significant reduction in runoff and soil losses. Plots with Sb reduced the average annual runoff by 28 per cent and the average annual soil loss by 47 per cent. Consequently, Sb reduced losses of soil nutrients and organic carbon. However, the absolute losses were still high. This implies the need for supplementing Sb with biological and agronomic land management measures to further control soil erosion. Despite these positive impacts on soil quality, Sb do not increase crop yield. Calculated on a per-hectare basis, Sb even reduce crop yield by about 7 per cent as compared with control plots, which is entirely explained by the reduction of the cultivable area by 8·6 per cent due to the soil bunds. Suitable measures are needed to compensate the yield losses caused by the construction of soil bunds, which would convince farmers to construct these land management measures that have long-term beneficial effects on erosion control.

Smallholder dairy production represents a promising income generating activity for poor farmers in the developing world. Because of the perishable nature of milk, marketing arrangements for collection, distribution and sale are important for enhanced livelihoods in the smallholder dairy sector. In this study we examined the relationship between market quality and basic feeding and breeding practices at farm level. We define market quality as the attractiveness and reliability of procurement channels and associated input supply arrangements. We took as our study countries, India with its well-developed smallholder dairy sector, and Ethiopia where the smallholder dairy industry has remained relatively undeveloped despite decades of development effort. We conducted village surveys among producer groups in 90 villages across three States in India and two Regions in Ethiopia. Producer groups were stratified according to three levels of market quality – high, medium and low. Data showed that diet composition was relatively similar in India and Ethiopia with crop residues forming the major share of the diet. Concentrate feeding tended to be more prominent in high market quality sites. Herd composition changed with market quality with more dairy (exotic) cross-bred animals in high market quality sites in both India and Ethiopia. Cross-bred animals were generally more prominent in India than Ethiopia. Herd performance within breed did not change a great deal along the market quality gradient. Parameters such as calving interval and milk yield were relatively insensitive to market quality. Insemination of cross-bred cows was predominantly by artificial insemination (AI) in India and accounted for around half of cross-bred cow inseminations in Ethiopia. Data on perceptions of change over the last decade indicated that per herd and per cow productivity are both increasing in high market quality sites with a more mixed picture in medium and low-quality sites. Similarly dairy-derived income is on the increase in high market quality sites. This is accompanied by a strong increase in stall feeding at the expense of grazing. The study indicates that the first constraint to intensification of dairy production in Ethiopia is the genetic quality of the herd. There is less scope for improved AI provision in India since the cross-bred herd is mainly serviced by AI already. However, as for Ethiopia, there is considerable scope for closing yield gaps in India through improved feed use and supply. Results strongly show that well-developed markets with good procurement arrangements are key for sustainable dairy intensification. [ABSTRACT FROM PUBLISHER]
